Step‐by‐Step: How to Perform Pulsed Field Ablation of Atrial Fibrillation Guided Exclusively by Intracardiac Echocardiography Using a Pentaspline Catheter

David Santacruz‐Pacheco · Juan Carlos Díaz · Armando Pérez‐Silva · Vladimir Astudillo · y 6 más

ABSTRACT Pulsed‐field ablation (PFA) is an emerging technique for pulmonary vein isolation in atrial fibrillation. However, its implementation is commonly guided by fluoroscopy with or without 3D electroanatomic mapping, increasing either radiation exposure or procedural cost. We describe a practical, step‐by‐step work...

SOFA-2 represents meaningful progress toward a more inclusive and equitable global sepsis assessment framework
