Leadless versus transvenous single-chamber ventricular pacemakers: 3 year follow-up of the Micra CED study

George H. Crossley et al.

Summary: The Micra CED Study compared the outcomes of Micra pacemakers and transvenous VVI pacemakers using administrative claims data. It found that after 3 years of follow-up, patients with Micra had lower rates of complications, reinterventions, heart failure hospitalizations, and infections compared to patients with transvenous VVI.

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.

Experience with malfunctioning leadless pacemakers: Troubleshooting and management during medium-term follow-up

Erik F. J. Oosterwerff et al.

Summary: This study reported the experience of managing malfunctioning Nanostim LPs, including premature battery depletion, in 51 consecutive patients who underwent implantation between 2014 and 2016. The incidence of early-life battery failure was higher than previously reported, with successful extraction and replacement of Nanostim LP in a subset of patients. Three-monthly follow-up was effective in preventing in-between Nanostim LP-related hospitalizations.

Tissues attached to retrieved leadless pacemakers: Histopathological evaluation of tissue composition in relation to implantation time and complications

Karel T. N. Breeman et al.

Summary: The study found that tissue adhesion is common during leadless pacemaker retrieval, mainly consisting of fibrosis and thrombus which may affect the safety of retrieval. Leadless pacemakers may adhere to the heart's valves or subvalvular apparatus, suggesting risk stratification for excessive fibrotic encapsulation and adhesions should be considered in end-of-life strategy optimization.

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.
