Over a 12 months period, we treated 2 cases with discrete subaortic stenosis caused by membranous band. In one patient, who was 19 years old woman, the echocardiograms showed the discrete membrane and idiopathic hypertrophic subaortic stenosis [IHSS . She underwent transaortic myotomy and mymectomy simultaneously band resection. Other case of 11 year old boy with discrete subaortic stenosis only underwent membrane resection. Both patients had an uneventful hospital course, but 19 year old woman showed remained pressure gradient in follow up echocardiograms.
