A Novel Surgical Technique to Address Post-Septal Myectomy Ventricular Septal Defect.

Iatrogenic ventricular septal defect is a rare complication in patients undergoing septal myectomy for hypertrophic obstructive cardiomyopathy, and it necessitates closure in the postoperative period. We describe a novel surgical technique for closure of the ventricular septal defect using a biventricular approach with a custom-made polytetrafluoroethylene device. Our method is easily reproducible.
