Left ventricle Subepicardial aneurysm following asymptomatic myocardial infarction

An asymptomatic 75-year-old female with past medical history of percutaneous coronary intervention for angina pectoris was referred to our department for the management of left ventricular aneurysm which was pointed out on the follow-up echocardiography. Coronary angiography revealed no restenosis of the stent site, but 100% stenosis of a distal segment of the left circumflex artery that had not been detected previously. Transthoracic echocardiography indicated a defect of the myocardium 2cm in diameter in the posterior wall Aneurysmectomy and patch closure was performed successfully before rupture and the lesion was diagnosed as subepicardial aneurysm.
