Why the study?
Intracardiac echocardiography (ICE) is increasingly used as an alternative to transesophageal echocardiography for guiding left atrial appendage occlusion, but the lack of a standardized imaging protocol has slowed its clinical adoption.
How should intracardiac echocardiography be used to guide transcatheter left atrial appendage occlusion?
How should intracardiac echocardiography be used to guide transcatheter left atrial appendage occlusion?
This expert consensus document provides a standardized protocol to facilitate the adoption of intracardiac echocardiography for guiding left atrial appendage occlusion.
Standardizes ICE guidance for LAAO to improve consistency; extends prior imaging recommendations into a unified protocol for adoption.
Transcatheter left atrial appendage occlusion (LAAO) is an increasingly used alternative to oral anticoagulation in selected patients with atrial fibrillation. Intraprocedural imaging is a crucial for a successful intervention, with transesophageal echocardiography (TEE) as the current gold standard. Since some important limitations may affect TEE use, intracardiac echocardiography (ICE) is increasingly used as an alternative to TEE for guiding LAAO. The lack of a standardized imaging protocol has slowed the adoption of ICE into clinical practice. On the basis of current research and expert consensus, this paper provides a protocol for ICE support of left atrial appendage occlusion.

Berti et al. (2021) conducted a review in Atrial fibrillation. Intracardiac echocardiography (ICE) guidance vs. Transesophageal echocardiography (TEE) was evaluated. An expert consensus document provides a standardized imaging protocol for intracardiac echocardiography support during transcatheter left atrial appendage occlusion.
