Objectives: Coronary artery bypass grafting in patients with low ejection fraction (<35%) still remains a high-risk procedure due to its high mortality and morbidity. Off pump coronary artery bypass grafting surgery can be an alternative technique in these patients. The aim of this study is to find out the short-term outcome of the patients with low ejection fraction (<35%) after off pump coronary artery bypass grafting and to quantify any improvement in overall functional status.Methods: Low ejection fraction was confirmed preoperatively and the short-term outcome after off pump coronary artery bypass grafting was be determined by follow-up at the time of discharge, after 1 month of surgery and after 3 month of surgery.Results: Significant improvement in terms of CCS grade and NYHA class was observed specially in <35% ejection fraction group. While there was a significant change between preoperative and postoperative 3 month follow up of patients in <35% ejection fraction group which was observed through echocardiographic evaluation and clinical assessment. The overall mortality was 2 in number. This was comparable with other international publications.

“…3,4 These data suggest that CABG may improve prognosis in selected patients with coronary heart disease and severely impaired systolic function, and it is frequently performed on this patient population. 5 It is, however, associated with a modest increase in risk compared with patients with normal LV function, [5][6][7] with some older publications reporting extreme variations in outcome. Nevertheless, previous studies have primarily addressed early (inhospital and/or 30-day) outcome, with limited contemporary data regarding longer-term mortality and morbidity.…”

Background-There are few data regarding medium-term outcome of coronary artery bypass grafting (CABG) in patients with severe left ventricular (LV) systolic dysfunction, particularly in the modern era, and even less assessing preoperative factors that might identify patients at highest risk. Methods and Results-Three hundred seventy-nine consecutive patients with LV ejection fraction Յ35%, who underwent isolated first CABG between 1995 and 1999 were studied. Potential preoperative and perioperative predictors of outcome were recorded and patients followed-up for a median of 3.8 years. The primary study end-point was all-cause mortality. The 30-day, 1-year, and 3-year survival rates were 94.5%, 88%, and 81%, respectively. The independent predictors of mortality were preoperative estimated glomerular filtration rate (hazard ratio

“…Cases of patients with major left ventricular dysfunction who underwent conventional surgery for the revascularization of the myocardium have been analyzed at length 15,16 ; nevertheless, the few articles published comparing surgeries with and without CPB in patients with ejection fractions under 35% [17][18][19] , present a few important differences between the groups, and this may difficultate a clear evaluation of the results.…”

SummaryObjective: To assess off-pump myocardial revascularization in patients with significant left ventricular dysfunction.Methods: Four hundred and five patients with an ejection fraction less than 35% underwent myocardial revascularization without extracorporeal circulation. The procedure was performed with the aid of a suction stabilizer and the LIMA stitch. The distal anastomoses were performed first.Results: A total of 405 patients were evaluated whose mean age was 63.4±9.78 years. Two hundred and seventy-nine patients were men (68.8%). With regard to risk factors, 347 patients were hypertensive, 194 were smokers, 202 were dyslipidemic, and 134 had diabetes. Two hundred and sixty patients were classified as NYHA functional class III and IV. Twenty patients suffered from chronic renal disease and were under dialysis. Fifty-one underwent emergency surgery, and 33 had been previously operated on. The mean ejection fraction was 27.2±3.54%. The mean EuroSCORE was 8.46±4.41. The mean number of anastomoses performed was 3.03±1.54 per patient. Forty-nine patients (12%) needed an intra-aortic balloon inserted after induction of anesthesia, whereas 73 (18%) needed inotropic support during the perioperative period. As to complications, 2 patients (0.49%) had renal failure, 2 had mediastinitis (0.49%), 7 (1.7%) needed to be reoperated because of bleeding, 5 patients (1.2%) suffered acute myocardial infarction, and 70 patients (17.3%) experienced atrial fibrillation. Eighteen (4.4%) patients died. Conclusion
