目的 总结婴幼儿左室流出道梗阻（ＬＶＯＴＯ） 的外科治疗经验。方法 选自我院２１ 例ＬＶＯＴＯ，年龄１１ 个月～２．９ 岁，体重８ ．７～１３ ｋｇ，主动脉瓣上狭窄３ 例、瓣膜狭窄８ 例、瓣下狭窄６ 例、复合狭窄４ 例。结果 术后死亡２ 例，病死率９ ．５ ％ ，存活病例术后随访效果满意。结论 ＬＶＯＴＯ 系进展型疾病，易并发主动脉瓣返流、细菌性心内膜炎，应尽早手术治疗。手术预后与术前左心功能、二尖瓣瓣环直径、主动脉阻断时间有关。
Objective To summarize the surgical experience of infants with left ventricular outflow tract obstruction (LVOTO). Methods selected from our hospital 21 cases of LVOTO, age 11 months to 2.9 years old, weight 8. 7 to 13 kg, 3 cases of aortic stenosis, 8 cases of valvular stenosis, 6 cases of subvalvular stenosis and 4 cases of complex stenosis. Results Postoperative death in 2 cases, the mortality rate 9. 5%, Survival cases were followed up with satisfactory results. Conclusion LVOTO Department of progressive disease, complicated with aortic regurgitation, bacterial endocarditis, surgical treatment should be as soon as possible. The prognosis of surgery was related to preoperative left ventricular function, mitral valve annulus diameter and aorta blocking time.
