Abstract:
ObjectivesUpdated knowledge about perioperative myocardial ischaemia (MI) after coronary artery bypass grafting (CABG) and treatment of acute graft failure is needed. We analysed main factors associated with perioperative MI and effects of immediate coronary angiography-based treatment strategy on patient outcome.MethodsAmong 1119 consecutive patients with coronary artery disease who underwent isolated CABG between January 2011 and December 2015, 43 (3.8%) patients underwent urgent coronary angiography due to suspected perioperative MI. All the data were prospectively collected and retrospectively analysed. The primary endpoint was 30-day mortality; postoperative left ventricular ejection fraction) and major adverse cardiac events were secondary endpoints.ResultsOverall, 30-day mortality in patients with CABG was 1.4% while in patients who developed perioperative MI was 9% (4 patients). Angiographic findings included incorrect graft anastomosis, graft spasm, dissection, acute coronary artery thrombotic occlusion and ischaemia due to incomplete revascularisation. Emergency reoperation (Redo) was performed in 14 (32%), acute percutaneous coronary intervention (PCI) in 15 (36%) and conservative treatment (Non-op) in 14 patients. Demographic and preoperative clinical characteristics between the groups were comparable. Postoperative LVEF was significantly reduced in the Redo group (45% post-op vs 53% pre-op) and did not change in groups PCI (56% post-op vs 57% pre-op) and Non-op (58% post-op vs 57% pre-op).ConclusionsUrgent angiography allows identification of the various underlying causes of perioperative MI and urgent treatment when this is needed. Urgent PCI may be associated with improved clinical outcome in patients with early graft failure.

Abstract:
Abstract Background Perioperative hypothermia is not uncommon in surgical patients due to anesthetic-induced inhibition of thermoregulatory mechanisms and exposure of patients to cold environment in the operating rooms. Core temperature reduction up to 35°C is often seen in off-pump coronary artery bypass graft (OP-CABG) surgery. Anesthetic depth can be monitored by using bispectral (BIS) index. The present study was performed to evaluate the influence of mild hypothermia on the anesthetic depth using BIS monitoring and correlation of BIS with end-tidal anesthetic concentration at varying temperatures during OP-CABG. Materials and Methods In a prospective observational study design in a tertiary care teaching hospital, patients who underwent elective OP-CABG under endotracheal general anesthesia, were included in the study. Standard technique of anesthesia was followed. BIS, nasopharyngeal temperature, and end-tidal anesthetic concentration of inhaled isoflurane was recorded every 10 minutes. The BIS was adjusted to between 45 and 50 during surgery. Results There were 40 patients who underwent OP-CABG during the study period. The mean age was 51.2 ± 8.7 years, mean body mass index 29.8 ± 2.2, and mean left ventricular ejection fraction was 55.4 ± 4.2%. Anesthetic requirement as guided by BIS between 45 and 50 correlated linearly with core body temperature (r = 0.999; p < 0.001). The mean decrease in the body temperature at the end of 300 minutes was 2.2°C with a mean decrease in end-tidal anesthetic concentration of 0.29%. The reduction in end-tidal anesthetic concentration per degree decrease in temperature was 0.13%. None of the patients reported intraoperative recall. Conclusion In this study, BIS monitoring was used to guide the delivery concentration of inhaled anesthetic using a targeted range of 45 to 50. BIS monitoring allowed the appropriate reduction of anesthetic dosing requirements in patients undergoing OP-CABG without risk of awareness. There was a significant reduction in anesthetic requirements associated with reduction of core temperature. The routine use of BIS is recommended in OP-CABG to titrate anesthetic requirement during occurrence of hypothermia and facilitate fast-track anesthesia in this patient population.

Abstract:
Abstract Background and Objectives Measurement of cardiac output (CO) during off-pump coronary artery bypass grafting (OP-CABG) is useful to assess the impact of displacement of heart during surgery. FloTrac uses the pulse-contour analysis algorithm to derive stroke volume (SV) and CO. This study was aimed to determine whether the site of monitoring of arterial pressure influences the CO measurement using Flotrac/Vigileo. Methods The authors recorded 75 sets of observations in 15 patients who underwent elective OP-CABG. Each patient had the radial and femoral artery cannulated and connected to FloTrac/Vigileo. The hemodynamic parameters were monitored at specified points of time intraoperatively. Results The CO, cardiac index, SV, stroke volume index, and stroke volume variation measured from radial artery did not differ from those of femoral artery at all points of measurement. Conclusion Either of the sites of monitoring of arterial pressure (namely radial and femoral artery) is acceptable for monitoring CO during OP-CABG.

Abstract:
Purpose: To evaluate the clinical impact of pleurotomy during skeletonized internal thoracic artery (ITA) harvesting in patients undergoing on-pump coronary artery bypass grafting (CABG). Methods: Consecutive patients (n = 758) who underwent CABG with skeletonized ITA were divided into 2 groups according to pleural integrity: open pleura (OP) and closed pleura (CP). Propensity score matching was performed after retrospective data extraction. The measured outcomes were postoperative pulmonary and hemorrhagic complications, 30-day mortality, and duration of hospital stay. Results: Among 236 propensity score–matched pairs, there was no statistically significant difference between the 2 groups in terms of first 30-day mortality (OP, n = 7 [3%]; CP, n = 5 [2.5%]), blood product use (OP, 0.90 ± 0.71; CP, 0.74 ± 0.7), or median duration of hospital stay. The incidence of postoperative pleural effusion, thoracentesis, prolonged mechanical ventilation, respiratory failure, excessive drainage, cardiac tamponade, and reexploration and the number of patients requiring transfusion were similar in both groups. Conclusion: The clinical effect of pleural protection or pleurotomy on postoperative outcomes is limited in patients undergoing on-pump CABG with skeletonized ITA.

Abstract:
Abstract It has been demonstrated that neutrophils activate macrophages via the heparin binding protein, thus possibly contributing to the incidence of heparin induced thrombocytopenia (HIT). It would follow that the incidence of thrombocytopenia and its sequelae may be reduced by using leukoreduced blood in patients undergoing cardiac bypass surgery. We had a unique opportunity to study this hypothesis at our institution. Due to a policy change all patients undergoing cardiac bypass surgery received LR blood intra-operatively prior to April 2005. Subsequent to this period non-LR blood was utilized in all patients. A retrospective chart review of 197 non-LR and 316 LR patients was done. The platelet count on admission, the first five days post- op, the day of discharge, the percent drop in platelet count post-op and heparin antibody (HA) test were obtained. Thrombocytopenia was defined as an overall drop in platelet count by > 50%. The CABG and the non-CABG patients were looked at separately. The results are as follows: Percent of patients with > 50% drop in platelet count: all patients CABG patients non-CABG patients leukoreduced arm 64% 62.4% 73.3% non-leukoreduced arm 64.6% 61.7% 82.1% Fisher’s exact test p = 0.92 p = 0.92 p = 0.57 Percent of patients with heparin antibody positivity: all patients CABG patients non-CABG patients leukoreduced arm (n=81) 24.7% 23.3% 28.6% non-leukoreduced arm (n=39) 30.8% 35.5% 12.5% Fisher’s exact test p = 0.51 p = 0.23 p = 0.63 In both the LR and non-LR populations there is only a 0.6% difference in the number of patients with a > 50% platelet drop. The relative risk is 1.01 with the 95% confidence interval of (0.88, 1.15). This is a relatively narrow confidence interval reflective of the relatively large sample size. Heparin antibody testing was not done on all the patients. Only those with persistent or profound thrombocytopenia had the test ordered. Overall heparin antibody positivity in both cohorts was not statistically different. The LR arm had a slightly higher positivity rate overall. The risk ratio is 1.25 indicating that the non-LR arm is 25% more likely to have a positive antibody test compared to the LR arm. The higher positivity rate in non-CABG patients may be due to the more complex nature of the surgery relative to CABG surgery. The non-CABG group has a higher percent of heparin antibody positivity in the LR arm. This inconsistency may be secondary to the smaller sample size of this group. In both the CABG or non-CABG groups, there was no statistically significant difference in the percent platelet drop or heparin antibody positivity. One can conclude that leukoreduction of red blood cell products during cardiac surgery does not significantly impact on thrombocytopenia or the development of HIT.

Abstract:
Fortgeschrittene koronare Herzerkrankungen können sowohl kardiologisch-interventionell als auch chirurgisch-invasiv behandelt werden. Unsere Autorin beschreibt eine chirurgisch relevante Therapieoption, die Koronararterien-Bypass-OP (englisch: coronary artery bypass grafting, kurz CABG) und gewährt dabei einen Blick hinter die Kulissen des Deutschen Herzzentrums Berlin (DHZB). Anhand des prüfungsrelevanten Erwartungshorizonts der Praxisanleiter des DHZB wird erläutert, wie mit körpereigenen Gefäßen die Engstelle im Herzkranzgefäß überbrückt und somit eine bessere Perfusion (Durchblutung) des Herzens wiederhergestellt wird.

Abstract:
A 43-year-old male, with no previous history of mental illness, was diagnosed with coronary heart disease, after which he became acutely depressed and attempted suicide by ingesting an organophosphate pesticide. He was admitted to an intensive care unit and treated with pralidoxime, atropine, and oxygen. His coronary occlusion pattern required early coronary artery bypass grafting (CABG) surgery. His family, apprehensive of a repeat suicidal attempt, requested surgery be performed as soon as possible. He recovered well from the OP poisoning and was mentally fit to express informed consent 2 weeks after admission. Seventeen days after poisoning, he underwent coronary artery bypass grafting and recovered uneventfully. Six years later, he remains in excellent health. We report this case because to the best of our knowledge there is no literature regarding CABG performed soon after organophosphate poisoning.

Abstract:
Die koronare Herzkrankheit ist trotz wachsendem Lebensstandard und aller präventiven medizinischen Maßnahmen nach wie vor von hoher medizinischer und ökonomischer Bedeutung. Die Akutform stellt das akute Koronarsyndrom dar. Komplizierend kann sich im Rahmen eines akuten Koronarsyndroms ein kardiogener Schock manifestieren, welcher die häufigste Todesursache für Patienten mit akutem Myokardinfarkt nach Aufnahme ins Krankenhaus darstellt. Ziel dieser Arbeit war die Identifizierung von Risikofaktoren für die Krankenhaus- sowie Langzeitmortalität bei der chirurgischen Revaskularisation von Patienten mit akutem Koronarsyndrom und komplizierendem kardiogenen Schock. Wir führten hierfür eine retrospektive Datenanalyse an 302 konsekutiven Patienten durch, welche im akuten Koronarsyndrom und kardiogenen Schock mittels aortokoronarer Bypassoperation therapiert wurden. Insgesamt wurden 44 präoperative, 18 intraoperative und 28 postoperative binäre Items analysiert. Wir konnten zeigen, dass bei den Höchstrisiko-Patienten die Letalität stark vom präoperativen Risikoprofil und dem Ausmaß des kardiogenen Schocks abhängt. Insbesondere der präoperative Einsatz einer IABP sowie die Verwendung der linken Arteria mammaria als Bypassgefäß wirkten sich positiv aus. Das gute Langzeit-Ergebnis demonstriert den Benefit einer chirurgischen Revaskularisation bei den Patienten mit akutem Koronarsyndrom und kardiogenen Schock mit anderenfalls schlechter Prognose.
