ReVolt Against the Ordinary: The Latest in Pulsed Field Ablation-ReVolt Against the Ordinary: The Latest in Pulsed Field Ablation

Video Transcription

Video Summary

In a session led by Frank Marchlinsky at the University of Pennsylvania, leading experts discussed advancements in pulse-field ablation (PFA) for treating atrial fibrillation. The discussion emphasized the Volt PFA system with an Abbott Balloon in-basket catheter, as presented by Dr. Helmut Puerl-Feldner. He highlighted its high success and safety in European trials, achieving up to 88.2% freedom from atrial fibrillation after six months post-procedure. Key features include eight splines acting as electrodes, a powerful energy delivery method, and two magnetic sensors for precision and safety during the procedure.<br /><br />Dr. Monica Lau discussed the TactiFlex PFA system, which combines both PFA and RF modalities, offering implementation flexibility during procedures. It can be utilized for complex cases, addressing various arrhythmias, and ensuring greater precision in lesion creation. Its effectiveness is demonstrated through precise mapping and minimal procedure times.<br /><br />Dr. Atul Verma emphasized the technological advancements needed in PFA, like measuring non-binary contact force and reducing adverse effects, including hemolysis and musculoskeletal stimulation. The session also addressed choices between single-shot and point-by-point techniques based on patient specifics and complexity.<br /><br />The dialogue underscored the need for tailored approaches based on patient diagnosis and technological capabilities to enhance outcome precision and safety—even hinting at an exciting future where technologies like the HD grid for VTs could dramatically improve treatment efficacy.
