Leadless vs. transvenous single-chamber ventricular pacing in the Micra CED study: 2-year follow-up

Mikhael F. El-Chami et al.

Summary: The Micra leadless VVI pacemaker showed lower rates of reinterventions and chronic complications compared to transvenous VVI pacing in a real-world study of US Medicare patients, with no difference in all-cause mortality at 2 years.

Leadless atrioventricular synchronous pacing in an outpatient setting: Early lessons learned on factors affecting atrioventricular synchrony

Felix Neugebauer et al.

Summary: This study investigated AV synchrony and the impact of programming adjustments on AV synchrony in outpatients with leadless VDD pacemakers. The study found that achieving successful VDD pacing during higher sinus rates is challenging and often requires multiple reprogramming to optimize AV sequential pacing.

Wireless Communication Between Paired Leadless Pacemakers for Dual-Chamber Synchrony

Daniel J. Cantillon et al.

Summary: This preclinical study demonstrates the chronic performance of implant-to-implant communication that achieves synchronous, dual-chamber pacing with 2 leadless pacemakers, achieving a success rate of 99.2%.

Contemporaneous Comparison of Outcomes Among Patients Implanted With a Leadless vs Transvenous Single-Chamber Ventricular Pacemaker

Jonathan P. Piccini et al.

Summary: This study compared patient characteristics and complications between patients implanted with leadless VVI and transvenous VVI pacemakers. Despite significant differences in patient characteristics, patients with leadless VVI pacemakers had higher rates of pericardial effusion and/or perforation but lower rates of other device-related complications and revisions at 6 months.
