手术修复治疗二尖瓣脱垂引起的二尖瓣关闭不全时,瓣叶切除和保留之间需要达到适合的平衡。Vincent Chan等进行了一项随机对照的临床试验,旨在对比瓣叶切除和瓣叶保留这两种技术对患者临床预后的影响,特别是对于功能性二尖瓣狭窄的患者。

来自7个心脏专科手术中心的104位拟进行二尖瓣切除或保留手术的退行性二尖瓣关闭不全的患者被随机分组。排除前叶或联合脱垂以及其他混杂因素导致的二尖瓣病变患者。主要终点是修复术后12个月时的运动高峰时的平均二尖瓣梯度。

研究流程

采用二尖瓣切除术的患者(n=54)的平均年龄为63.9±10.4岁,19%的为男性,胸外科医师学会风险评分为1.4±2.8%;接受二尖瓣保留治疗的患者(n=50)的平均年龄为66.3±10.8岁,男性占16%,胸外科医师学会风险评分为1.9±2.6%。

两组术后12个月运动高峰时的平均二尖瓣梯度

无围手术期死亡或转为二尖瓣置换病例。12个月时,二尖瓣切除组有3位患者、二尖瓣保留组有2位患者出现中度二尖瓣反流。二尖瓣切除和二尖瓣保留术后12个月时的运动峰值时的平均二尖瓣梯度分别为9.1±5.2 mm Hg和8.3±3.3 mm Hg(P=0.43)。两组的静息状态下的峰值(8.3±4.4 mm Hg vs 8.4±2.6 mm Hg; P=0.96)和平均静息峰值(3.2±1.9 mm Hg vs 3.1±1.1 mm Hg; P=0.67)均无明显差别。切除组和保留组的6分钟步行距离分别是451±147 m和481±95 m(P=0.27)。

总之,本次随机试验显示,通过二尖瓣切除或二尖瓣保留修复手术治疗退行性二尖瓣脱垂导致的二尖瓣关闭不全,患者术后12个月时运动高峰状态下的二尖瓣梯度相近。该研究结果不支持“二尖瓣叶切除策略(相对于保留策略)与功能性二尖瓣狭窄风险相关”的假设。
