Large common left and right coronary artery to coronary sinus fistula

Abstract

Coronary fistulas are vascular anomalies which in rare cases can cause hemodynamic problems with indication for intervention. We report about a 47-year-old man with a large coronary fistula arising from both, the left and right coronary artery. To our knowledge this is the first case described with this anatomy. The main coronary arteries were united at the crux cordis and drained through the coronary sinus into the right atrium. As a consequence of the longstanding volume overload the coronary arteries were extremely dilated. Also, both ventricles were dilated. Therefore, although the patient was asymptomatic, the obvious compromise of the ventricles due to volume overload was regarded as an indication for surgical intervention. © 2006 Published by European Association for Cardio-Thoracic Surgery.
