Transcatheter aortic valve replacement (TAVR) patients given pacemakers operating in mandatory DDD mode had more ventricular pacing, heart failure hospitalization, and mortality compared with AAI-DDD or VVI modes. AV conduction disturbances are often transient after TAVR. Minimizing ventricular pacing where possible avoids the risk of pacemaker-induced cardiomyopathy. Pacemaker specialists should be consulted for any TAVR patient with mild rhythm abnormalities given the high incidence of AV block. Careful stratification of patients with conduction disturbances during TAVR may help identify the patients who will require an early permanent pacemaker implantation strategy.
与AAI-DDD或VVI模式相比，接受以强制DDD模式运行的起搏器的经导管主动脉瓣置换术（TAVR）患者有更多的心室起搏、心力衰竭住院和死亡情况。TAVR后房室传导障碍通常是短暂的。尽可能减少心室起搏可避免起搏器诱发的心肌病风险。鉴于房室传导阻滞的高发生率，对于任何有轻度节律异常的TAVR患者，都应咨询起搏器专家。在TAVR期间对传导障碍患者进行仔细分层，可能有助于识别需要早期永久起搏器植入策略的患者。
