TCT 2014:主动脉瓣狭窄患者TAVR获益明显(PARTNER I 试验)

2014-09-23 傅向华 白世茹 医学论坛网

TCT2014会议上公布了最新的PARTNER I研究5年的随访结果,数据显示,对于主动脉瓣严重狭窄的高危患者,若不适宜行外科手术,经导管主动脉瓣置换术(TAVR) 比常规治疗更能使其长期获益。 来自克利夫兰诊所的Samir Kapadia医学博士对358例不适宜行外科手术的主动脉瓣狭窄患者进行了临床研究,将其随机分为使用Saplen瓣膜(Edwards Lifesciences)的TA

TCT2014会议上公布了最新的PARTNER I研究5年的随访结果,数据显示,对于主动脉瓣严重狭窄的高危患者,若不适宜行外科手术,经导管主动脉瓣置换术(TAVR) 比常规治疗更能使其长期获益。

来自克利夫兰诊所的Samir Kapadia医学博士对358例不适宜行外科手术的主动脉瓣狭窄患者进行了临床研究,将其随机分为使用Saplen瓣膜(Edwards Lifesciences)的TAVR组(n=179)和常规药物治疗组(n=179)。

5年后,TAVR组患者的死亡率下降了21.8%。接受常规药物治疗的6例生存者中,5例患者于5年后都接受了某种方式的瓣膜置换,包括在美国之外接受的TAVR,外科主动脉瓣置换术和心尖-主动脉导管,另外1例接受了三次球囊主动脉瓣膜成形术。

此外,与常规治疗相比,TAVR患者的中位生存时间接近2.5年(29.7 vs. 11.1 months;P<0.001)。TAVR组患者的心血管事件死亡率更低(57.3% vs. 85.9%;P<0.001)。重要分析结果显示,TAVR组和常规治疗组3年至5年的全因死亡率分别是38.9%和66.7%(HR 0.47,95% CI 0.24-0.94)。

NEJM:经导管主动脉瓣置换术治疗无法手术的重度主动脉瓣狭窄患者

  背景  对于有重度主动脉瓣狭窄、并且不适宜手术治疗的患者,经导管主动脉瓣置换术(TAVR)是推荐的治疗。这类患者在1 年后的转归尚不清楚。   方法  我们将患者随机分为接受经股动脉TAVR或接受标准治疗(通常包括球囊主动脉瓣膜成形术)。我们对2年转归的数据进行分析。   结果  在21家医疗中心,共358例患者接受随机分组。2 年时,TAVR 组的死亡率为4

经导管主动脉瓣置入术:现状、进展和问题分析-附PARTNER研究解读

随着人类寿命的延长和人口的老年化,主动脉瓣疾病的发病率越来越高。在西方发达国家,钙化性主动脉瓣狭窄(calcific aortic stenosis ,CAS)发生率仅次于高血压和冠心病,已成为老年人瓣膜置换的首要病因。[1] 长期以来,外科主动脉瓣置换术(SAVR)一直是症状性主动脉瓣狭窄(AS)的主要治疗方式。但是,由于传统的外科手术创伤大、需要体外循环、手术风险高,30%-50%患者因高龄、
