Key result
A concomitant radiofrequency modified Maze procedure resulted in sustained sinus rhythm in 57.1% of patients at latest follow-up, with AF duration and preoperative LA size predicting recurrence.
Cohort (n=285)
In patients with structural heart disease and permanent AF undergoing cardiac surgery, a concomitant RF Maze procedure results in sustained sinus rhythm in over half of patients, with preoperative AF duration and LA size predicting recurrence.

May guide patient selection for concomitant RF Maze; leaves open need for randomized confirmation before practice change.
Beukema et al. (2008) conducted a cohort in structural heart disease and permanent atrial fibrillation (n=285). radiofrequency (RF) modified Maze procedure was evaluated on sustained sinus rhythm (SR) and recurrent AF. A concomitant radiofrequency modified Maze procedure resulted in sustained sinus rhythm in 57.1% of patients at latest follow-up, with AF duration and preoperative LA size predicting recurrence.
