Abstract

<p>A 71-year-old woman underwent repair of a ventricular septal perforation due to myocardial infarction by the extended sandwich patch technique 5 years ago. She was discharged from the hospital without complications. During the follow-up period, a ventricular apical aneurysm was found on contrast-enhanced computed tomography and transthoracic echocardiography. Since the aneurysm had enlarged gradually and a thrombus was found in it, repairing surgery was indicated. The patient was initiated on cardiopulmonary bypass after dissection of the adhesions of the previous surgery, and a longitudinal incision was made on the left side of the left anterior descending artery under cardiac arrest to remove the aneurysm. A large amount of thrombus was found inside the aneurysm. The thrombus was removed, Dor surgery was performed with a circular Hemashield patch. Reports of ventricular apical aneurysm after myocardial infarction in a remote period are rare. It is necessary to perform surgical intervention as soon as possible to prevent free wall rupture as well as cerebral infarction.</p>
