The Effect of Mechanical Ventilation on Radiofrequency Ablation in the Treatment of Atrial Fibrillation

What this Trial Is About

Researchers are investigating how different mechanical ventilation methods affect the success of radiofrequency ablation (RFA) in treating atrial fibrillation (AF). RFA is performed under general anesthesia, and the procedure's success depends on stable and safe contact between the catheter electrode and heart muscle. Movement caused by breathing can reduce catheter stability, leading to less effective treatment and higher chances of AF returning. Although some ventilation methods like high-frequency jet ventilation have shown promise in improving catheter stability and reducing AF recurrence, no clear evidence currently exists about which ventilation mode is best during RFA. The study compares two mechanical ventilation strategies used during RFA under general anesthesia: Flow Controlled Ventilation (FCV) and Volume Controlled Ventilation (VCV). Participants receive radiofrequency ablation for AF while connected to one of these ventilation modes. The hospital's equipment supports various ventilation types, but high-frequency jet ventilation is not available. The goal is to see if one ventilation method improves the procedure by enhancing catheter contact and stability. Participants will be monitored during and after the ablation procedure. Key outcomes measured include the duration of the ablation procedure, changes in electrocardiography at the procedure's end, and the rate of atrial fibrillation recurrence one month after treatment. Researchers will assess these factors to determine how ventilation affects ablation effectiveness and safety. The entire evaluation focuses on treatment success and patient outcomes following the procedure.
