Perforation of the interventricular septum complicating acute myocardial infarction is uncommon. The condition was first described anatomically by Latham in 1845 and the first antemortem diagnosis was made by Brunn in 1923. In both cases, bedside catheterization utilizing a flow directed catheter detected a step up of O2 saturation at the ventricular level, compatible with ventricular septal defect, and two dimensional echocardiogram allowed direct visualization and localization of the postmyocardial infarction VSD. Finally cineventriculogram confirmed them.
