Intracardiac echocardiography is a valuable imaging modality that enhances the safety, efficacy, and procedural workflow of electrophysiological interventions for atrial fibrillation and supraventricular tachycardias.
Researchers have investigated ways to develop optimal imaging techniques to increase the safety and effectiveness of electrophysiological (EP) procedures. Intracardiac echocardiography (ICE) is an advanced imaging tool that can directly visualize cardiac anatomical structures in high resolution, assess tissue heterogeneity and arrhythmogenic substrates, locate intracardiac catheters, monitor catheter-tissue contact and ablation injury in real-time, excluding intracardiac thrombi, and quickly detect procedural complications. Additionally, real-time imaging via ICE can be integrated with a three-dimensional (3D) electroanatomical mapping (EAM) system to reconstruct cardiac anatomy. This technique also promotes the development of zero-radiation EP procedures. Many EP studies and procedures have implemented ICE because it has several advantages over fluoroscopy and transesophageal echocardiography (TEE). ICE-guided EP procedures can be performed under conscious sedation; esophageal intubation and additional anesthesiologists are not required. Atrial fibrillation (AF) and supraventricular tachycardias (SVT) are the most common tachyarrhythmias in clinical settings. A comprehensive understanding of critical anatomical structures, such as the atrial septum, fossa ovalis (FO), and great heart vessels, is needed for the successful catheter ablation of these arrhythmias.

Hu et al. (2024) conducted a review in Atrial Fibrillation and Supraventricular Tachycardia. Intracardiac Echocardiography (ICE) vs. Fluoroscopy or Transesophageal Echocardiography (TEE) was evaluated. Intracardiac echocardiography improves the safety and efficacy of electrophysiological procedures for atrial fibrillation and supraventricular tachycardia by providing high-resolution real-time visualization.
