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

Eligibility Criteria

• * Patient is planned for a catheter ablation procedure to ablate either:
• * Premature ventricular contractions (PVCs) and a class I or IIa indication for catheter ablation of PVCS according to the 2019 HRS/EHRA/APHRS/LAHRS guidelines
• * Symptomatic Sustained Monomorphic Ventricular Tachycardia
• * Able and willing to provide written consent and comply with all testing and follow-up requirements
• * Above 18 years of age
• * Documented intracardiac thrombus or (if this can be dissolved with anticoagulation, the patient would then be eligible to participate)
• * Contraindication to anticoagulation
• * Life expectancy or other disease processes likely to limit survival to less than 12 months.
• * Currently enrolled in an investigational study evaluating another device, biologic, or drug, that would interfere with this trial.
• * NYHA Class IV heart failure
• * Severe, untreated coronary artery disease which would preclude infusion of provocative agents
• * Severe aortic stenosis (AVA \< 1.0cm, or PG \> 64mmHg)
• * Severe mitral regurgitation.
• * Allergy to contrast which is unable to be adequately pre-medicated.
• * Acute non-cardiovascular illness or systemic infection
• * Thrombocytopenia (platelet count \< 50,000/mm3) or coagulopathy unless corrected
• * Cardiogenic shock unrelated to ventricular arrhythmias
• * Pregnancy or anticipated pregnancy during study follow-up
• * PVCs or VT, which are felt to be secondary to electrolyte imbalances active thyroid disease or any reversible non-cardiac cause.
