ABSTRACT

Discrete subaortic stenosis or subvalvular aortic stenosis (SAS) or obstructive subaortic membrane (SAM) tendsto be a progressive, severe defect that occurs most often in children. The symptoms and electrocardiographicfindings of discrete subaortic stenosis are similar to those of aortic valve stenosis. The usual criteria for diagnosis,localization of the gradient below the aortic valve at cardiac catheterization or angiographic demonstration ofdiscrete subaortic stenosis, are not always evident. Echocardiography may aid in determining the diagnosis bydemonstrating the membrane in the left ventricular outflow tract (LVOT) and moreover, recognising the earlysystolic closure of the aortic valve leaflets. An acceptable low surgical mortality rate can be achieved; however,some patients require aortic valve replacement or multiple operations for adequate repair of their defect. Patientswith a thin membrane generally have a more favorable result than those with fibro-muscular collar or secondarymuscular hypertrophy. Aortic regurgitation is not always predictable and may recur or progress postoperatively.We are presenting a case report of a 52 year old obese female afflicted with discrete SAM with associatedbicuspid aortic valve (BAV) and LVOT obstruction alongwith atypical chest pain.
