Why the study?

To characterize individual-case medical device reports submitted to the FDA MAUDE database for commercially available pulsed-field ablation systems during early postmarket use.

Population

10,976 individual-case medical device reports from the FDA MAUDE database

Design

Post-market surveillance database analysis

Key result

Among 10,976 FDA MAUDE reports for pulsed-field ablation, 66.7% involved device malfunction without patient injury and 32.4% involved patient injury.

Overview

MAUDE reports associate pulsed-field ablation with malfunctions and injuries; hypothesis-generating for prospective safety registries.

Key Points

  • To characterize individual-case medical device adverse event reports submitted to the FDA MAUDE database for commercially available pulsed-field ablation systems during early post-market clinical adoption.
  • Analyzed medical device reports submitted to the FDA Manufacturer and User Facility Device Experience (MAUDE) database between February 1, 2024, and April 30, 2026.
  • Merged event, device, patient, problem code, and narrative files by report key, excluding literature-derived, clinical trial, false-positive, indeterminate, and exact duplicate reports (cohort N=10,976).
  • Device malfunction without patient injury accounted for 7,323 reports (66.7%), patient injury was documented in 3,554 reports (32.4%), and 197 reports involved patient death.
  • The most common clinical adverse event categories included tamponade, perforation, or pericardial effusion (n=1,014), arrhythmia or hemodynamic events (n=444), stroke, TIA, or neurovascular events (n=383), and coronary spasm or ischemia (n=324).

Early post-market surveillance of pulsed-field ablation systems in the FDA MAUDE database identifies device malfunctions and specific clinical adverse events, highlighting priorities for future prospective registries.

Limitations

  • Cannot estimate incidence from report-level surveillance analysis
  • Cannot estimate incidence, only characterizes report and event categories

Cite This Study

Gu et al. (2026) conducted an observational in Atrial fibrillation (n=10,976). Pulsed-field ablation was evaluated on Reporting phenotypes and clinical event categories. Among 10,976 FDA MAUDE reports for pulsed-field ablation, 66.7% involved device malfunction without patient injury and 32.4% involved patient injury.
