Tricuspidization and reimplantation procedure for unicuspid aortic valve with annuloaortic ectasia.
Unicuspid aortic valve is a rare anomaly. We report 2 cases of successfully treated unicuspid valves with aortic dilatations by using a tricuspidization and reimplantation procedure. Two men, 35 and 39 years old, with severe aortic regurgitation and stenosis received this procedure. The sclerotic portion of a unicuspid valve, including 2 rudimentary commissures, was resected and reconstructed with autologous pericardium to create a tricuspid valve. An aortic root was replaced with a prosthetic graft. Postoperative echocardiogram showed trivial aortic regurgitation and minimal pressure gradient. Follow-up was 32 and 34 months, respectively. These valves remained stable in these periods. Tricuspidization and reimplantation is a promising procedure.
