The need for creation or enlargement of a ventricular septal defect (VSD) is a rare occurrence. It is most frequently required in patients with double-outlet right ventricle who develop restriction of a remote muscular VSD or obstruction of a perimembranous VSD secondary to atrioventricular (AV) valve attachments to the interventricular septum. Surgical and transcatheter options for VSD creation or enlargement are associated with several risks including heart block, AV valve injury, and perforation. We report the first description of a hybrid approach to VSD creation and enlargement in two patients.
