Ventricular Septal Defect due to Septal Infarction after Repair of Tetralogy of Fallot

Abstract A case is reported of ventricular septal defect resulting from septal infarction following repair of a tetralogy of Fallot. The infarct probably resulted from division of a septal coronary artery during resection of the hypertrophied infundibulum. The superficial position of the septal artery on the right side of the septum in tetralogy makes it surprising that this complication has not been previously reported.
