Background: Intracardiac echocardiography (ICE) technology has been increasingly accepted as an integral part of atrial fibrillation (AF) ablation procedures. It is still unknown whether ICE can routinely replace transesophageal echocardiography (TEE) for routine thrombus screening in non‐selective AF patients. Objective: To assess whether ICE can routinely replace TEE in screening for left atrial (LA)/left atrial appendage (LAA) thrombus in general patients undergoing catheter ablation for AF. Methods: A total of 2003 consecutive patients undergoing AF ablation were included. 1155 patients (ICE group) received intra‐procedural ICE examination for LA/LAA thrombus screening, while 848 patients (TEE group) received pre‐procedure TEE examination. The incidence of thrombus, peri‐procedure complications, and hospital efficiency were assessed. Results: The LA and LAA were adequately visualized in all patients. Five patients in the ICE group and 15 patients in the TEE group were found to have LAA thrombus. The incidence of major periprocedural thrombo‐embolic events was comparable between two groups (0.2% vs. 0.1%, p =.76), none were due to undetected LA/LAA thrombus. Other major periprocedural complications occurred at similar rates in both groups, while post‐procedure fever was less common in the ICE group (12.7% vs. 17.4%, p <.001). Procedure times and hospital length of stay were both shorter in the ICE group (142 min [87–197 min] vs. 150 min [95–205 min], and 3[2–4] day vs. 4[3–5] day, respectively, both p <.001). Conclusions: ICE can replace TEE for atrial thrombus screening in AF patients undergoing ablation without increased complications. An "ICE replacing TEE" workflow can also reduce the incidence of postoperative fever and improve hospital efficiency. [ABSTRACT FROM AUTHOR]
