“…Huang and colleagues present ex vivo data on a novel, "focused electrical field" technology that consists of a geometrically focused tip that attaches onto an existing RF catheter and collimates the beam, achieving 14-mm deep lesions without increase in steam pops [14]. I look forward to in vivo data from this group, as do Tschabrunn and Frankel, who nicely comment on this study in their editorial [15]. Lastly, Aras and colleagues add to the growing body of literature on VT stereotactic body radiation therapy (SBRT) with their single-center study of 8 patients in whom suppression of VT seemed most prominent in the first 3 months post-SBRT, with questionable long-term efficacy [16].…”

“…Potential limitations of the current design are the requirement for perpendicular tip-tissue orientation and potential collateral thermal injury due to larger lesion size. [ 71 ] Studies are being conducted to characterise the biophysics in scarred myocardium; investigate applicability for epicardial ablation; validate its effectiveness in a beating heart; and investigate its use as a PFA delivery source.…”

Ventricular tachycardia (VT) is a significant cause of morbidity and mortality in patients with ischaemic and non-ischaemic cardiomyopathies. In most patients, the primary strategy of VT catheter ablation is based on the identification of critical components of reentry circuits and modification of abnormal substrate which can initiate reentry. Despite technological advancements in catheter design and improved ability to localise abnormal substrates, putative circuits and site of origins of ventricular arrhythmias (VAs), current technologies remain inadequate and durable success may be elusive when the critical substrate is deep or near to critical structures that are at risk of collateral damage. In this article, we review the available and potential future non-surgical investigational approaches for treatment of VAs and discuss the viability of these modalities.
