Key result
Real-time intracardiac ultrasound mapping correlated more accurately with electroanatomic mapping for left ventricular scar identification than transthoracic echocardiography (86% vs 80%, P=0.046).
Why the study?
Does real-time intracardiac ultrasound (ICE) mapping accurately identify scar tissue compared to electroanatomic mapping and TTE in patients undergoing VT ablation?
Observational (n=18)
Does real-time intracardiac ultrasound (ICE) mapping accurately identify scar tissue compared to electroanatomic mapping and TTE in patients undergoing VT ablation?
Absolute Event Rate: 86% vs 80%
p-value: p=0.046
Real-time intracardiac ultrasound provides accurate left ventricular scar boundaries that correlate better with electroanatomic mapping than transthoracic echocardiography during VT ablation.

ICE may improve LV scar identification accuracy versus TTE during VT ablation; leaves open prospective outcome validation.
Bunch et al. (2010) conducted an observational in Ventricular tachycardia (n=18). Real time intracardiac ultrasound (ICE) mapping vs. Transthoracic echocardiography (TTE) and electroanatomic mapping (CARTO) was evaluated on Correlation of scar identification with electroanatomic mapping in left ventricular wall segments (p=0.046). Real-time intracardiac ultrasound mapping correlated more accurately with electroanatomic mapping for left ventricular scar identification than transthoracic echocardiography (86% vs 80%, P=0.046).
