The Lead Episode 113: A Discussion on the Effect of Pulsed-Field Ablation on Human Coronary Arteries: A Longitudinal Study With Intracoronary Imaging LIVE from Heart Rhythm 2025 in San Diego
Description
Please join host Michael S. Lloyd, MD, FHRS at HRS 2025 in San Diego as he discusses this article with Stephanie Wang, MD and Emily Zeitler, MD. The study investigated whether PFA-induced coronary spasms during ablation could cause lasting changes—such as mild lumen narrowing—at the ablation site over a three-month period.
Learning Objectives
  • To assess the long-term effects of pulsed-field ablation (PFA) on coronary arteries in patients treated for atrial flutter (specifically at the cavotricuspid isthmus [CTI] and mitral isthmus [MI]).
