JACC:携带起搏器或除颤器导线患者的TTVI结局

2020-03-03 xiangting MedSci原创

TTVI在选定的携带CIED导线患者中是可行的,短期手术成功率和短期临床结局与没有三尖瓣导线的患者相当。

经三尖瓣心脏植入式电子设备(CIED)导线对三尖瓣瓣膜功能的干扰可能会引起三尖瓣返流(TR),并在经导管三尖瓣介入治疗(TTVI)期间对治疗提出了某些挑战。存在CIED情况下的TTVI可行性和疗效尚不清楚。目前存在CIED导线情况下的TTVI可行性尚未得到广泛证明。

研究人群包括来自TriValve登记(经导管三尖瓣治疗)的470名严重症状性TR患者,这些患者于2015年至2018年在21个中心接受了TTVI治疗。评估了CIED与预后的相关性。

470名患者中有121名(25.7%)携带术前CIEDCIED导线最常见的位置是后中隔连合(44.0%)。与没有跨瓣导线的患者相比(无CIED组),有三尖瓣导线的患者(CIED组)症状更多(纽约心脏病协会功能分级IIIIV级分别为95.9vs.92.3%;p=0.02),既往发生过右心衰竭的频率更高(87.8vs.69.0%;p=0.002)。非CIED患者的TR更为严重(有效的反流口面积0.7±0.6cm2 vs.0.6±0.3cm2p=0.02),但右心室功能明显更好(三尖瓣环平面收缩期偏移= 16.7±5.0mm vs. 15.9±4.0mmp=0.04)。总体而言,有373名患者(79%)接受了MitraClip治疗(雅培血管,圣克拉拉,加州)(CIED106[87.0])。其中,154名患者(33%)同时进行了经导管二尖瓣修复(CIED组为55[46.0],全部使用MitraClip)。无CIED患者的手术成功率为80.0%,CIED患者的手术成功率为78.6%(p=0.74),院内死亡率分别为2.9%和3.7%(p=0.70)。30天时,在70.8%的无CIED患者和73.7%的CIED患者中观察到了残余TR≤2+p=0.6)。两组均观察到症状改善(30天时,NYHA功能分级 III级:66.0vs. 65.0%; p=0.30)。12个月时无CIED患者生存率为80.7±3.0%CIED患者为73.6 ± 5.0%

TTVI在选定的携带CIED导线患者中是可行的,短期手术成功率和短期临床结局与没有三尖瓣导线的患者相当。
