Abstract:

Patients with heart failure may benefit from implantation of a biventricular pacemaker. This article discusses the indications for biventricular pacemaker implantation and the assessment of patients with biventricular pacemakers. Biventricular pacemakers require more assessments than do traditional single- or dual-chamber pacemakers.

Abstract:

Abstract Introduction: Pacemaker implantation is the only effective symptomatic treatment for life-threatening bradyarrhythmias. Major complications observed after implantation of cardiac pacemakers include lead dislocation, loss of pulse generator function, and inadequate stimulation. The aim of this retrospective single-centre study was to analyse the indications for pacemaker implantation and the incidence and types of complications associated with this procedure in dogs treated for symptomatic bradyarrhythmia. Material and Methods: The retrospective analysis included 31 dogs with symptomatic bradyarrhythmia, implanted with permanent cardiac pacemakers in 1992–2017. The list of analysed variables included patient age, breed, sex, indication for pacemaker implantation, comorbidities, and the incidence of procedure-related complications along with the type thereof. Results: The most common indication for pacemaker implantation was 3rd degree AVB, followed by SSS, advanced 2nd degree AVB, and PAS. Pacemaker implantation was associated with a 35% overall complication rate and 6.45% periprocedural mortality. There were no significant differences in terms of procedure-related complications with regard to age, sex, breed, indications for pacemaker implantation, or comorbidities. Conclusions: Cardiac pacing is the only effective treatment of symptomatic bradycardia, but as an invasive procedure, may pose a risk of various complications, including death.

Abstract:

Temporary pacemakers are classically indicated for severe bradydysrhythmia, especially when the clinical settings require prompt intervention. Implantation of a temporary pacemaker is not a benign procedure since it may be associated with serious adverse events such as infection, cardiac perforation, and lead dislodgment. Accordingly, we recommend, when the clinical condition allows, to proceed directly with permanent pacemaker implantation without prior use of a temporary pacemaker. However, if a temporary pacemaker is required, it should be maintained for the shortest time possible. This policy allows avoiding or decreasing the potential complications associated with temporary pacemaker implantation.

Abstract:

Background: To determine the demographic details, indications, type of pacemakers and complications in patients undergoing the permanent pacemaker implantation.Methods: This was a single-center, retrospective study conducted in at a tertiary-care center in India. The records of 200 patients who had undergone implantation of permanent pacemakers in the period of May 2016 to April 2018 were reviewed.Results: Total 200 patients with mean age of 67 years were paced. Of these 120 (60%) were males. The mean duration of hospital stay was 6.5 days. Sinus node disease (105 patients, 52.5%) was the most common indication for permanent pacemaker insertion. Single chamber (VVIR) pacing mode (125 patients, 62.5%) was found to be the most common pacing mode used for pacemaker insertion. Among the 200 patients complications were observed in 8 patients (4%). Of these 8 patients, pneumothorax (4 patients, 2%) was found to be the most common complication for permanent pacemaker implantation followed by local site infection (1 patient, 0.5%). Only 1 patient (0.5%) died during the observation period of the study.Conclusions: Geriatric population with male predominance have observed to commonly undergo permanent pacemaker implantation. Sinus node disease in the elderly patients is the most common indication for cardiac pacing followed by atrioventricular block. Single chamber (VVIR) pacing mode is commonly used followed by dual chamber (DDDR) due to economic reasons in India. Pacemaker implantation is a relatively safe procedure with a low complication rate.

Abstract:

✓ Deep brain stimulation (DBS) has become an important modality in the treatment of refractory Parkinson disease (PD). In patients with comorbid arrhythmias requiring cardiac pacemakers, DBS therapy is complicated by concerns over a possible electrical interaction between the devices (or with device programming) and the inability to use magnetic resonance imaging guidance for implantation. The authors report two cases of PD in which patients with preexisting cardiac pacemakers underwent successful implantation of bilateral DBS electrodes in the subthalamic nucleus (STN). Each patient underwent computerized tomography—guided stereotactic frame—based placement of DBS electrodes with microelectrode recording. Both extension wires were passed from the right side of the head and neck (contralateral to the pacemaker) to place the cranial pulse generators subcutaneously in the left and right abdomen. The cranial pulse generators were placed farther than 6 in from the cardiac pacemaker and from each other to decrease the chance of interference between the devices during telemetry reprogramming. Postoperative management involved brain stimulator programming sessions with simultaneous cardiological monitoring of pacemaker function and cardiac rhythm. No interference was noted at any time, and proper pacemaker function was maintained throughout the follow-up period. With bilateral STN stimulation, both patients experienced a dramatic improvement in their PD symptoms, including elimination of dyskinesias, reduction of “off” severity, and increase of “on” duration. With some modifications of implantation strategy, two patients with cardiac pacemakers were successfully treated with bilateral DBS STN therapy for refractory PD. To our knowledge, this is the first report on patients with cardiac pacemakers undergoing brain stimulator implantation.

Abstract:

Background and Aims: The number of pacemaker implantation is increasing at various centres of Nepal with increase in cardiac services. However, there are few data available regarding the pacemaker implantation in Nepal. This study intend to focus and study trends and profile of permanent pacemaker implantation (PPI) of 19 years experience at the referral tertiary cardiac center which will reflect intended objective of this study. Methods: This was a retrospective cross sectional study done at Shahid Gangalal National Heart Centre (SGNHC). The data of the patient who underwent PPI from 2001 November to 2020 August were reviewed. Patients data including age, sex, indication for pacing, mode of pacing, type of pacemaker implanted, implantation parameters such as lead impedence and threshold were recorded and analyzed. Results: A total of 3631 pacemaker implantation were performed at SGNHC from 2001 November to 2020 August. Among the total patients, 59.4% were male with mean age of 65.2±15.2 years. The most common indication was degenerative complete heart block (74.8%). Sick sinus syndrome (8.2%) was the second most common indication of pacing. The single chamber were implanted in 93.3% cases and dual chamber in 6.7% cases. VVIR was the most common mode of implantation in 93.1% cases, followed by DDDR (6.7%). AAIR (0.1%) and VDD in 0.1% cases. The total number of pacemaker implanted yearly in SGNHC has increased since the early year of implantation. During the early years most of the pacemakers were Single chamber (VVI) pacemaker and the implantation of dual chamber pacemaker increased gradually from year 2010 onwards. After the year 2010 the implantation of dual chamber pacemaker has increased significantly compared to prior to 2010 (p= 0.001). There were no gender differences in use of single chamber and dual chamber implantation during this period. (p value = 0.489). The dual chamber were implanted mostly in age group less than 65 year compared to more than 65 years (P value = 0.001). Conclusion: There is gradual increase in the number of pacemaker implantation yearly at SGNHC and since 2010 there is also increase in number of dual chamber pacemaker implantation though the single chamber pacemaker outnumbered the dual chamber implantation.

Abstract:

Background: Allergic reaction to pacemaker compounds is a rare complication of cardiac pacing. Initial management is difficult because accurate diagnosis is often delayed. The tendency is to initially suspect a bacterial infection, rather than to quickly rule out an allergy to the pacemaker components. Management of this condition is difficult and not well established. Case presentation: A 75-year-old man underwent a dual chamber pacemaker implantation. The patient needed two generator re-implantations because of sterile skin necrosis. Pace maker allergic reaction was suspected despite non-conclusive skin patch testing. The patient underwent pacemaker system removal and re-implantation of poly-tetra-fluoro-ethylene sheet coated generator in a retropectoral position. Subsequently, there has been no externalization or recurrence in nine years of follow-up. Take-away lesson: Contact allergy to pacemakers is often unrecognized. Once infection has been excluded, allergy testing must be performed. The only valuable treatment is the removal of all the system components, followed by a replacement with hypoallergenic material. Polytetrafluoroethylene coated materials can be effective to prevent recurrence.

Abstract:

Despite the increasing use of permanent cardiac pacemakers in a younger patient population, there are little data related to pregnancy. Normal physiologic alterations of pregnancy need to be taken into account in the management of the pregnant woman with a pacemaker in place. Similarly, gestational events including the potential for surgical intervention require a basic knowledge of pacemaker technology and monitoring. We present a case of a patient with junctional escape rhythm and was implanted pacemaker during pregnancy. A 24 years old women referred from obstetric outpatient clinic with asymptomatic bradycardia and cryptogenic stroke 2 years earlier. ECG shows sinus arrest with junctional escape rhythm. After multi-disciplinary discussion, team decided to implant double chamber pacemaker implantation. The pacemaker setting is adjusted to prepare caesarean section at 39 weeks gestation with delivery of an aterm infant. The postoperative course was uneventful. Pre-pregnancy pacemaker settings were re-established after the postpartum period. The current literature on managing pregnant patients with pacemakers is quite limited. Such patients require a multidisciplinary approach to care. Electromagnetic Interference (EMI) should be noticed.

Abstract:

Permanent pacemaker implantation was carried out in 12 children with a mean age of 1.4 years (range, 2 days to 4 years) and a mean weight of 8.6 kg (range, 2.4–13.6 kg), using a single midline approach for placement of both the epicardial lead and the pacemaker generator (intermuscular abdominal implantation). Platinized porous-tipped steroid-eluting epicardial leads were used in all patients. The pacemakers worked well, and there was no early postoperative complication. This technique was found to be rapid, simple, and safe in children, especially neonates and infants.

Abstract:

In case of the need of pacemaker implantation, patients with artificial tricuspid valve are a special group of subjects, because of high risk of dysfunction of the prosthesis. In case of mechanical prosthesis of tricuspid valve the leads of pacemaker are usually located in coronary sinus. In case of biological prosthesis of tricuspid valve despite of the risk of prosthesis damage the electrodes are implanted endocardially. The leadless pacemakers seems to be promising alternative in patients with artificial tricuspid valve because of minor risk of valve damage. The case report concerns to the patient with tachycardia-bradycardia syndrome and biological prosthesis of tricuspid valve in whom the leadless pacemaker Micra was implanted.

Abstract:

Implantation of leadless pacemakers is associated with significantly fewer complications when compared to conventional pacemakers due to elimination of transvenous leads, which are among the weakest components of the pacing system. There are patients in whom implantation of a conventional transvenous pacemaker is very troublesome and problematic or associated with a higher risk of complications, including infectious, as a result of a very limited venous access or use of central veins for other purposes (for example haemodialysis or administration of drugs). We present two real life clinical cases as examples of potential indications for use of leadless pacemakers in everyday practice.

Abstract:

Permanent pacemaker implantation is considered for carotid sinus hypersensitivity with asystolic pause of >3 seconds during carotid sinus massage, with or without associated systolic blood pressure drop of >50 mmHg. Aims: To assess the outcome of treatment with dual chamber permanent pacemaker implantation for carotid sinus hypersensitivity in a district general hospital and to compare our practice with available national data. Methods: Patients presenting with syncope, dizziness or unexplained falls were initially assessed as outpatient and investigations, commonly cardiovascular were performed including tilt table test with carotid sinus massage to look for carotid sinus hypersensitivity, vasovagal syncope and postural hypotension. A retrospective analysis was performed on patients who had pacemaker implantations for carotid sinus hypersensitivity. Results: Fifty pacemaker implantations were performed, 14 (28%) were for carotid sinus hypersensitivity. Mean follow-up period was 10 months. Age range was 56–88 (mean = 71.9) years. In the eighteen months prior to pacemaker implantation, 71.4% of patients had syncope, 64%> dizziness and 50% had unexplained falls. Following pacemaker implantations, only 2 (14.3 %) had symptoms. Scottish national figures show 13.6% of all new pacemaker implants were for carotid sinus hypersensitivity, and in district general hospitals this was 16%. Conclusions: Health benefits for patients presenting with syncope dizziness and falls can be achieved by cardiovascular investigations including tilt table testing. We have shown carotid sinus hypersensitivity is successfully treated with pacemaker implantation in a district general hospital setting and this type of clinic has an impact on the rate and type of new pacemaker implantation.

Abstract:

Background: Leadless transcatheter pacemaker systems (TPS) have become a valuable alternative to transvenous pacemakers in selected indications. With the steadily increasing amount of TPS implantations performed worldwide, reports of periprocedural complications are likewise increasingly found in the literature but are still underreported. Case presentation: We report a case of a 75 year old male undergoing TPS implantation due to cardioinhibitory vasovagal syncope. The implantation was primarily uneventful; adequate pacing parameters and fixation of the device were achieved. Unfortunately, dislocation of the leadless pacemaker occurred at the end of the procedure and the device embolized into a primary side branch of the right pulmonary artery. Endovascular retrieval was performed by using a single snare technique without any further complications. Conclusions: Although challenging, endovascular recovery of embolized TPS from the pulmonary artery is feasible and may be successfully accomplished by experienced implanters.

Abstract:

In the following review article, the principles and approaches of medical rehabilitation in patients with implanted pacemakers are discussed. It was shown that total benefit results from cooperation among medical, physical and psychological components of rehabilitation program and optimisation of the mode and parameters of cardiac pacing. Social adaptation of the patients with implantable pacemakers is of paramount importance and should be directed on avoidance of external electromagnetic fields and their influence on pacemaker functions, which in turn may be life-threatening for patient and the staff as well. The indications to diagnostic and treatment regimens including physiotherapeutic procedures should be clearly defined in order to avoid potential influence of electromagnetic interference on cardiac pacemaker. The well-structured medical rehabilitation programs need to be organised in order to improve quality of life and patients survival with regard to growing tendency of implantation of cardiac pacemakers.

Abstract:

Pacing is currently the main method of treatment in children with life-threatening bradyarrhythmias. The high-grade atrioventricular block remains the main indication for permanent pacing in children. The factors that determine the specificity of device implantation in the pediatric population are as follows: anthropometric data of a child and their compliance with the size of a pacemaker and the electrodes, the need for long-term (lifelong) cardiac stimulation and multiple replacements of a pacemaker, high level of child’s activity, changes in the physical parameters of the body over time (the need for implantation of the leads “with reserve” and their replacement), and, in some cases, the presence of concomitant congenital heart defects, especially, with intracardiac shunts. One of the controversial issues in pediatric cardiac stimulation is choosing a method of implantation (epicardial or endocardial). According to recent reports, the epicardial lead implantation techniques are increasingly being used because the transvenous pacemakers are associated with more serious complications and due to the capability to choose hemodynamically optimal stimulation zone in epicardial technique to prevent pacemaker-induced dyssynchrony. This approach allows to ultimately postpone the implantation of the endocardial stimulation system, administration of which is associated with the problem of endovascular lead extraction in children, the problem, which has not been resolved not only in Russia but also worldwide. This review article discusses recent literature on the use of permanent pacing in children, including the advantages and disadvantages of using the endocardial and epicardial pacemaker systems as well as various methods of implantation and pacemaker modes most often used in pediatric practice.

AbstractObjectivesIn patients with CHD, cardiac MRI is often indicated for functional and anatomical assessment. With the recent introduction of MRI-conditional pacemaker systems, cardiac MRI has become accessible for patients with pacemakers. The present clinical study aims to evaluate safety, susceptibility artefacts, and image reading of cardiac MRI in patients with CHD and MRI-conditional pacemaker systems.Material and methodsCHD patients with MRI-conditional pacemaker systems and a clinical need for cardiac MRI were examined with a 1.5-T MRI system. Lead function was tested before and after MRI. Artefacts and image readings were evaluated using a four-point grading scale.ResultsA total of nine patients with CHD (mean age 34.0 years, range 19.5–53.6 years) received a total of 11 cardiac MRI examinations. Owing to clinical indications, seven patients had previously been converted from conventional to MRI-conditional pacemaker systems. All MRI examinations were completed without adverse effects. Device testing immediately after MRI and at follow-up showed no alteration of pacemaker device and lead function. Clinical questions could be addressed and answered in all patients.ConclusionCardiac MRI can be performed safely with high certainty of diagnosis in CHD patients with MRI-conditional pacemaker systems. In case of clinically indicated lead and box changing, CHD patients with non-MRI-conditional pacemaker systems should be considered for complete conversion to MRI-conditional systems.

Abstract:

Raigmore is a district general hospital offering a permanent pacemaker service to its catchment population of 233,500. This report reviews the pacemaker practice over a seven year period (1994 to 2000) and makes a comparison with the national database and other hospitals in the UK. The records of all patients receiving new implantions for the period under observation were reviewed retrospectively. Data collected included number of patients paced each year, age, sex, indications and complications. In the 84 months studied 3/71 patients received new permanent pacemakers (the mean age was 74 years and 51% were male). The most common presenting symptoms were syncope (62%), dizzy spells (24%), and heart failure (11.5%). The most common indication for permanent pacemaker insertion was complete atrioventricular block (58%) followed by sick sinus syndrome (20%). The implantation rate was 419.3/million population /year in 2000. Pacemaker modes used were appropriate and the early and late complication rates were low (2.7%). This current audit demonstrates continued growth of the service with low-complication rates and implantation rates which approach those in Western Europe and North America.

Abstract:

BACKGROUND: Many patients who are candidates for a pacemaker are also at the same time risk factors for coronary artery disease such as high blood pressure, hypertension, diabetes, and hyperlipidemia, and therefore the probability of having coronary artery disease is significant. Effective diagnostic measures can be taken to prove the factors affecting the incidence of CAD in patients undergoing pacemakers at high-risk, including angiography. Therefore, it can prevent complications during and after pacemaker implantation, which leads to an increase in the quality of treatment in patients requiring pacemaker implantation. AIM: Therefore, the purpose of this study was to determine the predictive factors of significant coronary artery disease in patients with pacemaker implantation to identify patients in need of coronary angiography at the time of pacemaker implantation. METHODS: This retrospective study was carried out to examine the patients' files that were placed at the heart of Imam Reza Hospital during the period between March 2017 and September 2017. Demographic data, risk factors, echocardiography findings, and angiography, were collected and then recorded using a checklist. Statistical analysis was performed using SPSS software version 22 and Chi-square, and Mann-Whitney tests were used for determining significates variables. RESULTS: A group of 102 patients who had undergone a permanent cardiac pacemaker insertion due to an atrioventricular (AV) Block were included in the study, and also coronary anatomy was determined coronary angiography. Based on the results, 13.7% of patients with cardiac pacemaker had obstructive coronary artery disease (stenosis > 70%). Factors affecting coronary artery stenosis on angiography include gender, chest pain, history of myocardial infarction, angioplasty, diabetes, smoking, history of aspirin intake, calcium blocker and Plavix, high hematocrit, ST elevation and ST depression in the ECG, and severe mitral regurgitation. CONCLUSION: It seems that in most patients requiring permanent pacemaker insertion because of the atrioventricular (AV) Block, angiography does not change the patient's fate, and so can be ignored. However, in patients who have several risk factors from the listed above, coronary angiography is recommended during admission.

Abstract:

Abstract Background A leadless pacemaker is a new concept in which a miniaturized pacing device is self-contained within the heart. Recently published data show that leadless pacemakers are associated with a decreased risk of major complications when compared with transvenous cardiac pacemakers. This seems to be of particular importance in children and young adults in whom various complications may occur during their lifetime. Case summary Herein, we report the successful implantation of Micra™ Transcatheter Pacing System in two children: 12-year-old boy and 13-year-old girl, along with a long-term follow-up. The children had indications for pacemaker implantation, however, with an expected low percentage of pacing due to paroxysmal nature of the third-degree atrioventricular block. The implantation procedures were performed in general anaesthesia. There were no complications. During the 2-year follow-up, there were no adverse events and the electrical parameters of the device remained stable. Pacing percentage was below 0.1%. Discussion Transvenous cardiac pacemakers improve quality of life and reduce mortality but may be associated with various short- and long-term complications, mainly related to the presence of transvenous leads and the pulse generator. Compared with adult patients, the implantation of conventional pacemakers in children is still a challenge, not only because of their smaller size but also due to continuing growth, as well as a higher rate of lead and device-related complications. We demonstrate that the implantation of leadless pacemakers in children is feasible and could be worth considering in certain clinical scenarios, especially when ventricular pacing is required rarely.

Abstract:

Vasovagal syncope (VVS) can occur in every third of human population. Clinical symptoms of VVS areas a result of arterial hypotension with critical global cerebral hypoperfusion due to vasodilatation and bradicardia. Bradicardia is manifested as sinus node dysfunction and atrioventricular conduction disturbances due to activation of nervus vagus. Asystole can take place in some cases. Lack of efficacy of permanent pacemaker founds in patients to prevent of VVS. The results of double blind placebo controlled studies, European and American expert's opinions, probable causes of lack of efficacy of pacemakers in such category of patients and way of solution of this problem are discussed in the review. Syncope recurrences in spite of pacemaker implantation, risk of surgery complications and good life prognosis are arguments for therapeutic approach, now suitable for the most of patients with VVS. Case report (VVS with asystole but without of pacemaker implantation) with successful follow-up is analyzed in the article.

Abstract:

Introduction Temporary transvenous pacemaker insertion is an emergency lifesaving procedure for patients with hemodynamically unstable and life-threatening bradyarrythmias. The aim of this study was to analyze demographics, indications, route of insertion and complications in patients undergoing temporary transvenous pacemaker implantation. MethodsThis was a retrospective observational study conducted at a tertiary-care center in Nepal. The hospital records of patients who had undergone temporary transvenous pacemaker implantation between July 2015 and June 2019 were reviewed. ResultsA total of 343 patients with mean age of 65.52±16.09 years received temporary transvenous pacing. Out of these 205 (59.8%) were males. Greater proportion of patients were between the age group of 70-80 years (n=76, 22.2%). Hypertension (n=97, 28.3%) was the most common comorbidity noted. The most common indication for temporary pacing was symptomatic complete heart block 165 (59.6%). Total of 288 (84%) patients received permanent pacemakers while 55(16%) had reversible cause so TPI was removed. Right Femoral vein was the most common (99%) venous access site. Among the 343 patients, complications were observed in 29 (8.4%) of cases during and after the temporary transvenous pacemaker insertion. The overall mortality stood low at 2% (n=7). ConclusionTemporary transvenous pacemaker insertion is required in elderly population presenting with bradyarrythmias and occasionally in acute myocardial infarction presenting with bradyarrythmias as complication. Temporary pacemaker insertion was overall a safe procedure with infrequent serious complications; however, strategies to avoid and alleviate such complications (RV perforation) should be sought and implemented.

Abstract:

Background Permanent pacemaker implantation after surgical aortic valve replacement depends on patient selection and risk factors for conduction disorders. We aimed to identify risk criteria and obtain a selected group comparable to patients assigned to transcatheter aortic valve implantation. Methods Isolated sutured aortic valve replacements in 994 patients treated from 2007 to 2015 were reviewed. Demographics, hospital stay, preexisting conduction disorders, surgical technique, and etiology in patients with and without permanent pacemaker implantation were compared. Reported outcomes after transcatheter aortic valve implantation were compared with those of a subgroup including only degenerative valve disease and first redo. Results The incidence of permanent pacemaker implantation was 2.9%. Longer hospital stay ( p = 0.01), preexisting rhythm disorders ( p < 0.001), complex prosthetic endocarditis ( p = 0.01), and complex redo ( p < 0.001) were associated with permanent pacemaker implantation. Although prostheses were sutured with continuous monofilament in the majority of cases (86%), interrupted pledgetted sutures were used more often in the pacemaker group ( p = 0.002). In the subgroup analysis, the incidence of permanent pacemaker implantation was 2%; preexisting rhythm disorders and the suture technique were still major risk factors. Conclusion Permanent pacemaker implantation depends on etiology, preexisting rhythm disorders, and suture technique, and the 2% incidence compares favorably with the reported 5- to 10-fold higher incidence after transcatheter aortic valve implantation. Cost analysis should take this into account. Often dismissed as minor complication, permanent pacemaker implantation increases the risks of endocarditis, impaired myocardial recovery, and higher mortality if associated with prosthesis regurgitation.

Abstract:

Background and Aims: Although pacemaker implantation has been done regularly in Nepal for the last 20 years, there is no large scale published data of pacemaker implantations. Manmohan Cardiothoracic Vascular and Transplant Centre (MCVTC) have been providing uninterrupted permanent pacemaker implantation services since its inception. This led us an opportunity to report the data regarding permanent pacemaker implantations in MCVTC. Methods: Hospital records of all patients who had undergone PPI at MCVTC between Shrawan 2070 – Ashad 2075/ July 2013- June 2018 (5 years) were searched for and all available data were retrospectively analyzed. Results: A total of 277 cases underwent PPI at MCVTC in 5 years. Out of these 165 (59.5%) were male with male to female ratio of 1.47. The mean age was 65.82±16.10 years with 3 (1.1%) cases of <20 years of age and almost 70% of cases aged >60 years. Dual chamber units were implanted in 49 (17.7%) cases. Only 13 women (11.6%) received dual chamber pacemaker compared with 36 men (21.8%) (P = 0.029). The most common indication for PPI was complete atrioventricular block 165 (59.6%) followed by sick sinus syndrome 65 (23.5%). Hypertension 84 (30.3%) was the most common co morbidity present. Complication occurred in 5.4% of cases with wound infection as commonest complication and single mortality due to postoperative complications post-RV repair. Conclusion: Single chamber pacemaker was the most commonly used pacemaker. Dual chamber pacemaker was more common in younger patients. Complete heart block was the most common indication. Permanent pacemaker insertion was effective and relatively safe procedure in MCVTC with few complications.

Abstract:

Introduction. Pacemakers are devices that modern medicine and cardiology cannot be imagined without. The technique of implantation comes to surgical procedure where all principles of asepsis and antisepsis have to be respected. Although some complications do happen, they are rather rare. Results. After the implantation of the device, the patient is not handicapped (unless the heart was additionally damaged). On the contrary, the patient returns to his work and functions normally within his family in most of the cases. The first medical appointment is scheduled a month after the implantation and the following are three and six months after. Types of devices. Today there are ?new types of electrostimulation?- implantable cardioverter defibrillators and multisite electrostimulators. The former is implanted in patients at high risk of sudden cardiac death and the latter in patients with heart failure and left bundle branch block. Owing to these devices, the sudden cardiac death can be prevented successfully and the quality of a patient?s life is improved.

Abstract:

Contents: Patients undergoing permanent implantable pacemaker, challenge with multiple physical, psychological along with social complications. Teaching patients the essential points involving pacemaker management can prevent complications. Aim: The current study aimed to evaluate the effect of an educational program on outcomes of patients undergoing permanent pacemakers' implantation. Methods: A quasi-experimental pre/posttest and follow-up design were used to conduct this study. A convenient sample of 35 adult patients from both genders undergoing permanent pacemaker implantation was recruited from Beni-Suef University hospital's catheter lab, inpatient department, ICU, CCU, and outpatient cardiology clinic. Patients' interviewing questionnaire, patient performance checklist, pacemaker self-efficacy scale, and Aga Khan University Anxiety and Depression Scale were used to achieve this study's aim. Results: 91.4% of the studied patients had unsatisfactory total knowledge at the baseline, improved to 85.7% had a satisfactory knowledge immediately post educational intervention, and relatively maintained to 68.6% of them had a satisfactory level of total knowledge after four weeks of program implementation. 97.1% of the studied patients had unsatisfactory total practice at the baseline, improved to 65.7% had a satisfactory practice immediately post educational intervention, and improved to 77.1% of them had a satisfactory level of total practice after four weeks of program implementation. 71.4%, 85.7% of the studied patients were not confident at all with their ability to control symptoms and maintain their usual functions respectively before education. 91.4% of them reported a total low self-efficacy score before the educational intervention. In comparison, 45.7% were very confident in controlling symptoms and moderately confident in maintaining usual functions at the follow-up phase. Besides, 65.7 exhibited total high self-efficacy at the follow-up assessment. 57.1% of the studied patients exhibit severe anxiety at the baseline assessment, while 65.7% and 74.3% exhibit mild anxiety at the post and follow-up assessment. Conclusion: A statistically significant improvement in patients' knowledge, practice, self-efficacy, anxiety, and depression immediately and after four weeks compared to their baseline. The study recommended that the educational program be an essential part of the total management of patients undergoing implanted pacemakers.

Abstract:

In Tayside region, from 1976 to 1986, the number of permanent pacemakers implanted per year more than doubled, with the increase particularly marked over the latter five years. In order to determine the factor(s) which had caused this increase in implantation rates, a retrospective analysis of patients undergoing pacemaker implantation during the period 1981–1986 was undertaken. No change in the number of elderly in the population, age of patients, mode of referral, waiting time before insertion or clinical indications for pacing was observed to account for this change. The advent of ambulatory ECG monitoring may have contributed to this increase, but the appointment of an extra cardiologist in Tayside in 1982 was believed to have been more important. These results suggest that the number of pacemakers implanted in a region is highly dependent on the number of cardiological staff in that region available for their insertion.

Full text

Abstract:

Leadless pacemakers will most likely be the future of cardiac pacing. Leadless pacing employs a single-chamber system to pace only the right ventricle and is fully self-contained, which eliminates the need for leads. These systems, implanted by using a transcatheter sheath, are indicated for patients who need right ventricular pacing only. These devices enable patients to avoid lead-related complications, from lead fracture to extraction challenges, as well as pocket-related complications such as infection and disfigurement. Leadless pacemakers also are compatible with magnetic resonance imaging and do not require surgical placement, so patients avoid postoperative mobility restrictions. Because this technology will be increasingly used for cardiac internal electronic devices, commonly seen in critical care nursing, nurses must be knowledgeable about the indications for use of a wireless pacemaker, the implantation procedure, postprocedural care, device interrogation, and follow-up. This article discusses leadless pacemakers, clinical indications for their use, key similarities and differences between the current devices being used, key points for nursing care of patients with a leadless device, and the future of this technology.

Abstract:

Subclavian vein puncture is a relatively fast and safe technique to access the right heart for placement of pacemaker leads. Hemothorax related to injury of the pulmonary artery (PA) is a rare complication of subclavian vein access but can be life-threatening. We report a case of hemothorax occurring after subclavian vein puncture for pacemaker implantation. No cases of transcatheter arterial embolization for PA injury secondary to pacemaker implantation have been reported. Understanding of this rare complication after pacemaker implantation along with its specific clinical presentation may lead to early diagnosis and intervention.

Abstract:

ObjectivesTo identify risk factors and to develop a predictive risk score for pacemaker implantation in patients with atrial fibrillation (AF).MethodsUsing Danish nationwide registries, patients with newly diagnosed AF from 2000 to 2014 were identified. Cox proportional-hazards regression computed HRs for risk factors of pacemaker implantation. A logistic regression was used to fit a prediction model for 3-month risk of pacemaker implantation and derived a risk score using 80% of the data and its predictive accuracy estimated using the remaining 20%.ResultsAmong 155 934 AF patients included, the median age (IQR) was 75 (65–83) and 51.3% were men. During a median follow-up time of 3.4 (1.2–5.0) years, 8348 (5.4%) patients received a pacemaker implantation. Risk factors of pacemaker implantation were (in order of highest risk first) age above 60 years, congenital heart disease, heart failure at age under 60 years, prior syncope, valvular AF, hypertension, ischaemic heart disease, male sex and diabetes mellitus. The derived risk score assigns points ranging from 1 to 14 to each of these risk factors. The 3-month risk of pacemaker implantation increased from 0.4% (95% CI: 0.2 to 0.8) at 1 point to 2.6% (95% CI: 1.9 to 3.6) at 18 points. Area under the receiver operator characteristics curve was 62.9 (95% CI: 60.3 to 65.5).ConclusionWe highlighted risk factors of pacemaker implantation in newly diagnosed AF patients and created a risk score. The clinical utility of the risk score needs further investigation.

Abstract:

Abstract Permanent pacemaker (PPM) implantation can lead to thromboembolic events at different times after the procedure. According to literature, 1.7% of patients with pulmonary embolism have an implantable cardiac device. This frequency is higher than reported so far, from 0.16 to 0.47% of the total population. The pathophysiologic mechanism of pulmonary embolism in chronic thromboembolic pulmonary hypertension (CTEPH) is multifactorial. Recently, there is evidence that not only the organisation of thrombotic deposits in the proximal pulmonary arterial vessels is important, but also the development of small vessel disease, which plays an important role in the evolution and progression of the disease. The role of thrombosis in medical devices in contact with blood flow, such as stents, vascular grafts, heart valves, has been well studied and documented in scientific literature on biomaterials. It is clear that implantable cardiac devices such as pacemakers, similarly to other foreign surfaces exposed to blood flow, promote blood clotting and complement activation. Numerous studies to date have addressed the potential risk of distal vascular involvement of pulmonary circulation in the presence of a pacemaker, but none has conclusively proven this hypothesis. Over the last decade, there has been significant progress in the therapeutic potential of CTEPH. Pulmonary endarterectomy remains the only therapeutic method that can lead to lasting clinical improvement in these patients while achieving a good quality of life. This method is operational, with high financial value and is associated with the presence of a highly specialised team of specialists. This justifies the search for ways to prevent the onset of the disease rather than treat the consequences.

Abstract:

We report a case of right ventricular wall perforation by a pacemaker lead in a 78-year-old female 18 days after a permanent pacemaker insertion. This injury necessitated explant of the perforating lead and implantation of a new one with surgical backup. We review the literature and discuss the possible risk and protective factors including lead models that were associated with higher incidence of perforation. We review the traditional pacing parameters and their lack of reliability to diagnose perforation and the need for low threshold to utilize imaging in appropriate clinical scenarios. The authors believe this case is of educational value to all health care professionals, especially emergency medicine and internal medicine residents, who routinely see patients with pacemakers complaining of chest pain, shortness of breath, or dizziness.

Abstract:

Abstract BACKGROUND Deep brain stimulation (DBS) is a treatment modality increasingly utilized in the management of neurological and psychiatric conditions. Neurosurgical technical considerations and contraindications have yet to be thoroughly characterized in the literature. The patient population for DBS includes many elderly patients with multiple comorbidities who require treatments and investigations that expose them to electromagnetic fields of varying strengths and durations, including other implanted electromodulatory devices. OBJECTIVE To determine if clinically significant interference arises between DBS and cardiac pacemaker systems. METHODS Here we audited 8 patients, mean age 72, with cardiac pacemakers and DBS implanted from 2007 to 2015. We investigated details of their neurological and electrocardiological treatment and progress and sought evidence for interference between the two systems. RESULTS We found no evidence of DBS dysfunction, and only one case of abnormal pacemaker interrogation 2 yr post-DBS implantation was found, which was thought to be secondary to a medication issue rather than neuromodulation interference. CONCLUSION Our research reassures the clinician that pacemakers and DBS systems do not appear to affect one another and provides guidance on minimizing possibility of this.

Abstract:

Background and objectives: Leadless pacemakers are less invasive but are as effective as conventional pacemakers and are increasingly implanted in elderly patients. However, the implantation procedure is sometimes challenging in patients with abnormal anatomy, particularly those with an enlarged right heart. We aimed to determine the right heart parameters that were associated with longer procedure times for leadless pacemaker implantation. Materials and Methods: Among 19 consecutive patients in whom Micra leadless pacemakers (Micra TPS, Medtronic, Minneapolis, MN) were implanted, the diameter and area of both the right atrium and right ventricle were measured by transthoracic echocardiography before the procedure. The right heart parameters that were associated with a procedure time > 60 min were investigated. Results: In the 19 patients (median 81 years old, 10 male) who underwent implantation of the Micra system, 6 (32%) required a procedure time > 60 min. Among the baseline right heart echocardiographic parameters, right atrial diameter and area were significantly associated with a procedure time > 60 min (odds ratio 11.3, 95% confidence interval 1.09–1.17, p = 0.042; and odds ratio 1.57, 95% confidence interval 1.05–2.34, p = 0.029, respectively) at a cutoff of 4.0 cm and 17.0 cm2, respectively. Conclusions: Patients with an enlarged right atrium may not be good candidates for leadless pacemakers given the longer procedure time, and conventional pacemakers should perhaps be recommended as an alternative.

Abstract:

Background: Cardiac pacemaker infections have increased globally due to increase in demand and lack of adequate knowledge about its significantly contributing risk factors. This study was therefore aimed to determine the prevailing causative microbes and risk factors of both single and dual chamber permanent pacemaker infections. Methods: This was a retrospective case control study. Cases were selected as culture positive swab, Temporary pacemaker wire or catheter were matched with three controls for each variable using chi square test. Multivariate regression analysis was done to determine risk factors. Results: Among 47 cases, 23.4% cases were infected by methicillin resistant staph aureus, 14.9% by methicilin susceptible Staphylococcus aureus, 10.6% by pseudomonas, 8.5% by escherichia coli and 6.4% by klebsiella. Temporary pacemaker/Central line placed >24 hours ago before permanent pacemaker implantation, remnant pacemaker leads, corticosteroid use, no antibiotic prophylaxis, diabetes, smoking and non-absorbable stitches had statistically significant association with permanent pacemaker infection using multivariate regression model analysis. Chronic obstructive pulmonary disease and non-absorbable stitches had a non-significant association. Conclusions: Temporary pacemaker/Central line placed >24hours before permanent pacemaker implantation, remnant pacemaker leads, corticosteroid use, no antibiotic prophylaxis, diabetes, smoking and use of non-absorbable stitches are risk factors for permanent pacemaker infection. Staph aureus is the most prevalent microorganism causing infection.Keywords: Causes; dual chamber; Infectison; permanent pacemaker; risk factor; single chamber.
