Key result
14-day remote monitoring identifies high-grade AVB requiring pacemaker implantation in ~10% of pre-TAVR patients.
Why the study?
Remote ambulatory cardiac monitoring could identify high-grade atrioventricular block before and after transcatheter aortic valve replacement, but its utility was not well defined.
Does 14-day remote ambulatory cardiac monitoring identify high-grade atrioventricular block requiring pacemaker implant in patients undergoing TAVR?
Observational (n=62)
Does 14-day remote ambulatory cardiac monitoring identify high-grade atrioventricular block requiring pacemaker implant in patients undergoing TAVR?
14-day remote ambulatory cardiac monitoring before and after TAVR can proactively identify patients with asymptomatic high-grade AVB requiring pacemaker implantation.
May support pre-TAVR monitoring in select patients; leaves open whether routine use improves outcomes without randomized trials.
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.

Winter et al. (2020) conducted an observational in Transcatheter aortic valve replacement (TAVR) (n=62). 14-day remote ambulatory cardiac monitoring (rACM) was evaluated on Identification of high-grade atrioventricular block (AVB) requiring pacemaker implant. 14-day remote ambulatory cardiac monitoring identified high-grade atrioventricular block requiring elective pacemaker implantation in nearly 10% of patients before TAVR.
