Outcome of Intracoronary Shunt in Off-pump Coronary Artery Bypass Surgery in Patients with Low Cardiac Output

Patients with coronary artery disease and left ventricular dysfunction have high mortality with non surgical (medical) treatment. Coronary artery bypass grafting improves survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study was to survey the result of coronary artery bypass grafting with off pump technique using intracoronary shunt in patients with left ventricular ejection fraction≤ 25%. From January 2009 to December 2012, 86 patients with an ejection fraction ≤ 25% (58 males, 28 females) aged 41- 84 years (61.2 ± 3.1 yrs) underwent coronary artery bypass graft surgery with off-pump technique. Grafting was performed as needed with internal mammary artery and saphenous vein. We studied operative and postoperative data. Hospital Mortality was 2.32% (two patients). Postoperative complications were low. Total length of hospital stay was 7.2 days, length of ICU stay 2.1 days pulmonary complications 3.48% (three patients), postoperative bleeding 340, acute renal failure 1.16% (onepatient) and left-ventricle ejection fraction before discharge was increased about 10% in these patients. Coronary artery bypass grafting without cardiopulmonary bypass with intracoronary shunt in patients with severe left ventricular dysfunction is valid and safe and has low mortality and morbidity.
