ABSTRACT
We describe a new technique for the early surgical repair of a posterior postinfarction ventricular septal perforation (VSP) in two consecutive female patients. The occurrence of a posterior VSP is rare, and its repair is technically difficult because the posteromedial papillary muscle is located adjacent to the intraventricular septum. This modification appears to prevent leaks to the right ventricle through the VPS with a single direct patch and the use of two equine pericardial patches to form a single endocardial pouch. The women were 77 and 62 years old, and the time between the onset of acute MI and surgery was 3 and 6 days. On preoperative catheterization, Qp/Qs was 4.18 and 4.01. Neither operative death nor residual shunting was observed.
