The VERITAS VT Study is a prospective, multicenter, international, single-arm clinical investigation designed to evaluate the safety and effectiveness of the FieldForce™ Pulsed Field Ablation System for the treatment of sustained monomorphic ventricular tachycardia (VT). Eligible patients undergoing catheter ablation for VT will receive treatment with the investigational pulsed field ablation system according to the study protocol.
The study will assess acute and chronic outcomes including major adverse events, freedom from recurrent ventricular tachycardia, need for antiarrhythmic drug escalation, repeat ablation procedures, and other clinically relevant outcomes through 180 days following the index ablation procedure.
Ventricular tachycardia remains a significant source of morbidity and mortality among patients with structural heart disease. Although catheter ablation is an established therapeutic option, long-term recurrence rates remain substantial and procedural challenges continue to exist.
The VERITAS VT Study is a prospective, multicenter, single-arm clinical investigation evaluating the safety and effectiveness of the Field Force Pulsed Field Ablation System in subjects with sustained monomorphic ventricular tachycardia. Eligible participants will undergo mapping and ablation using the Field Force Pulsed Field Ablation System during the index procedure. Subjects will be followed for 180 days after the index procedure to assess safety and effectiveness outcomes.
The primary safety objective is to evaluate the incidence of device- and procedure-related major adverse events. The primary effectiveness objective is to evaluate freedom from recurrence of sustained monomorphic ventricular tachycardia through 180 days following the index ablation procedure

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Participants will undergo ventricular tachycardia ablation using the Field Force Pulsed Field Ablation System during the index procedure.
Device: System is an investigational catheter-based device designed to deliver pulsed field ablation energy to cardiac tissue for the treatment of sustained monomorphic VT
The Field Force Pulsed Field Ablation System is an investigational device that delivers non-thermal pulsed electric field energy through a catheter-based platform to ablate targeted cardiac tissue. The system is intended for use during catheter ablation procedures in patients with sustained monomorphic ventricular tachycardia (VT) to treat tissue involved in the initiation and maintenance of the arrhythmia.
Primary Safety Endpoint - Freedom from casual or probable device or procedure related Major Adverse Events (MAEs) that occur within 7 days following the ablation procedure. (Or within 90 days for esophageal events (fistula/perforation)
A pre-defined list of device - or procedure-related MAEs, as adjudicated by the Clinical Events Committee (CEC), occurring within 7 days after the index ablation procedure (or within 3 months after the index ablation procedure for any esophago-pericardial fistula/esophageal perforation) will be considered a primary safety event
Time frame: As applicable within 7 days or 90 days after the index ablation procedure
Primary Effectiveness: Freedom from recurrence of sustained monomorphic VT
Freedom from recurrence of sustained monomorphic VT (MMVT) in the absence of new or increased dose of Class I or III antiarrhythmic drugs (AAD) for any ventricular arrhythmia through 6 months after the index ablation procedure
Time frame: Through 6 months most the index ablation procedure
Secondary Effectiveness Endpoint: Percentage of patients with reduced ventricular tachycardia burden
Percentage of patients with reduced ventricular tachycardia burden
Time frame: 6 months post index procedure
