Lancet:微创经导管修复三尖瓣反流

2019-11-08 QQY MedSci原创

三尖瓣反流是一种发病率和死亡率较高的常见疾病,治疗方法有限。研究人员在欧洲和USA的21个地点开展了一项前瞻性、多中心的单臂研究,评估TriClip,一种微创经导管的三尖瓣修复术,用于减轻三尖瓣反流的有效性和安全性。该研究招募中度及以上、NYHA评分≥II级、采取过充分治疗的三尖瓣反流患者。排除肺动脉收缩压>60 mmHg、既往进行过三尖瓣手术或植入了心血管电子装置的患者。予以受试患者Tri

三尖瓣反流是一种发病率和死亡率较高的常见疾病,治疗方法有限。研究人员在欧洲和USA的21个地点开展了一项前瞻性、多中心的单臂研究,评估TriClip,一种微创经导管的三尖瓣修复术,用于减轻三尖瓣反流的有效性和安全性。

该研究招募中度及以上、NYHA评分≥II级、采取过充分治疗的三尖瓣反流患者。排除肺动脉收缩压>60 mmHg、既往进行过三尖瓣手术或植入了心血管电子装置的患者。予以受试患者TriClip三尖瓣修复系统治疗。主要疗效终点是术后30天时三尖瓣反流严重性至少减轻一个等级(共分5个等级:轻、中、重、剧重、特重)。主要安全性终点是6个月时的严重副作用事件发生率。

2017年8月1日-2018年11月29日,共招募了85位患者(平均77.8岁,56位女性),均进行了TriClip治疗。30天时,83位有可用的超声心动图数据和图像的患者中有71位(86%)的三尖瓣反流严重程度至少减轻了一个等级。单边低于97·5%置信值的为76%,远大于预定的35%的表现目标。一位患者在6个月随访前撤出试验(无严重副作用事件)被排除安全性分析。6个月时,3位(3/84,4%)患者发生过一次严重副作用事件,远低于预定的39%。5位(5/72)患者出现单瓣叶附着。无围手术期死亡、转为手术、器械栓塞、心肌梗死卒中发生。6个月时,4位患者死亡。

TriClip系统可安全有效的降低三尖瓣反流,至少可减轻一个等级,可明显改善6个月的临床预后。

Circulation:伴有心室收缩功能障碍的中重度三尖瓣反流的患者预后极其不良

三尖瓣中重度反流的患者,是否进行干预取决于右心室(RV)大小和功能。中重度继发性TR心室重构的机制基本尚未明确。现研究人员对中重度继发性TR患者的心室重构进行研究。本研究共纳入1292位中重度继发性TR患者(中位年龄71岁,男女各一半),采用经胸超声心动图判断其是RV重构状态。根据RV扩张(三尖瓣环≥40mm)和RV收缩功能障碍(三尖瓣环收缩偏移平面<17mm)将RV重构分为4个等级:1级,

JACC:经导管三尖瓣重建治疗中重度三尖瓣反流安全有效

严重的三尖瓣反流(TR)与高的死亡率相关,且治疗手段有限。本研究的目的旨在评估经导管三尖瓣重建系统在30例中重度TR患者中的6个月安全性和有效性。本研究纳入了TRI-REPAIR临床研究中的30例中重度、有临床症状的且不适外科手术治疗的TR患者,并对患者术前及术后6个月的临床、功能和超声心动图资料进行分析。患者的平均年龄为75岁,女性占73%,23%患者有缺血性心脏病,在基线水平,有83%的患者的
