Coronary artery perforation repair using microcoil embolization.

An 82-year-old woman undergoing percutaneous transluminal coronary angioplasty experienced perforation of the terminal portion of the left anterior descending coronary artery caused by guidewire trauma. The coronary artery perforation was successfully closed using a vascular occlusion system consisting of individual thrombogenic coils delivered to the site. Coronary artery perforation (CAP) during percutaneous transluminal coronary angioplasty (PTCA) has been reported to occur in less than 1% of cases. The incidence seems to be higher with the new interventional devices, e.g., DCA, TEC, and laser CAP may result in pericardial hemorrhage and cardiac tamponade or a coronary artery fistula to either the left or right ventricle. The management of CAP may include prolonged balloon inflations, reversal of anticoagulation, pericardiocentesis, and emergency surgery. Proximal perforations sometimes can be managed with vein covered stents. We describe another option in the treatment of distal CAP using a vascular occlusion system.
