Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with symptomatic atrial fibrillation who undergo AF ablation using the VOLT balloon-in-basket PFA system at participating European centers and can provide informed consent.

Probably not a fit

Patients with left atrial diameter >60 mm, severe mitral valve disease or prior mitral surgery, contraindications to ablation or anticoagulation, intracardiac thrombus, untreated reversible causes of AF, pregnancy, breastfeeding, or active systemic infection are unlikely to be included or to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

A prospective, multi-center European registry will gather all-comer data from high-volume early users of the VOLT balloon-in-basket pulsed-field ablation (PFA) system. The registry will record patient demographics, procedural workflow metrics, safety events, acute efficacy and follow-up outcomes after catheter ablation for symptomatic atrial fibrillation. Learning curve characteristics and comparisons of different workflows across centers will be analyzed. Data collection focuses on real-world adaptation and procedural and follow-up outcomes in routine clinical practice.

Why it matters

Potential benefit: If successful, this approach could offer a faster, more tissue-selective ablation method with improved safety and more streamlined procedural workflows for treating atrial fibrillation.

How similar studies have gone: Other pulsed-field ablation programs and registries have reported promising safety and efficacy signals, but the balloon-in-basket VOLT configuration remains a newer device with limited published real-world data.
