Absence of the Left Main Artery with Separate Ostia of the Left Anterior Descending Artery and Circumflex from the Left Sinus Valsalva: A Case Report

摘要

Coronary artery anomalies are diagnosed in approximately 1% of patients who undergo coronary angiography (CAG). Several anomalies are life threatening but are generally asymptomatic and clinically insignificant. Nonetheless, proper recognition and adequate visualization is necessary for proper medical management, especially in patients undergoing percutaneous coronary intervention or cardiac surgery. In this report, a 73-year-old female was admitted for NSTEMI. Coronary angiography revealed a stenotic right coronary artery and separate ostium of the left circumflex artery and left anterior descending artery from the left Valsalva sinus. The patient was treated with percutaneous coronary intervention of the RCA lesion.
