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

P Schanzenbächer, J Bauersachs

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.
