Phased‐Array Intracardiac Echocardiography to Guide Radiofrequency Ablation in the Left Atrium and at the Pulmonary Vein Ostium

Echocardiography and Pulmonary Vein Ablation. Introduction: We sought to evaluate the utility of a phased‐array intracardiac echocardiography (ICE) device to identify left atrial (LA) and pulmonary vein (PV) anatomy; accurately guide radiofrequency ablation (RFA) to the right or left PV ostium and LA appendage (LAA); and evaluate PV blood flow before and after RFA using Doppler parameters.
