Giant pseudoaneurysm that developed seven years after surgical repair of a postinfarction ventricular septal defect

Left ventricular pseudoaneurysm is a rare complication after myocardial infarction or cardiac surgery. An 88-year-old woman who developed a left ventricular pseudoaneurysm 7 years after the repair of a postinfarction ventricular septal defect was admitted to our hospital with a complaint of a pulsatile epigastric mass, which had persisted for a month. Enhanced computed tomography revealed a large left ventricular pseudoaneurysm that extended to the subcutaneous epigastric tissue through the supra-diaphragmatic space. Dehiscence of the patch on the lateral side, which was used during previous surgery, provided the entry site. Surgical repair with aneurysm exclusion patch plasty was successful, and the patient was discharged without any complications.
