Surgical Ostioplasty for Isolated Ostial Stenosis of the Left Main Stem Coronary Artery

摘要

We report the cases of 4 patients in whom surgical ostioplasty was performed for isolated severe ostial stenosis of the left main stem coronary artery. No perioperative death or myocardial infarction occurred. One patient required reoperation for symptomatic recurrent ostial stenosis after 6 months. The others remained angina free after a mean follow-up of 23 months. The literature associated with this procedure is briefly reviewed.
