Reprocessed versus new ablation catheters for pulmonary vein isolation

Official title: Feasibility, Safety, Cost-effectiveness, and Environmental Impact of Reprocessed Ablation Catheters in Pulmonary Vein Isolation

Run by University Hospital Dubrava · NCT07389434 · Data updated 2026-11-12

This will test whether re-sterilized (reprocessed) ablation catheters work as well and are as safe as new catheters for adults having pulmonary vein isolation for atrial fibrillation.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with paroxysmal or persistent atrial fibrillation who have an indication for pulmonary vein isolation and can give informed consent are ideal candidates.

Probably not a fit

Patients with severe valvular disease, significant structural heart disease that precludes pulsed field ablation, pregnancy, breastfeeding, or life expectancy under 12 months are unlikely to benefit from participation.

What this trial studies

This is a prospective, randomized, controlled non-inferiority trial at a high-volume tertiary center comparing reprocessed and new electroporation ablation catheters for pulmonary vein isolation. Adult patients with paroxysmal or persistent atrial fibrillation scheduled for PVI are randomized 1:1 to undergo pulsed field ablation with either a new or a reprocessed catheter using identical procedural techniques. The study records procedure duration, ablation delivery metrics, fluoroscopy time and dose, catheter performance measures, peri- and post-procedural adverse events, and laboratory inflammation markers. It also compares costs and environmental impact metrics between the two approaches.

Why it matters

Potential benefit: If reprocessed catheters perform similarly to new ones, patients could benefit from lower procedure costs and reduced medical waste without loss of safety or effectiveness.

How similar studies have gone: Reprocessing of some medical devices has been studied previously, but randomized non-inferiority data specifically for reprocessed electroporation (PFA) ablation catheters are limited.
