Brief Summary:
ASCEND is a randomized controlled open-label pilot study evaluating the safety and effectiveness of pulsed field ablation (PFA) with the novel FARAPOINT catheter compared to the standard radiofrequency (RFA) ablation with ThermoCool ST/FlexAbility SE/ThermoCool ST SF/TactiFlex SE of ventricular tachycardia (VT) in the patients with ischemic cardiomyopathy and implantable cardioverter-defibrillator (ICD). The study hypothesis is that the PFA ablation is more efficient compared to the RFA technique but retains a comparable safety profile.
Detailed Description:
The ASCEND trial is a pilot study that will test the hypothesis that the novel FARAPOINT catheter and the FARAPULSE PFA platform can accomplish ischemic substrate VT ablation more efficiently and with a similar safety profile compared to a contemporary, widely adopted RFA technology (ThermoCool ST/FlexAbility SE/ThermoCool ST SF/TactiFlex SE).
ASCEND is a single center, controlled (two-arm), 1:1 parallel-randomized, open-label pilot study of 40 consecutively enrolled patients with ischemic cardiomyopathy and drug refractory or drug intolerant VT in whom a catheter ablation procedure is indicated. The study intervention consists of the use of a novel FARAPOINT PFA catheter during the entire VT ablation procedure. Patients randomized to the control arm of the study will undergo VT ablation using a contemporary standard-of-care technology (ThermoCool ST/FlexAbility SE/ThermoCool ST SF/TactiFlex SEcatheters).
This pilot study is designed to test for superiority with respect to the primary efficacy metric and to ensure comparable safety profiles of both ablation methods.
