Left Ventricular Pseudoaneurysm After Sandwich Patch Repair via Right Ventriculotomy for Postinfarction Ventricular Septal Perforation

Abstract

This report describes 2 rare cases of left ventricular pseudoaneurysm (LVPA) after sandwich patch repair through a right ventriculotomy for postinfarction ventricular septal perforation. The first case involved an 80-year-old man who experienced LVPA 8 months after undergoing the procedure. The second case involved a 63-year-old man with LVPA that was diagnosed incidentally 3 years postoperatively. In both cases, a large tear was observed along the previous anterior left ventricular wall suture line, and it indicated insufficient infarct exclusion at the patch repair site. Each patient successfully underwent patch repair.
