Key result
In a real-world cohort of patients receiving the Micra-AV leadless pacemaker, 65% achieved adequate atrial synchronous ventricular pacing (≥70%), which was associated with active device troubleshooting.

What are the characteristics and predictors of achieving adequate atrioventricular synchrony (AsVP ≥ 70%) in patients receiving Micra-AV leadless pacemakers?
In real-world practice, 65% of patients with Micra-AV leadless pacemakers achieved adequate AV synchrony, with success predicted by lower BMI, absence of heart failure, and active device troubleshooting.
Kowlgi et al. (2022) conducted a cohort in Patients undergoing Micra-AV implants (n=56). Micra-AV transcatheter pacing system vs. Patients with AsVP < 70% was evaluated on Achievement of atrial synchronous ventricular pacing (AsVP) ≥ 70%. In a real-world cohort of patients receiving the Micra-AV leadless pacemaker, 65% achieved adequate atrial synchronous ventricular pacing (≥70%), which was associated with active device troubleshooting.
