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. © 1993 Wiley‐Liss, Inc.
