摘要
目的总结25例主动脉瓣下狭窄的手术治疗经验。方法全组25例中男性13例,女性12例;年龄0.5～63岁,平均年龄23.25岁。均经超声心动图确诊为主动脉瓣下狭窄,先天性病变25例（隔膜型17例,肌纤维环型3例,局限型肌性隆起5例）,合并畸形15例。左室主动脉收缩压差（67.46±25.32）mm Hg。所有患者接受纤维隔膜或肌纤维环切除,并同期行矫正手术。结果术后主动脉瓣下狭窄均解除,全组患者无手术死亡及并发症。术后左室主动脉平均收缩压差2～50（12.50±10.57）mm Hg,较术前（67.46±25.32）mm Hg明显降低（P〈0.01）。结论外科手术是治疗该病的有效方法,手术要点是疏通瓣下狭窄要彻底。
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 membranous 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 mm Hg pre- operatively to 12. 50 ± 10. 57 mm Hg post-operatively（ P〈0. 01）. Conclusion Cardiac surgical procedure is the most effective way for the treatment of subaortic stenosis. Thoroughly dredging left ventricular outflow tract is the key point of the operation.
