About this study
VITAL is a prospective, single arm, multicenter, interventional study to evaluate the safety and effectiveness of the VytronUS Ablation System (VAS) for the treatment of symptomatic paroxysmal atrial fibrillation (PAF) using low intensity collimated ultrasound (LICU) for imaging and ablation.
Read the detailed description
Patients undergoing elective catheter ablation for symptomatic PAF who are refractory or intolerant to at least one antiarrhythmic drug (Class I-IV) will be screened for enrollment. Patients who meet the study entry criteria and sign the patient informed consent form will be enrolled and treated consistent with the 2012 Heart Rhythm Society (HRS)/European Heart Rhythm Association (EHRA)/European Cardiac Arrhythmia Society (ECAS) Expert Consensus Statement on Catheter and Surgical Ablation for Atrial Fibrillation. Eligible patients will receive treatment with the VAS including ultrasound imaging of the left atrium and cardiac ablation to electrically isolate the pulmonary veins.
Up to 100 patients will be enrolled at up to 10 sites in Europe (EU) and in the United States (US).

Questions about this trial
What is this clinical trial studying?
A study testing VytronUS Ablation System in people with Paroxysmal Atrial Fibrillation, run by VytronUS, Inc. at 1 site in Czechia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 May 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Director Clinical Affairs (+1 408 730 1333, davidh@vytronus.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Primary Safety: Incidence of early-onset serious adverse events (time frame: 7 days or discharge, whichever is sooner). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2018; AzTrials last refreshed its copy on 8 Nov 2026.
