About this study

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

This study evaluates whether re-sterilized (reprocessed) ablation catheters are as effective and safe as new ablation catheters when used for pulmonary vein isolation in patients with atrial fibrillation. Adult patients scheduled for catheter ablation will be randomly assigned to undergo the procedure using either a new catheter or a re-sterilized catheter, with identical procedural techniques applied in both groups. The study will compare procedural efficiency, safety, costs, and environmental impact between the two approaches. The results may support more sustainable and cost-effective use of medical devices in cardiac electrophysiology.

Read the detailed description

This is a prospective, randomized, controlled non-inferiority trial comparing re-sterilized (reprocessed) and new ablation catheters for pulmonary vein isolation in patients with atrial fibrillation. The study will be conducted at University Hospital Dubrava, a high-volume tertiary center for cardiac electrophysiology.

Patients scheduled for pulmonary vein isolation will be randomized in a 1:1 ratio using a computer-generated sequence to undergo ablation with either a new or a re-sterilized catheter. All procedures will be performed by experienced electrophysiologists in accordance with standard institutional practice.

Procedure duration will be measured from transseptal puncture to completion of ablation of all pulmonary veins. Additional procedural parameters related to ablation delivery, including duration and number of energy applications, total ablation time, and other procedural timing characteristics, will also be recorded. Fluoroscopy time and radiation dose, expressed as dose-area product (DAP), will be recorded automatically.

Catheter performance will be assessed based on achievement of complete pulmonary vein isolation, the number of energy applications per pulmonary vein, and procedural assessment of catheter integrity, flexibility, and electrical properties.

Procedural safety will be evaluated by monitoring peri-procedural and post-procedural adverse events, including pericardial effusion, stroke, vascular complications, and death. Laboratory markers of inflammation, infection, and hemolysis will be obtained at predefined time points before and after the procedure. Blood cultures will be collected after the procedure to assess potential infectious complications.

Patients will be followed clinically during hospitalization and after discharge through telephone contact and routine outpatient visits.

Economic evaluation will include direct procedural costs, catheter costs, and re-sterilization costs. Environmental impact will be assessed based on medical waste generation and estimated carbon footprint associated with catheter use.

Re-sterilization of ablation catheters will be performed according to the validated internal protocol of University Hospital Dubrava, which has been used in routine clinical practice.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Participants will undergo pulmonary vein isolation using pulsed field ablation (PFA). The intervention consists of the use of either a reprocessed electroporation ablation catheter or a new electroporProcedure or surgery

    This intervention involves pulmonary vein isolation performed with ablation catheter that is either new or reprocessed. The reprocessed catheter has undergone validated cleaning, resterilization, and functional testing in accordance with regulatory and safety standards prior to reuse. The key distinguishing feature of this intervention is the comparison of reprocessed versus new single-use catheters, while all other procedural aspects, including operator technique, energy delivery protocol, and peri-procedural care, are standardized and identical between groups.

Model description
The study is designed as a prospective, randomized, controlled non-inferiority trial with a parallel-group design, comparing resterilized (reprocessed) and new electroporation ablation catheters used for pulmonary vein isolation in patients with atrial fibrillation. Participants will be randomly assigned to two groups, with one group undergoing ablation using new catheters and the other using resterilized catheters, while the procedural protocol will be identical in both groups. The primary endpoint is procedure duration, expressed in minutes. Secondary endpoints include catheter functionality, fluoroscopy time and radiation dose, peri- and post-procedural complications, procedural safety, procedural costs, and assessment of environmental impact.
