Novel case of linear ultra-low cryoablation catheter for treatment of ventricular tachycardia

Key Teaching Points•Understand how new technologies can increase efficacy of ventricular tachycardia (VT) ablation. Novel technologies are focused on achieving the increased tissue depth required for VT ablation.•Lesion depth matters. Ultra-low-temperature cryoablation has the advantage of being able to titrate lesion depth according to tissue thickness in a given region.•In the near future, we will be able to choose between different technologies for VT ablation. Ultra-low-temperature cryoablation could be a useful ablation tool, creating deeper ventricular lesions compared to conventional radiofrequency. Studies assessing its safety and feasibility are ongoing. •Understand how new technologies can increase efficacy of ventricular tachycardia (VT) ablation.
