Coronary fistula as an unusual cause of angina in a middle-aged man

Coronary artery fistulas are rare congenital anomalies, most often discovered as an isolated murmur during examination, typically discovered during childhood. We report the case of a middle-aged black man presented with angina pectoris and found to have a large coronary fistula between the left main stem and the right ventricle. The fistula was occluded using transcatheter coils. © 2007 Springer Science+Business Media, LLC.
