Over the past 5 years, 45 patients (11 adults and 33 children) have undergone operations for discrete and fixed subaortic stenosis. The resection of the subvalvular membrane or the fibromuscular collar was the procedure of choice. 28 patients underwent myectomy and/or myotomy. None patients died during operations. No significant symptoms and gradients remained after operation. We conclude that in the surgical management of fixed discrete subaortic stenosis myectomy and myotomy in addition to membranectomy produces better relief of the left ventricular outflow obstruction than do membranectomy alone.
