[Coronary artery bypass grafting without cardiopulmonary bypass in 200 patients].
J Cardiol. 2000 Aug; 36(2):85-90.JC

Abstract

OBJECTIVES

To evaluate the efficacy of off pump coronary artery bypass grafting (CABG), results in the initial consecutive 200 patients were reviewed.

METHODS

Between October 1996 and December 1999, 200 patients underwent CABG without cardiopulmonary bypass. There were 146 men and 54 women aged from 27 to 89 years (mean 68 years). Single, double, triple and left main disease were noted in 94, 55, 33 and 18 patients, respectively, with a mean ejection fraction of 51%. Preoperative complications were previous stroke in 34 patients, chronic renal failure in 22 patients, previous CABG in 18 patients, and aortoiliac aneurysm or occlusive disease in 14 patients. Fifty-five patients (28%) were 75 years or older. Surgical approach was made through a midsternal incision including lower half small sternotomy in 105 patients, left anterior small thoracotomy in 92 and small epigastric incision (gastroepiploic-right coronary anastomosis) in 3. Mean number of distal anastomoses was 1.3 (range 1-4). Anastomosis was performed in 189 left anterior descending, 13 diagonal, 27 circumflex and 41 right coronary arteries. The conduits were 174 internal thoracic, 10 internal thoracic-inferior epigastric composite, 22 right gastroepiploic and 5 radial arteries, and 50 saphenous vein grafts. Four patients underwent combined off pump CABG and transmyocardial laser revascularization, and 36 patients underwent hybrid (off pump CABG and angioplasty) revascularization.

RESULTS

Four patients (2.0%) died in the hospital due to intestinal necrosis in 2 patients, postoperative aortic dissection in one, and multiorgan failure with stroke in one. No serious ventricular tachyarrhythmia or use of intraaortic balloon pump occurred. Perioperative myocardial infarction was noted in one patient. Stroke occurred in 4 patients (2.0%) but 3 patients recovered in a short period. Three-year survival and cardiac event free rate were 90.3% and 81.1% by the Kaplan-Meier method. Postoperative angiographic study showed excellent patent graft in 92% of grafts (192/209), stenosed (> or = 50%) graft in 5% (10/209) and occlusion in 3% (7/209).

CONCLUSIONS

Off pump CABG can be performed safely and effectively in both high risk and low risk patients with coronary artery disease. Refinement of surgical technique and equipment will make this procedure more useful.
