目的:评估主动脉瓣狭窄(AS)患者经导管主动脉瓣置换(TAVR)术前及术后室性心律失常(VAs)发生率。方法:连续收集自2018年1月1日-2019年12月31日在武汉亚洲心脏病医院接受TAVR治疗的症状性重度AS患者81例,排除TAVR术前存在永久起搏器植入...目的:评估主动脉瓣狭窄(AS)患者经导管主动脉瓣置换(TAVR)术前及术后室性心律失常(VAs)发生率。方法:连续收集自2018年1月1日-2019年12月31日在武汉亚洲心脏病医院接受TAVR治疗的症状性重度AS患者81例,排除TAVR术前存在永久起搏器植入病史、术后因并发症植入永久起搏器、术后30 d内死亡、术前无24 h Holter检查结果及失访的患者共14例,最终67例患者纳入分析。TAVR术前及术后1个月行24 h Holter观察VAs的发生情况。VAs分类依据改良的Lown分级系统。结果:TAVR术前VAs Lown分级为1~2级40例(59.7%),3~4级23例(34.3%)。TAVR术后1个月,VAs 1~2级人群占比升高,但差异无统计学意义(P>0.05)。3~4级人群比例显著降低(P<0.05)。其中,室性心动过速(VT)的发生率从11.9%下降至7.5%,但差异无统计学意义(P>0.05)。结论:VAs常见于AS人群中,TAVR术后1个月严重VAs(改良Lown分级3~4级)的患者比例显著降低,可能与瓣膜置换术后左心室功能改善有关。展开更多
