Assessing Epicardial Substrate Using Intracardiac Echocardiography During VT Ablation.

The article presents a research study on the assessment of epicardial substrate through the use of intracardiac echocardiography (ICE) during ablation of ventricular tachycardia (VT). It examines whether ICE can detect abnormal epicardial substrate in nonischemic cardiomyopathy (NICM) and VT patients. The study reveals that ICE imaging can identify increased echogenicity in the left ventricular (LV).
