A 55-year-old lady underwent repeat aortic valve replacement using a 1
6-mm Carbomedics prosthesis. She made an uneventful postoperative reco
very and now leads an unrestricted life. Doppler echocardiography reve
als a 21-mm Hg gradient across the valve at rest. This did not increas
e with an infusion of 30 mcg/kg per min of dobutamine, which resulted
in an increase in the cardiac output from 1.96 to 5.46 1/min. (C) 1997
