Key result
Surgery for muscular subaortic stenosis relieves obstruction but carries ~19% hospital mortality.
Why the study?
Surgical treatment techniques for muscular subaortic stenosis and their outcomes require evaluation to recommend effective approaches for obstructive cardiomyopathy.
Observational (n=26)

High mortality tempers early surgical adoption despite obstruction relief; leaves open optimal management of muscular subaortic stenosis.
The results of surgical treatment of 26 patients with muscular subaortic stenosis are presented. Left ventricular septectomy was performed in 16 patients, and septal myocardiectomy via a right ventriculotomy was employed in the last ten patients. There were five hospital deaths among these patients, yielding a mortality rate of 19%. Hemodynamic studies after operation in six patients showed relief of functional left ventricular outflow obstruction in all but one patient. This patient subsequently underwent successful right ventricular septectomy. Recently we have employed a right ventriculotomy for excision of septal myocardium during digital exploration of the left ventricular outflow tract. Freedom from serious complications and effectiveness in relieving the subaortic stenosis recommend this technique for patients with obstructive cardiomyopathy.
