Understanding the scope of intracardiac echocardiography in catheter ablation of ventricular arrhythmia

Abstract

Over the last few decades, catheter ablation has emerged as the first-line treatment for ventricular arrhythmias. However, detailed knowledge of cardiac anatomy during the surgery remains the prerequisite for successful ablation. Intracardiac echocardiography (ICE) is a unique imaging technique, which provides real-time visualization of cardiac structures, and is superior to other imaging modalities in terms of precise display of cardiac tissue characteristics as well as the orientation of anatomical landmarks. This article aimed to introduce the various advantages and limitations of ICE in the ablation of ventricular arrhythmias.

Long-Term Outcomes of Catheter Ablation for Ventricular Arrhythmias: Comparing Techniques with and without Intracardiac Echocardiography - What Matters?

“…ICE with three-dimensional electroanatomical mapping is increasingly utilized in the management of ventri-cular arrhythmias 14 . Although there is a paucity of evidence regarding its safety and efficacy for PVCs, our study sought to examine the associated complications and both the acute and long-term success of PVC CA with and without ICE.…”

Intracardiac echocardiography is a promising strategy for guiding closure of the left atrial appendage

“…ICE-guided cardiac imaging modalities usually involve placing a catheter in the right ventricle (RV), right atrium (RA), or left atrium (LA). 12 Two other unusual catheter-placement techniques, coronary sinus echocardiography (CSE) and percutaneous intrapericardial echocardiography (IPE), are rapidly being developed and will have a tiny space in the area of EP.…”

“…Because it provides near‐field, high‐quality, real‐time assessment of cardiac anatomy, 11 ICE has gradually come to be used to guide cardiac interventional therapy and guard against complications. ICE‐guided cardiac imaging modalities usually involve placing a catheter in the right ventricle (RV), right atrium (RA), or left atrium (LA) 12 . Two other unusual catheter‐placement techniques, coronary sinus echocardiography (CSE) and percutaneous intrapericardial echocardiography (IPE), are rapidly being developed and will have a tiny space in the area of EP.…”

CSE involves the use of catheter‐based ultrasound, specifically, the introduction of an ICE catheter into the coronary sinus (CS), while, in IPE, an ICE catheter is introduced into the pericardial space.…”
