What is the rate of long-term pacemaker dependency in patients requiring permanent pacemaker implantation following TAVR with the Lotus valve?
The majority of patients who require a permanent pacemaker after TAVR with the Lotus valve recover conduction over time, with only 38% remaining pacing dependent at one year.
OBJECTIVES: valve system (Boston Scientific), and the impact of PPM implantation on long-term morbidity and mortality. BACKGROUND: Conduction abnormalities are among the most common complications following TAVR. Limited studies have assessed pacing dependency following TAVR. METHODS: Consecutive patients (n = 166) with severe aortic stenosis who underwent TAVR with the Lotus valve system were prospectively recruited from a single-center. PPMs were implanted according to standard clinical criteria. Patients were followed in-hospital and at 1, 3, 6, and 12 months to determine pacemaker dependency and clinical outcomes. RESULTS: Fourteen patients with a pre-existing PPM (8%) were excluded with the remaining 152 patients aged 83.6 ± 5.6 years and 46% male. PPMs were implanted 3.8 ± 4 days post-TAVR in 38/152 patients (25%). Indication for PPM was complete heart block in 29 (76%) of patients. At 30-day and one-year follow up, 57% and 38% of patients were pacemaker dependent, respectively. The mean ventricular pacing percentage decreased in the first three months after PPM implantation and remained relatively stable after that. CONCLUSION: Only 38% of Lotus recipients who require a PPM following TAVR with the Lotus valve remain pacing dependent at one year.
Alasti et al. (Thu,) conducted a cohort in Severe aortic stenosis (n=152). Permanent pacemaker (PPM) implantation following TAVR with the Lotus valve was evaluated on Pacemaker dependency at one year. Among patients requiring a permanent pacemaker following TAVR with the Lotus valve, 38% remained pacemaker dependent at one year.
