Coronary artery perforation in a patient with STEMI and a myocardial bridge: an increased risk for coronary artery perforation?

Cardiovasc Revasc Med. 2015 Jun;16(4):246-8. doi: 10.1016/j.carrev.2015.03.004. Epub 2015 Mar 21.

Abstract

We present the case of a patient with ST-elevation myocardial infarction (STEMI) due to subtotal occlusion of the left anterior descending coronary artery caused by an atherosclerotic lesion and a myocardial bridge (MB). Stenting of the MB caused coronary artery perforation resulting in a fistula to the right ventricle that was closed by implantation of a PTFE-covered stent. Follow-up coronary angiography showed persistent shunting, which was sealed by inflation of a high-pressure balloon over the site of extravasation guided by intravascular ultrasound. Additionally, we provide a short review of cases with coronary artery perforation after stenting of an MB.
