Acquired right coronary artery fistula draining to the right ventricle: angiographic documentation of first appearance following reperfusion after acute myocardial infarction, with subsequent spontaneous closure.

Most coronary artery fistulae are congenital in origin but have been reported to be acquired as complications of chest trauma, coronary angioplasty, or rupture of a coronary artery aneurysm. This is the first angiographic documentation of a coronary fistula acquired after myocardial infarction that subsequently closed spontaneously during follow up.
