Key result
High-intensity focused ultrasound (HIFU) at 400 W for 2-4 seconds successfully terminated pacing-induced ventricular tachycardia in 5 experimental dog preparations without collateral tissue injury.
Why the study?
Does high-intensity focused ultrasound (HIFU) allow for noninvasive ablation of targeted ventricular myocardium in a canine model?
Does high-intensity focused ultrasound (HIFU) allow for noninvasive ablation of targeted ventricular myocardium in a canine model?
HIFU is a feasible modality for noninvasive, targeted ablation of ventricular myocardium in a preclinical model, suggesting potential utility for VT ablation.

HIFU terminates VT noninvasively in dogs without injury; leaves open translation to human VT ablation pending trials.
Lü et al. (2018) studied Ventricular tachycardia (n=5). High-intensity focused ultrasound (HIFU) ablation was evaluated on Loss of ventricular capture and electrical nonexcitation. High-intensity focused ultrasound (HIFU) at 400 W for 2-4 seconds successfully terminated pacing-induced ventricular tachycardia in 5 experimental dog preparations without collateral tissue injury.
