INTRODUCTION
It is unusual for a ST-elevation myocardial infarction (STEMI) to be caused by a left main coronary artery (LMCA) aneurysm [1]. The pathogenesis of STEMI in aneurysms is perplexing, and its therapy is still debatable. Case studies have been used primarily to describe pharmacological therapy, percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), and hybrid approaches depending on the severity of coexisting coronary artery stenosis.
