简要总结
This study evaluates whether re-sterilized (reprocessed) ablation catheters are as effective and safe as new ablation catheters when used for electrophysiological procedures. 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.
详细描述
This is a prospective, randomized, controlled non-inferiority trial comparing re-sterilized (reprocessed) and new ablation catheters in electrophysiological procedures. The study will be conducted at University Hospital Dubrava, a high-volume tertiary center for cardiac electrophysiology.
Patients scheduled for electrophysiological procedures 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 groin puncture to completion of ablation. 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 ablation, the number of energy applications 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 before and after the procedure to assess potential infectious complications.

研究组 & 干预措施
Reprocessed Catheter (Experimental)
Participants will undergo electrophysiological procedure (ablation) using a reprocessed ablation catheter. The catheter has undergone validated cleaning, re-sterilization, and functional testing in accordance with applicable regulatory and safety standards. Procedural technique, energy delivery protocol, and peri-procedural management will be identical to those used in the comparator arm.
干预措施: Ablation - reprocessed (Procedure)
New Catheter (Active Comparator)
Participants will undergo electrophysiological procedure (ablation) using a new ablation catheter. Procedural technique, energy delivery protocol, and peri-procedural management will be identical to those used in the comparator arm.
干预措施: Ablation - new (Procedure)
