Key result
Contact sensing guided high-intensity ultrasound achieves 100% lesion efficiency versus standard ultrasound in swine.
Why the study?
High-intensity ultrasound ablation has been limited by directional transducer orientation, resulting in inconsistent myocardial targeting with low lesion efficiency and transmurality.
Contact sensing may enhance high-intensity ultrasound lesion efficiency; extends preclinical data but leaves clinical translation open.

Morris et al. (2026) studied Ventricular tachycardia and hypertrophic cardiomyopathy (swine model) (n=23). Contact sensing guided high-intensity ultrasound (CSG-HIU) vs. Standard high-intensity ultrasound (Std-HIU) was evaluated on Lesion efficiency (p=0.007). Contact sensing guided high-intensity ultrasound improved lesion efficiency compared to standard ultrasound (100% vs 50%, p=0.007) in a terminal swine model.
