We report a case of an 18-year-old female who presented with severe aortic stenosis and insufficiency, eight years following resection of a subaortic membrane. On echocardiography, she was found to have a completely fused or nullicuspid valve, with three equal sinuses and three commissural fusions. Aortic valve repair included leaflet tricuspidization, three commissurotomies, trileaflet ring annuloplasty, and pericardial leaflet reconstruction. At one year follow-up, the patient is asymptomatic, with stable gradients.
