Abstract：Objective To summarize the experience of surgical treatment of subaortic stenosis. Methods 25 patients with subaortic stenosis were treated surgically. The diagnosis was made by echocardiography. There were 13 males and 12 females. The mean age was 23.25 years ( range 0.5 to 63 years) . All the patients were diagnosed with congenital subaortic stenosis. 17 cases had membra?nous typestenosis,3 cases had fibromuscularring type stenosis, and 5 cases had discrete muscular type stenosis. Resection of stenosis membrane or ring was made in all the cases. In 15 patients combined with cardiovascular malformation, correction was offered at the same time. Results All patients were asymptomatic post-operatively. No operative death and complications were found in all patients. The mean systolic gradient of left ventricle to aorta decreased from 67.46±25.32 mmHg pre-operatively to 12.50±10.57 mmHg post-op?eratively( P<0.01) . Conclusion Cardiac surgical procedure is the most effective way for the treatment of subaortic stenosis. Thor?oughly dredging left ventricular outflow tract is the key point of the operation.
