Evaluating Virtual Rotor Mapping to Guide Catheter Ablation for Treating Paroxysmal Atrial Fibrillation in Adults

What this Trial Is About

Researchers are evaluating treatments for patients with paroxysmal atrial fibrillation, a type of irregular heartbeat. This study compares traditional catheter ablation guided by a physicians experience with a new method that uses a 3D computer model of the patients heart to guide virtual rotor mapping and additional ablation. The goal is to see if the new method reduces the chance of atrial fibrillation returning after treatment. Participants will be randomly assigned to one of two groups. One group receives catheter ablation based on the physicians personal experience without computer simulation. The other group receives ablation guided by virtual rotor mapping from a patient-specific 3D atrial model, which accounts for individual heart size and shape. Both groups undergo pulmonary vein isolation, with the experimental group receiving extra rotor ablation based on the simulation. During the study, participants will be monitored for up to 24 months after the procedure. Researchers will assess the recurrence of atrial fibrillation over 18 months, as well as rates of mortality, stroke, and hospitalizations over 24 months. They will also track complications such as bleeding, pericardial effusion, and blood transfusion needs. Procedure time and radiofrequency ablation time will be recorded to evaluate treatment efficiency.
