[Is aortocoronary bypass indicated in patients with lesions of the common trunk of the left coronary artery incapable of complete revascularization?].

Abstract

Obstructive lesions of the left common coronary trunk need surgery if our operability criteria: possibility of at least making a by-pass on the left descending anterior coronary branch and a not seriously compromised miocardial contractility exist. Of the 25 patients operated, there was a mortality of 8% and 3 intra-and post-operatory infarcts; two other patients died after some time (one for extracardiac causes). Other infarcts were not observed. 48% of the patients had incomplete riva-scolarization which after some time had an effect on the objective state of the patients but not on their survival. The authors conclude their studies by affirming that total surgical correction is indicated even on non susceptible patients on the basis of coronarography.
