          Abstract

          Seventy-two patients aged 2–65 years (mean 20.2) with fixed subaortic stenosis (FSS) are reported. All patients underwent echocardiography and angiography prior to surgical intervention. Sixty-four (89%) had discrete subaortic stenosis (DSS) and 8 (11%) tunnel type stenosis (TSS). Patients with DSS aged 2–65 years (mean 29) while patients with TSS aged 10–34 years (mean 19) and had a distinct female preponderance (7:1). Twenty-five patients (39%) with DSS had other congenital abnormalities of which aortic stenosis associated with bicuspid aortic valve was slightly more common than ventricular septal defect (7:6). Five patients with TSS had a small aortic annulus and hypoplastic aorta. Our data and those in the literature indicate that TSS although related to DSS has certain features that may set it apart as a distinct entity. In addition DSS appears to be associated with aortic stenosis and bicuspid aortic valve as frequently as with ventricular septal defect.

          Discrete membranous subaortic stenosis: improved results after resection and myectomy.

          Despite an adequate resection, a significant recurrence rate is encountered in patients undergoing operation for discrete membranous subaortic stenosis. The fibrous membrane and hypertrophied myocardium commonly are removed, but because of the involved risks, the resection may be inadequate and contribute to the recurrence rate.
