Large-tip, dual-energy ablation catheter shows promise as treatment for persistent AF

A platform with a mapping system and a large-tip catheter with dual pulsed field and radiofrequency energies was noninferior to a conventional radiofrequency ablation system for treatment of persistent atrial fibrillation, data show. For the SPHERE Per-AF noninferiority trial, presented at Heart Rhythm 2024 and simultaneously published in Nature Medicine, the researchers randomly assigned 420
