Results of Surgical Treatment of Patients with Diffuse Subvalvular Aortic Stenosis
Sixteen patients with diffuse hypertrophic subaortic stenosis have been treated surgically. Thirteen of 14 patients undergoing excision of hypertrophied muscle from the left ventricular outflow tract via left ventriculotomy or aortotomy have survived. Operation has provided excellent symptomatic relief, associated with eradication or significant reduction of the systolic pressure gradient between the left ventricle and the aorta while the patient is at rest. Operation is recommended for those patients with this disease who are experiencing significant and limiting symptoms related to obstruction of the left ventricular outflow tract.
