A 55-year-old lady underwent repeat aortic valve replacement using a 16-mm Carbomedics prosthesis. She made an uneventful postoperative recoveryand now leads an unrestricted life. Doppler echocardiography reveals a21-mm Hg gradient across the valve at rest. This did not increase with aninfusion of 30 mcg/kg per min of dobutamine, which resulted in an increasein the cardiac output from 1.96 to 5.46 l/min.
