Complete myocardial revascularization with left heart bypass without oxygenator on the beating heart

Background:
Whereas the complete myocardial revascularization is necessary in high risk group patients, the CABG procedure on the beating heart on circumflex artery still presents a dilemma.
Methods:
Between January 1994 and September 1996, we performed complete myocardial revascularization with left heart bypass in 62 patients (54 male, 8 female, mean age: 57) who had absolute or relative contraindications for CPB.
Results:
The hospital mortality was 3.2%, late mortality was 1.6%. Peroperative MI was seen in 2 patients (3.2%). The mean number of distal anastomosis was 3.6 (ranged 2-6).
Conclusion:
Complete myocardial revascularization on the beating heart can be performed by using left heart bypass (LHBP) without using an oxygenerator safely in high risk patients.
