Key result
Ultrasound catheter ablation achieves 5-9 mm lesion depths in preclinical models.
Why the study?
The feasibility of using ultrasound to induce cardiac tissue necrosis for arrhythmia treatment was investigated due to the need for alternative ablation methods.
Does ultrasound ablation induce adequate cardiac tissue necrosis in canine heart muscle models?
Does ultrasound ablation induce adequate cardiac tissue necrosis in canine heart muscle models?
Ultrasound ablation is feasible for inducing adequate cardiac tissue necrosis in preclinical models, demonstrating potential for the treatment of arrhythmias.

Does not support clinical use; leaves open translation to human arrhythmia ablation.
Zimmer et al. (1995) studied Arrhythmias. Ultrasound for cardiac ablation was evaluated on Cardiac tissue necrosis and lesion depth. Ultrasound catheters successfully induced cardiac tissue necrosis in canine models, achieving in vivo lesion depths of 5-9 mm, indicating potential for treating arrhythmias.
