Catheter-induced left main coronary artery dissection resulting in abrupt closure and cardiac arrest: successful stenting during resuscitation.

Catheter-induced left main coronary artery dissection is an uncommon but devastating complication of coronary angiography and percutaneous coronary intervention. We present a case of left main coronary artery dissection induced with a guide catheter, which resulted in acute occlusion and cardiac arrest. Survival and complete functional recovery were achieved with bailout stenting.
