Hypothesis
Can radiofrequency ablation effectively treat permanent atrial fibrillation during cardiac surgery?
Conclusion
Radiofrequency ablation combined with amiodarone therapy is a safe and effective method to cure permanent atrial fibrillation in patients undergoing open heart surgery.
Supporting Evidence
- 75% of patients had stable sinus rhythm at late follow-up.
- Almost 90% of patients with a preoperative left atrial diameter of less than 56mm achieved stable sinus rhythm.
- The study included 62 patients who underwent surgical ablation procedures.
Takeaway
Doctors can use special heat to fix a heart problem called atrial fibrillation during surgery, helping many patients feel better.
Methodology
Monopolar and bipolar radiofrequency ablation procedures were performed on patients with permanent atrial fibrillation during heart valve surgery.
Limitations
Follow-up data were only evaluated using 12-lead ECG, and the study was not conducted under randomized conditions.
Participant Demographics
Patients undergoing heart valve surgery with a mean left atrial diameter of 55.6±7.3 mm.
