ABSTRACT
Objective:
To evaluate the long-term results of bipolar radiofrequency(BRF) ablation in restoring sinus rhythm in patients with permanent atrial fibrillation(AF) undergoing surgery for cardiac surgery.Methods:
This retrospective study sample consisted of 268 patients with LSP-AF underwent cardiac operations concomitant BRF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events.Results:
15 patients died in the early postoperative period, perioperative mortality rate was 5.5%. The rate of stable sinus rhythm(sSR)was 86.6%, 75.4%, 67.7%, 57.8% in 1, 2, 5, 8 years after operation. Multivariate analysis proved the size of the left atrium( HR=1.073, P<0.001) and duration of AF( HR=1.070, P=0.025) to be an independent predictor of the radiofrequency ablation outcome.Conclusion:
Bipolar radiofrequency maze procedure can effectively eliminate AF, maintain long-term of sinus rhythm. Bipolar radiofrequency maze procedure is a safe, easy and effective surgical option for the treatment of AF, with satisfactory long-term results, is worthy of promotion.
