Surgical Ostioplasty of the Left Main Coronary Artery: An Alternative to Coronary Artery Bypass Grafting in the Treatment of Left Main Stem Isolated Ostial Stenosis—A Case Series

This study aims to demonstrate the use of surgical ostioplasty left main coronary artery as an alternative technique conventional bypass grafting for treatment stem-isolated ostial stenosis. From 2002 2021, five patients—three women (60%) and two men (40%)—presented with a history angina pectoris were diagnosed isolated stenosis ostia associated normal distal arteries. Pre-operative cardiac catheterization echocardiography performed aid in diagnosis. The patients submitted posterior approach using saphenous patch. There no hospital deaths or myocardial infarctions during post-operative period. mean cardiopulmonary time was 82 min (range, 70–95 min), aortic-clamp 62 55–75 min). average hospitalization 6.2 days 4–18 days). Patients arteries may be grafting, traditional this pathology.
