Key result
ICE guides EP procedures with real-time imaging but requires added training and venous access.
Why the study?
Intracardiac echocardiography (ICE) is increasingly used in electrophysiology laboratories but requires additional training and understanding of catheter manipulation and image interpretation.
Intracardiac echocardiography is a valuable adjunctive imaging tool in the electrophysiology laboratory that facilitates real-time procedural planning and assessment when operators are adequately trained.
May enhance real-time guidance in electrophysiology procedures; leaves open optimal integration protocols versus existing imaging.
Intracardiac echocardiography (ICE) is a catheter-based ultrasound probe that is used in the cardiac electrophysiology laboratory for real-time assessment of cardiac structures during electrophysiological studies. ICE requires additional vascular access, but provides real-time intracardiac analysis of cardiac structures. The imaging sector of ICE creates a fan from the side of the catheter tip that is perpendicular along the long axis of the ICE catheter, different from standard echocardiographic images. The near-field image shows structures proximal along the long axis of the catheter, whereas the far-field image shows structures distal along the long axis. The home view for ICE imaging has the catheter within the right atrium facing the tricuspid valve in the neutral position, with additional views obtained with clockwise rotation of the catheter. Careful attention is required when advancing the catheter in the body and interpreting the ICE images.

Haloot et al. (2026) conducted a review in Electrophysiology procedures requiring intracardiac echocardiography. Intracardiac echocardiography (ICE) was evaluated. Intracardiac echocardiography provides real-time, high-resolution imaging of cardiac structures to guide electrophysiology studies, though it requires specialized training and additional venous access.
