Spontaneous closure of a type 3 coronary artery perforation after percutaneous coronary intervention.

Coronary artery perforation (CAP) is a rare, but potentially serious complication of percutaneous coronary artery intervention (PCI). The strategies for management of patients with CAP include prolonged balloon inflation, coil embolization, covered stent implantation, pericardiocentesis, urgent surgery and reversal of heparin with protamine sulfate. We would like to share a case of type 3 perforation of left anterior descending artery (LAD) occurred during PCI, giving rise to cardiac arrest and closed spontaneously after effective cardiopulmonary resuscitation.
