Repair of ventricular septal perforation with asymmetrical conical patch exclusion.

We report a case of repair of the postinfarction ventricular septal perforation (VSP), using an equine pericardium tailored in an asymmetrical conical shape for exclusion (modified sack technique) and an additional direct patch closure of VSP. An asymmetrical conical patch is easily sutured to the normal septum away from the VSP edge by using the longer part of the cone border. The postoperative left ventriculogram 1.5 months after surgery revealed a minor leakage from the patch to the excluded left ventricle. However, no residual left to the right shunt was found in calculation from the oxygen saturation in blood samples. Echocardiography 1 year after surgery showed no residual patch leakage at all. We suggest that this modified sack technique is a simple and easy method by which to exclude the VSP.
