Acute myocardial infarction in a young adult patient with simultaneous total occlusion of double coronary arteries

We report an otherwise healthy 16-year-old male patient with simultaneous double vessel acute myocardial infarction. Coronary angiography (CAG) showed simultaneous total occlusion of the left anterior descending artery (LAD) and the left circumflex artery (LCX). Emergent percutaneous coronary intervention (PCI) was performed on the diseased lesions. After PCI, coronary artery aneurysms were found in both the LAD and LCX. The patient was discharged after a 56-day hospitalization. The New York Heart Association (NYHA) Functional Classification at discharge was II. Medical therapy became ineffective over time because of exacerbated ischemic mitral regurgitation; successful mitral annuloplasty was performed. The post-operative course was uneventful.
