This report examines the long-term effects of intraoperative RFA in the prevention of recurrence of AF when used as an adjunctive treatment in patients undergoing cardiac procedures for primary indications unrelated to their arrhythmia.Methods: The study reviewed the records of patients from a tertiary medical center which had 2 cardiac surgeons performing an intraoperative adjunctive RFA procedure. A total of 20 patients undergoing RFA between April 11, 2003 and May 10, 2005 were included and followed for up to 10years. The primary effectiveness outcome of the study was the recurrence of AF during the follow-up period. Data were collected from office or hospital medical records.Results: A total of 20 patients were included (mean age 69.4years, males 40%). Eight patients were followed for 10years and 2 patients for 9years; 7 patients died during the 10-year follow-up period and 3 patients were lost to follow-up. As their primary procedures, the patients underwent valve surgery (65%), bypass surgery (15%), or both (20%). Intraoperative RFA failed to restore sinus rhythm in 2 patients. In the remaining 18 patients, AF recurred in 10 patients within 2months of surgery, in 1 patient at 5months, in 1 patient at 7months, and in 6 patients after 1year.Conclusion: AF had recurred in 100% of patients by the end of the long-term follow-up period. The adjunctive intraoperative RFA and postoperative interventions employed in this early study failed to maintain sinus rhythm.
