摘要(Abstract)：
目的探讨主动脉瓣重度狭窄患者接受经导管主动脉瓣置换术(TAVR)治疗的有效性和安全性。方法回顾性选取2017年9月至2019年12月接受TAVR的主动脉瓣重度狭窄患者36例。收集患者的人口学、实验室检查、影像辅助检查等全部临床资料,对手术过程、成功率、并发症以及手术前后超声心动图结果等进行分析。结果患者平均年龄(72.42±6.14)岁,瓣膜置入成功率100%。与术前相比,术后第1天的脑钠肽、主动脉瓣最大跨瓣压差、主动脉瓣跨瓣流速差异均有统计学意义(均P<0.01),术后6个月随访左心室射血分数、左心室舒张末期内径及左心室收缩末期内径都有显著改善(均P<0.01)。并发症方面,住院期间1例(2.8%)患者因三度房室传导阻滞行永久性起搏器植入;术后1周有2例(5.6%)患者存在轻度瓣周漏(<2mm),术后6个月随访时只有1例(2.8%)患者存在轻度瓣周漏;术后6个月随访时1例(2.8%)患者缺血性卒中。结论主动脉瓣重度狭窄患者行TAVR治疗有较好的安全性和有效性,可有效改善左心室重塑。
