COMPLETE MYOCARDIAL REVASCULARIZATION WITH LEFT-HEART BYPASS WITHOUT OXYGENATOR ON THE BEATING HEART

Background: Whereas the complete myocardial revascularization is neces sary in high risk group patients, the CABG procedure on the beating he art on circumflex artery still presents a dilemma. Methods: Between Ja nuary 1994 and September 1996, we performed complete myocardial revasc ularization with left heart bypass in 62 patients (54 male, 8 female, mean age: 57) who had absolute or relative contrindications for CPB. R esults: The hospital mortality was 3.2%, late mortality was 1.6%. Pero perative MT was seen in 2 patients (3.2%). The mean number of distal a nastomosis was 3.6 (ranged 2-6). Conclusion: Complete myocardial revas cularization on the beating heart can be performed by using left heart bypass (LHBP) without using an oxygenerator safely in high risk patie nts.
