Surgical Angioplasty of the Left Main Coronary Artery with Venous Patch: Antegrade Myocardial Revascularization
Surgical angioplasty for severe stenosis of the left main coronary artery was performed with venous patch on seven patients. Surgical indication was elective in six of the seven cases. One patient who had had aortic and mitral valve replacement (5 months previously) required emergency surgery because of severe unstable angina and recent anterior myocardial infarction. Only one patient of this series necessitated another operation 6 months later with grafts using both internal mammary arteries for a new critical stenosis corresponding to a calcific plaque not removed during previous surgery. Operative indications are discussed as well as the angioplasty technique as an alternative to aortocoronary bypass surgery for left main coronary stenosis without peripheral lesions.
