December 20, 2024- Northwell Lenox Hill Hospital is one of the first in the nation to successfully treat persistent atrial fibrillation (AFib) using a first-of-its-kind FDA-approved mapping and ablation system. The Affera Mapping and Ablation System’s innovative three-in-one catheter combines three advanced functions in one. It integrates high-density mapping technology to precisely identify the source of the irregular heart rhythm, while providing two ablation methods to target and disable the arrhythmia-causing cells: pulsed field ablation, delivering controlled bursts of electricity, and traditional radiofrequency ablation, applying targeted heat.
