Coronary artery rupture and pseudoaneurysm formation resulting from percutaneous coronary angioscopy.
We describe a case in which coronary angioscopy was complicated by inability to deflate the device's occlusion balloon. Rapid over-inflation to rupture the balloon resulted in massive dissection of the artery, pseudoaneurysm formation, and ultimately coronary bypass. While the cause of failure of balloon deflation remains obscure, deliberate over-inflation to cause rupture may be hazardous.
