Treatment of Focal Ventricular Tachycardias Using a Pulsed Field Ablation From a Point Ablation Catheter Short Title FOCUS-PFA

Study Design - This is a prospective, single-center, single-arm clinical pilot study to assess the safety and effectiveness of ablation of focal ventricular arrhythmias using the Farapoint catheter. Sample Size - A total of 30 subjects will be included in this study. All patients will undergo treatment with the study PFA catheter. Study Population - The target population is subjects who are planned to undergo a clinically-indicated ablation procedure for managing their focal ventricular arrhythmias - premature ventricular contractions or ventricular tachycardias. Study Duration - Approximately 12 months: 3 months site start-up, 6 months enrollment and 3 months of follow up. Participant Duration - Subjects will undergo brief pre-procedural testing, the ablation procedure, and 3 months of post-procedural follow up. Primary Effectiveness Endpoint Chronic Single-Procedure Success: defined as a reduction in the burden of premature ventricular contracts (\>80%) for patients treated for PVCs or absence of sustained focal ventricular tachycardia for patients being treated for focal VTs without an increase in anti-arrhythmic medications at 3 month follow ups.
