[Coronary lesions due to aortic valve disease. II -- Results and indications of aortocoronary bypass surgery].
454 cases of aortic valve replacement were studied: 217 had no significant coronary artery disease, 197 had associated aorto-coronary bypass surgery and 40 coronary artery disease without revascularization surgery:-- The early mortality in the three groups was 5.5%, 21% and 12.5% respectively, the only statistically significant difference being between the first two groups. -- The coronary artery disease was signigicantly more severe in the group which underwent associated aorto-coronary bypass surgery. The early mortality was significantly raised in the group without bypass surgery in cases with severe coronary artery disease (28%) and in the group with bypass surgery with unsuitable coronary artery lesions (35.5%). On the other hand, the long term survival and functional capacity of patients who underwent associated bypass surgery approached that of the non-coronary patients. Combined aortic valve replacement and coronary bypass surgery should therefore be continued in selected cases.
