A covered coronary artery stent can potentially be used to seal coronary artery perforations, offering an alternative to emergency cardiac surgery.

May offer bailout for coronary perforations; hypothesis-generating and requires prospective validation before practice change.
Coronary artery perforation is an unusual but well recognised complication of Percutaneous Transluminal Coronary Angioplasty (PTCA) and coronary atherectomy and may lead to hemopericardium and cardiac tamponade. If the perforation cannot be sealed by prolonged inflation with a perfusion balloon catheter, emergency cardiac surgery is usually necessary. This case report describes the potential use of a "covered" coronary artery stent for sealing perforations in the coronary circulation.
