Unusual Case of Anomalous Coronary Origin and Myocardial Bridge to Right Ventricle Communication

Anomalous coronary artery origin is rare and can occur with myocardial bridging. We describe a 28-year-old patient with symptomatic anomalous right coronary artery arising from the left sinus of Valsalva with concomitant myocardial bridging of the left anterior descending artery. It was discovered that the left anterior descending artery ran along the free right ventricular wall with trabeculated myocardium composing the bridge. To address this, the trabecular sinuses were unroofed, and the resulting free edge of the right ventricular wall was sutured back to the interventricular septum.
