Formation of a coronary artery aneurysm after inflation of a PercuSurge GuardWire distal protection balloon.
Formation of aneurysms in the coronary arteries with the use of the PercuSurge distal protection system has not been reported. We describe a 54-year-old man with acute myocardial infarction who was treated with the PercuSurge system. Angiography performed 2 weeks later revealed an aneurysm in the area of inflation of the distal protection balloon.
