Introduction
Ventricular septal rupture (VSR) is a rare and life-threatening complication following myocardial infarction, and ventricular septal dissection is even less common. The VSR can extend into the intraventricular wall, right ventricular free wall, left ventricular free wall, and ventricular septum as an intramyocardial dissection. A few reports describe how to repair a right and left ventricular free wall dissection with VSR (1-4). However, a repair technique for a ventricular septal dissection with VSR has rarely been described. We report here an extremely rare case of ventricular septum dissection and how we treated it.
