JACC:三尖瓣二尖瓣联合修复与单独二尖瓣修复治疗严重MR合并TR的比较

2020-03-19 MedSci原创 MedSci原创

这项研究目的是在TriValve(经导管三尖瓣治疗)和TRAMI登记(经导管二尖瓣介入治疗)中回顾性比较二尖瓣返流(MR)合并三尖瓣返流患者(TR)的特征、手术过程和结局。

这项研究目的是在TriValve(经导管三尖瓣治疗)和TRAMI登记(经导管二尖瓣介入治疗)中回顾性比较二尖瓣返流(MR)合并三尖瓣返流患者(TR)的特征、手术过程和结局。

已经证明经导管二尖瓣缘对缘瓣膜修复(TMVR)可以成功治疗严重MR。最近,缘对缘修复也被作为心脏手术高危严重TR患者的可能治疗方法。在严重MR合并TR患者中,手术高危患者同时进行经导管二尖瓣和三尖瓣修复(TMTVR)的疗效尚不清楚。

回顾性比较了国际多中心TriValve登记和德国多中心TRAMI登记中所有严重MR合并TR患者的特征、手术数据和1年结局。TRAMI患者(n=106)接受了单独的TMVR,而TriValve患者(n=122)同时接受了TMTVR作为同情和/或标签外使用。

全部228例患者(平均年龄77±8岁,女性占44.3%)均在基线时表现出明显的呼吸困难(93.9%的患者纽约心脏病协会功能分级III或IV级),肺动脉高压和慢性肺病的比例无差异。TMVR组中左室射血分数<30%的患者比例更高(34.9%vs. 18.0%;p<0.001),而TMTVR组患者的肾小球滤过率较低。出院时,两组MR均相对降低。1年时,TMVR组的总全因死亡率为34.0%,TMTVR组为16.4%(p=0.035,Cox回归)。在多因素分析中,TMTVR与死亡率降低2倍相关(危险比:0.52;p=0.02)。1年时纽约心脏病协会功能分级≤II级的患者比例没有差异(69.4%vs. 67.0%;p=0.54)。

在MR合并TR患者中,同时进行TMTVR的1年生存率高于单独进行TMVR。需要进一步的随机试验来确认这些结果。
