Coronary artery to pulmonary artery fistula with dual origin--embryological, clinical and surgical significance.
Coronary artery fistulae are rare anomalies encountered in 0.1-0.2% of angiographic series. We recently encountered a patient evaluated for mitral valve disease who incidentally had bilateral coronary artery fistulae detected on preoperative angiogram. These fistulae drained into the pulmonary artery. She underwent successful transpulmonary closure of the fistula along with mitral valve repair. We discuss the embryological basis of this anomaly and the clinical as well as surgical significance.
