Postinfarction Inferior Ventricular Septal Rupture: Surgical Repair Through the Right Atrium

Abstract   Operative mortality of inferior postinfarct ventricular septal rupture (VSR) remains high. Previous reports have described a transatrial approach to access the VSR avoiding a ventriculotomy, thereby reducing the potential risks of myocardial damage, hemorrhage, and ventricular arrhythmias. The transatrial right ventricular patch or direct suture repair, however, is exposed to the left-to-right pressure gradient and is at risk of residual shunting. In this report, a transatrial approach is used, with direct suture of the VSR, patch exclusion of the right ventricle, and biological glue instillation to protect the patch from left ventricular pressures.
