Intracardiac vs Transesophageal Echocardiography in Atrial Fibrillation Ablation: A Randomized Clinical Trial.

ABSTRACT:

Importance

Transesophageal echocardiography (TEE) is the standard imaging modality for thrombus screening prior to atrial fibrillation (AF) ablation but carries procedural risks. Intracardiac echocardiography (ICE) is an alternative that may offer comparable safety with procedural advantages.

Objective

To determine whether ICE is noninferior to TEE in preventing periprocedural thromboembolic events in AF ablation.

Design, setting, and participants

This multicenter randomized clinical trial was conducted at 10 hospitals in China from August 2022 to July 2023, with a 30-day follow-up, enrolling adults with AF scheduled for catheter ablation who met predefined eligibility criteria. Data analysis was performed from August 2023 to December 2023.
