Abstract:

AbstractBackground:Development of pulmonary arteriovenous fistulas in patients with cavopulmonary anastomosis may result in a significant morbidity. Although the use of bubble contrast echocardiography with selective injection into both the branch pulmonary arteries in identifying pulmonary arteriovenous fistulas has been increasing, the actual efficacy of this diagnostic modality has not been properly evaluated. Thus, this study aimed to assess the efficacy of bubble contrast echocardiography in detecting pulmonary arteriovenous fistulas in children with total cavopulmonary connection.Methods

Abstract:

In the strictest sense, do-not-resuscitate (DNR) status means that cardiopulmonary resuscitation should not be performed after death has occurred; all other medical interventions in line with a patient’s goals of care should be implemented. The use of transthoracic echocardiography (TTE) in patients with DNR status is unknown. Therefore, we aim to evaluate the utilization of TTE among patients with DNR status using this retrospective data analysis. A total of 16,546 patient admissions were included in the final study. A total of 4370 (26.4%) of the patients had a TTE during hospitalization; am

Abstract:

Abstract INTRODUCTION: The pathogenesis of infective endocarditis (IE) , a typical biofilm-associated infectious disease frequently caused by commensal or pathogenic bacteria, is mainly attributed to the formation of septic vegetations, which are fibrin-platelet complexes embedded with bacteria on heart valves detected by echocardiography. Patients with acute myeloid leukemia (AML) are prone to neutropenia, immunosuppression and central venous catheters leading to high rates of bacteremia. It has been postulated that despite high rates of bacteremia, patients with AML undergoing intensive chem

Abstract:

Abstract Background: Pulmonary hypertension (PHT) is an increasingly recognised complication of sickle cell disease (SCD), even in asymptomatic patients. Studies from the US have shown a prevalence of PHT of between 20–30% and this has been associated with an increased mortality. The prevalence of PHT in the UK sickle cell disease population is unknown. Method: We identified adult patients with a diagnosis of SCD (HbSS, HbSC, HbSB0thalassaemia and HbSB+ thalassaemia) who had screening for PHT using transthoracic echocardiography over a one year period. We compared the echocardiographic finding

Abstract:

Purpose: Residual ventricular septal defects (rVSDs) of small size are commonly seen on transesophageal echocardiography after surgical repair. This study aimed to determine the destiny of rVSD found on intraoperative echocardiogram. Methods: Patients undergoing surgical repair of VSD as the primary procedure with available intraoperative and discharge echocardiograms between 2007 and 2017 were reviewed. Presence of an rVSD on intraoperative echo triggered review of discharge echo and of subsequent follow-up echocardiograms. Results: One hundred four patients were analyzed. The mean age and we

The causes of neonatal hypoxemia are usually either pulmonary or cardiac pathologies. We report a case of a 2-month-old boy with oxygen dependency since birth. He would desaturate down to 88-90% whenever supplemental oxygen was weaned off. Initial screening echocardiograms described only a small atrial septal defect, thus lung disease was thought to be the aetiology. Eventually, a detailed echocardiogram and CT angiography revealed anomalous right superior vena cava (RSVC) draining into the left atrium (LA).

Abstract:

Parasternal and apical echocardiography images captured from different cross-sectional planes (short-axis and four chambers) convey significant information about the structure and function of infarcted Left Ventricular (LV) myocardium. Thus, features from these cross-sectional views of echocardiograms extracted using computer-aided techniques may aid in characterizing Myocardial Infarction (MI). Therefore, this paper proposes a new algorithm for automated MI characterization using features extracted from parasternal short axis and apical four chambers cross-sectional views of 160 subjects (80

Introduction: Cardiovascular disease is the first cause of death worldwide; in Uruguay it corresponds to 30%. Classical risk factors are: age, smoking, male gender, diabetes, hypertension, hyperuricemia and dyslipidemia. In the last decades, the increasing use of chemotherapy and radiotherapy in oncology have augmented cardiovascular side effects. The improvement in response and overall survival of hematologic patients allow a longer time to develop cardiovascular complications.

In order to study the role of echocardiography during its use, and to describe the morphologic variants of defects suitable for closure with this occluder, we evaluated all patients undergoing intended closure of an atrial septal defect with the Helex occluder. A combination of transthoracic, transesophageal, three-dimensional, and intracardiac echocardiography were used before, during, and after the procedure to characterize anatomy, assess candidacy for closure, guide the device
