Successful percutaneous intervention of proximal left anterior descending artery in a case of single coronary artery trunk

AbstractCongenital coronary anomalies are mostly asymptomatic, detected accidentally during invasive or non-invasive imaging. One of the least encountered of such anomalies is single coronary ostium. Considering the fact that the whole myocardium is perfused by a single coronary vessel, performing percutaneous coronary stenting is a challenge for interventional cardiologists with some authors even considering it as a contraindication. Here we present a rare case of single coronary artery as a result of terminal extension of right coronary artery from left circumflex artery, for whom successful balloon angioplasty and stenting of left anterior descending artery after myocardial infarction was done.
