A rare case of acute myocardial infarction with multivessel coronary artery ectasia successfully treated with percutaneous coronary intervention and systemic thrombolysis

Abstract

Coronary artery ectasia (CAE) is defined as a coronary artery dilatation with a diameter ≥1.5 times greater than that of a normal adjacent artery. All 3 coronary vessels can be affected by CAE, but the incidence of multivessel CAE among patients undergoing coronary angiography is quite low. We herein report an extremely rare case of acute myocardial infarction due to massive thrombi in the giant right coronary artery with multivessel CAE. Thrombus aspiration during percutaneous coronary intervention may be limited in giant coronary artery cases, and systemic thrombolysis may be effective in patients with massive thrombi in the giant coronary artery.
