The Lead Episode 154: A Discussion of Safety and Effectiveness of a Dual-Energy Focal Ablation Catheter to Treat Paroxysmal Atrial Fibrillation: 6- Month Results of the FlexPulse IDE Study-he Lead Episode 154 Bonus Video File

Video Summary

In this Heart Rhythm Society podcast episode, Dr. Sandeep Saha discusses the late-breaking FlexPulse IDE study with Drs. Babak Nazer and Rajesh Kabra. The trial evaluated the TactiFlex Duo, a dual-energy focal ablation catheter that can deliver both pulse field ablation (PFA) and radiofrequency energy, for paroxysmal atrial fibrillation. In this single-arm, 188-patient study, pulmonary vein isolation was highly successful, with 93.9% first-pass isolation and 87.1% freedom from atrial arrhythmia at six months. Safety was favorable, with a 1.7% primary safety event rate and no strokes, esophageal injury, phrenic nerve injury, or deaths. The experts highlighted the catheter’s versatility, focal precision, and potential usefulness for redo cases, atypical flutter, ventricular tachycardia, and training. Limitations included longer procedure times and uncertain long-term implications, but overall the study was viewed as a promising step forward in catheter-based ablation.
