Abstract

The evaluation of aortic stenosis is not always straightforward. When symptoms of severe aortic stenosis are present with supporting Doppler echocardiographic or cardiac catheter-ization data, replacement of the aortic valve is recommended. Occasionally, Doppler- and catheter-derived data are discordant; appropriate treatment in such cases becomes less c l e ar. We report a case in which a 66-year-old man’s symptoms and Doppler data suggested severe aortic stenosis. However, heart catheterization data suggested otherwise, and ultimately it led to the diagnosis of a highly vascular renal tumor. Shunting within the tumor resulted in high cardiac output, which, in combination with a small aortic root, masqueraded as severe aortic stenosis.
