Dual-catheter covered stenting: a novel approach to the treatment of large coronary artery perforations.

Coronary perforation is an infrequent but potentially devastating complication of coronary intervention. Treatment of a broad-based perforation usually requires emergent pericardiocentesis and thoracotomy. We present a novel approach to closure of > or = 1 mm diameter perforations using a dual-catheter covered stent technique.
