“…Nevertheless, limited data are available on its use for ventricular arrhythmias, particularly in nonidiopathic and nonischemic etiology. 7 , 10 According to the distribution of the arrhythmogenic substrate in patients with nonischemic cardiomyopathy, RF ablation is associated with higher recurrence rates than in those with ischemic etiology. 2 In our current report, we examined the cryothermal ablation depth following the procedure using a CMR scan to compare it to the preablation status.…”

“…Furthermore, its acute efficacy and safety has been reported in 13 patients with predominantly ischemic cardiomyopathy and extensive scar area. 7 , 8 Contrary to ischemic cardiomyopathy, where the arrhythmogenic substrate is primarily distributed subendocardially, the substrate for VT in patients with nonischemic cardiomyopathy is thought to be much more diffuse, rarely compact, and primarily localized deep within the myocardium. 9 In this report, we present a case of the utilization of the ULTC technology in a patient with nonischemic cardiomyopathy.…”

Radiofrequency (RF) catheter ablation is the first-line modality for ventricular tachycardia (VT) ablation. Yet, recurrence rates of scar-related VTs are substantial, particularly in the complex and heterogenous nonischaemic cardiomyopathies. To address the still unmet need of delivering durable lesions to all functionally critical areas, including in conventionally inaccessible (e.g. deep mid-myocardial) or prohibitive areas (e.g. proximity to coronaries), a number of alternative interventional approaches have been proposed. Multiple reviews have summarized advanced RF strategies of how to target challenging VT substrates, but the spectrum for ablation modalities to treat ventricular arrhythmias is also rapidly growing beyond the well-established RF technology. Alternative energy sources and delivery modes to treat ventricular arrhythmias include ultra-low temperature cryoablation, pulsed field ablation, laser ablation, high-intensity focused ultrasound ablation and shock wave ablation. Stereotactic body radiation, chemical ablation with ethanol and autonomous nervous system modulation are further promising technologies to reduce arrhythmia burden. The wide variety of emerging approaches and techniques offers new opportunities to select tailored VT ablation strategies based on the individual substrate and VT characteristics. This review aims to present rational and evidence of emerging and cutting-edge non-RF VT ablation technologies to provide the reader with a compact update of this rapidly evolving field of cardiac electrophysiology. This will be complemented by a discussion about the specific VT substrates for which the individual technologies may prove to be most useful.
