“Ostial Lesion of the Left Main Coronary Artery: PCI vs. CABG?"—A Case Report and Literature Review

For many years, coronary artery bypass grafting has been the primary method for revascularizing significant left main coronary artery disease. However, recent advancements in percutaneous coronary intervention with drug-eluting stents have proven to be a viable and effective alternative to coronary artery bypass grafting for treating this condition. In this report, we present a case of a patient with ischemic heart disease and severe left ventricular dysfunction. Coronary angiography revealed a lesion at the ostial left main coronary artery. Following successful primary angioplasty and the placement of a drug-eluting stent, the patient’s left ventricular ejection fraction significantly improved from 26% to 59%, indicating a significant enhancement in cardiac function post-procedure.
