Resumen:
Left main coronary artery aneurysm is an extremely uncommon coronary pathology that can present with angina, myocardial infarction, pericardial tamponade, or sudden death, and whose treatment still remains controversial. Here, we present a 64-year-old woman admitted due to angina with a previous mitral and aortic valve replacement. Transthoracic echocardiogram revealed an aortic prosthesis dysfunction and preoperative angiogram showed a large left main coronary artery aneurysm. Surgical aneurysm exclusion with concomitant coronary artery bypass grafting and aortic prosthesis replacement were performed after defining the aneurysm's anatomical details and relationship using contrast-enhanced computed tomography.
