Abstract

Intracardiac echocardiography (ICE) allows intraprocedural assessment of cardiac anatomy and identification of ischemic myocardial scar and is useful for guidance of the ablation catheter and monitoring for complications. In this review, the authors discuss and provide examples of how ICE can be used to obtain additional information to understand arrhythmia mechanisms and facilitate catheter ablation therapy for ventricular arrhythmias arising from ischemic scar substrates.

Keywords: Catheter ablation; Intracardiac echocardiography; Ischemic cardiomyopathy; Ventricular arrhythmias.
