ABSTRACT

Objective:

To evaluate the long-term results of combined ganglion plexus ablation(GPA) during radiofrequency ablation(RF) with long-standing persistent atrial fibrillation(LSP-AF).

Methods:

This retrospective study sample consisted of 268 patients with LSP-AF underwent valve operations concomitant RF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events. Propensity score matching conducted by RF and RF+ GPA resulted in 102 patients per group.

Results:

Independent predictors for rhythm success at 1 year were combined GPA( OR=0.205, P=0.005), smaller left atrium size( OR=1.091, P=0.000); at 5-year and 8-year were a shorter history of AF( OR=1.069, P=0.023; OR=1.066, P=0.030), and smaller left atrium size( OR=1.091, P=0.000; OR=1.086, P=0.000). After matching, RF+ GPA group had significantly higher sinus rhythm(SR) without antiarrhythmic drugs(AADs) at 6 months(91.3% vs. 79.8%, P=0.026), 1-year(90.2% vs. 78.5%, P=0.028), but there were no difference between the two groups at 5-year(64.8% vs. 64.4%, P=0.956), and 8-year(53.3% vs. 50.6%, P=0.711). During the 6 postoperative months, fewer patients in the RF+ GPA group underwent follow-up cardioversions(2.0% vs. 8.8%, P=0.030). Actuarial survival curves did not differ significantly between the 2 groups( HR=1.327, 95% CI 0.4633-3.802, P=0.598).

Conclusion:

The combination of GPA can be effective at the early postoperative stage for SR restoration in Maze Ⅳ procedures for the treatment of LSP-AF in heart valve surgeries, particularly for lower AADs use and lower cardioversions. However, this effect will gradually diminish after one year.
