Circ:Cardiovasc Inte:TAVI后的冠脉通路和经皮冠脉介入治疗

2020-06-27 xiangting MedSci原创

大型SOURCE 3欧洲登记中,3.5%的患者在球囊扩张瓣膜TAVI后的3年随访中需要CA,并且所有患者均成功实现了CA。经皮冠脉介入治疗的临床成功率为97.9%。

冠状动脉疾病和主动脉瓣狭窄经常并存。对于最终需要治疗冠脉疾病的年轻低风险患者,经导管主动脉瓣植入术(TAVI)已成为一种有效的治疗选择。因此,TAVI后的冠脉通路(CA)和经皮冠脉介入治疗预期将会增多。这项研究目的是回顾性评估SOURCE 3欧洲登记(SAPIEN 3主动脉瓣膜欧洲结局)中使用球囊扩张SAPIEN 3经导管心脏瓣膜,并在TAVI后接受伴或不伴经皮冠脉介入治疗CA的患者 。

比较了TAVI后长达3年内有或没有CA患者的基线特征和临床结局。使用单因素模型进行Kaplan-Meier估算确定CA对心脏死亡率的影响。

1936名TAVI患者中(平均年龄81.6岁,男性52%),68名(3.5%)在TAVI后3年内(平均441±332天)伴有CA。基线时,logistic EuroSCORE相似(CA和非CA组分别为20.2%vs 18.3%,P=0.2)。CA组冠脉疾病(76.5%vs 50.6%,P<0.001)、心肌梗死(20.6%vs 11.5%,P=0.03)和既往冠脉搭桥术的发生率较高(22.1%vs 11.0%,P=0.01)。在100%的患者中成功实现了CA。经皮冠脉介入治疗的临床成功率为97.9%。有CA患者的血管死亡率在数值上高于无CA患者。

大型SOURCE 3欧洲登记中,3.5%的患者在球囊扩张瓣膜TAVI后的3年随访中需要CA,并且所有患者均成功实现了CA。经皮冠脉介入治疗的临床成功率为97.9%。
