Remote ambulatory cardiac monitoring (rACM) could identify high-grade atrioventricular block (AVB) before and after transcatheter aortic valve replacement (TAVR). Retrospective analysis of patients undergoing TAVR, with 14-day rACM before and after TAVR, was performed. Of 62 patients undergoing TAVR, 41 patients had rACM before TAVR. Three patients had asymptomatic AVB leading to planned pacemaker (PM) implant. After TAVR, 23 patients had rACM, with 1 patient requiring a PM implant for asymptomatic AVB. Five patients underwent unplanned PM after TAVR. Using rACM, almost half of PM implants in TAVR recipients were identified electively. High-grade AVB requiring PM was identified in nearly 10% of patients before TAVR.
远程动态心脏监测（rACM）可在经导管主动脉瓣置换术（TAVR）前后识别高度房室传导阻滞（AVB）。对接受TAVR且在TAVR前后进行了14天rACM的患者进行了回顾性分析。在62例接受TAVR的患者中，41例在TAVR前进行了rACM。3例患者有无症状AVB，导致计划植入起搏器（PM）。TAVR后，23例患者进行了rACM，1例患者因无症状AVB需要植入PM。5例患者在TAVR后接受了非计划PM植入。使用rACM，TAVR接受者中近一半的PM植入是通过选择性识别的。在TAVR前，近10%的患者被识别出需要PM的高度AVB。
