The Lead Episode 166: A Discussion of Relationship Between Time-to-First Atrial Tachyarrhythmia Recurrence and Atrial Fibrillation Burden: Implications for Trial Design-The Lead Episode 166 Bonus Video File

Video Transcription

Video Summary

The podcast discussed a 2025 Circulation: Arrhythmia and Electrophysiology study by Jason Andrade on atrial fibrillation recurrence after rhythm-control treatment. Using two large trials, the authors found that earlier recurrences after the blanking period were associated with much higher AF burden later, while late recurrences tended to have low burden. The guests debated whether six-month follow-up could replace one-year follow-up in trials: it would be more practical and cheaper, but could miss important recurrences. Clinically, they agreed timing and burden matter, and management should still be guided largely by symptoms and patient-specific risk.
