Delayed Gerbode Defect After Transcatheter Aortic Valve Explantation: Right Atrial Repair With Tricuspid Leaflet Detachment

Year: 2026

Type: article

Abstract: Left ventricular–right atrial shunt (Gerbode defect) is a rare but serious complication after aortic valve surgery and may occur after transcatheter aortic valve explantation. We report an 81-year-old man who developed a delayed-onset Gerbode defect after surgical TAVR explantation. The shunt progressed to refractory heart failure and was unsuitable for transcatheter closure because of right ventricular involvement. Surgical repair was performed via a right atrial approach. Temporary partial detachment of the septal tricuspid leaflet provided improved exposure, allowing secure double-patch closure entirely from the right atrial side while preserving tricuspid valve function.
