主动脉瓣二瓣畸形所致主动脉瓣狭窄的外科治疗

目的 总结主动脉瓣二瓣畸形所致的单纯主动脉瓣狭窄外科手术治疗经验.方法 1993年5月至2007年12月,共收治主动脉瓣二瓣畸形所致的单纯主动脉瓣狭窄病人103例,其中男66例,女37例.年龄15～75岁,平均(52.9±13.2)岁.心功能Ⅱ级58级,Ⅲ级33例,Ⅳ级12例.所有病人均接受主动脉瓣置换术,同期行左室流出道疏通2例、房颤射频消融2例、升主动脉替换7例,冠状动脉旁路移植11例.结果 手术死亡1例(死亡病0.93%),Ⅲ度房室传导阻滞1例,余者均治愈出院.随访6个月～14年,平均(86.3±26.8)个月.失访14例,随访率84.2%.3例出现脑出血或栓塞并发症,1例猝死,1例非心脏原因死亡.最后随访心功能Ⅰ级67例,Ⅱ级17例,Ⅲ级2例.结论 主动脉瓣置换治疗主动脉瓣二瓣畸形所致的单纯主动脉瓣狭窄有较好的疗效,合并升主动脉扩张应积极处理.

Surgical treatment management offor isolated bicuspid aortic stenosis in patients with bicuspid aortic valve

Objective Bicuspid aortic valve is thea most common reason cause forof aortic valve replacment in patients with isolated aortic stenosis. Severe valve calcification and ascending aorta dilation are often related to the bicuspid aortic valve. Proper surgical intervention of these patients are very importing, and it may improve affed.the long-term results.Our experience in surgical management of isolated aortic stenosis in atients with bicuspid aortic valve is reported. Methods From May. 1993 to Dec. 2007, 103 consecutive patients' data with of isolated aortic stenosis and with bicuspid aortic valve underwent surgery icalwere collected and analyzed treatm.ent. There were 66 males and 37 females, and aAge ranged from 15 years to75 years [mean(52.9±3.2 )years]. 58 Fifty eight patients were in heart function (NYHA) class Ⅱ, 33 cases were in class Ⅲ, and 12 cases in class Ⅳ. All patients received aortic valve replacement. Severe aortci aortic valve calcification existed were found in 55 patients,and ascending aorta dilation (aorta diameter largerthan > 4.5 cm) occurred in 7 cases. Concomitant procedures were as followingfollows: left ventricular out-flow obstruct correction in 2 cases, radio-frequency ablation for atrial fibrillation in 2 cases, ascending area replacement in 7 cases, and coronary artery bypass graft in 11 cases. Results Operative death occurred in 1 patient (mortality0.93%). Complete atrioventricular block occurred in 1 patient. Others The rest were all recovered and discharged. The follow-up ranged duration were from 6 months to 14 years [ (86.3 ± 6.8) months].14 casesFourteen patients lost in the follow-up. Three cases had Bbrain complications, occurred in 3 cases. Sudden death and no-cardiac death occurred in 1 patient, respectively. Heart function improved significantly after operation. 67 patients were in function class 1, 17patients were in Ⅱ, and 2 in class Ⅲ at the latest follow-up. Conclusion Aortic valvereplacement is an effective method for patients with bicuspid aortic stenosis trod bicuspid aortic valve. If patients associate withascending aorta dilation is associated, more aggressive method corresponding surgery should be considered.
