Abstract

To assess the influence of aorto-coronary bypass grafting on surgical risk and short-term survival of patients with marked impairment of left ventricular (LV) function, we evaluated--among 435 patients who underwent coronary bypass surgery between January 1981 and December 1982--22 cases with: LV ejection fraction (EF) less than or equal to 0.35 (mean 0.27 +/- 0.06), LV end-diastolic pressure greater than or equal to 15 mmHg (mean 19.9 +/- 6.9 mmHg.), presence of three or more dysfunctional (hypokinetic or akinetic) segments on biplane LV angiography, three vessels disease in 90.1%. All patients but two had angina refractory to medical therapy. Operative mortality rate was 4.5%. Perioperative non fatal infarction rate was 9.1%. There were three late deaths. Mean duration of follow-up was 10.5 +/- 8.3 months with a survival of 81.8%. In the survivors we observed: dramatic improvement in respect to angina (94.5% are asymptomatic) and quality of life; exercise performance improvement (75% of patients have a functional impairment less than or equal to 30% at treadmill test); significant improvement in global and segmental LV function (mean echocardiographic EF 0.37 +/- 0.10, p less than 0.001). Because of relative low surgical risk and encouraging short-term results, aortocoronary bypass grafting can be performed even in patients with important LV disfunction, when associated with severe angina.
