title: Noninvasive evaluation of membranous subaortic stenosis: complimentary roles of echocardiography and computed tomographic angiography.
abstract: A 29-year-old Ethiopian woman that was referred to the Wisconsin Heart Hospital for treatment of subaortic stenosis, diagnosed 4 years earlier, in Ethiopia, using transthoracic echocardiography. Preoperative evaluation included transesophageal echocardiography, which showed severe membranous subaortic stenosis with a mean outflow gradient of 70 mmHg. Cardiac computed tomographic angiography also demonstrated a subaortic membrane, and additionally showed normal epicardial coronary arteries. The patient underwent uneventful surgical resection of the subaortic membrane without undergoing cardiac catheterization.
