[Valvuloplasty for aortic insufficiency in a patient with bicuspid aortic valve].
A 20-year-old man with a bicuspid valve underwent aortic valvuloplasty for aortic regurgitation. Valvuloplasty was performed according to Cosgrove's method. Intraoperative transesophageal color Doppler echocardiography showed trivial aortic regurgitation after the repair. Peak pressure gradient across the repaired aortic valve was 9.3 mmHg at rest (cardiac output 4.2 l/min, stroke volume 49 ml) and 27.6 mmHg at dobutamine infusion (cardiac output 8.7 l/min, stroke volume 78 ml). The patient was in NYHA class I with no medication after surgery. Valvuloplasty for aortic regurgitation with a bicuspid valve is the surgical procedure of choice.
