[Myocardial revascularization without extracorporeal circulation in patients with ischemic impaired left ventricular contraction].

Coronary bypass graft procedures still remain a surgical challenge in patients with severe left ventricular dysfunction. The study was designed to compare off pump myocardial revascularization with conventional bypass procedures in patients with ejection fraction below 35%. Our results suggest that in selected patients off pump bypass procedure, may be used as a suitable and safe alternative to conventionalon pump coronary surgery, permitting complete revascularization with comparable short-term results.
