BACKGROUND: Ebstein anomaly (EA) is commonly associated with atrial flutter or fibrillation (AFl/F), which adversely affects outcome. Surgical ablation of AFl/F during surgery for EA has been shown to be effective, but the optimal lesion set remains unknown.
METHODS: Between 1995 and 2010, 86 patients had corrective surgery for EA and concomitant maze procedure for associated AFl/F. Median age at operation was 40 years (range, 1 to 72 years), and 49 patients (60%) were male. Preoperative AFl/F was paroxysmal in 43 patients (50%). All patients who had diagnosis of or treatment for accessory pathways and reentrant tachycardia were excluded from this analysis.
RESULTS: All patients underwent tricuspid valve surgery for EA and concomitant maze procedure, including right-sided maze (RSM) in 62 patients (72%) and biatrial maze (BAM) in 24 patients (28%). Early mortality occurred in 3 patients (3.5%). During median follow-up of 52 months (range, 3 months to 17 years), overall freedom from AFl/F without antiarrhythmic medications was 79% (RSM, 80% versus BAM, 76%; p = 0.97). Although there was no difference in rhythm outcome between RSM and BAM for patients with paroxysmal AFl/F (p = 0.08), there was a trend toward higher freedom from AF without antiarrhythmic medications in patients with persistent AFl/F for BAM (86%) versus RSM (71%; p = 0.053). Overall, there were no late strokes, and 84% were free from sodium warfarin anticoagulation.
CONCLUSIONS: Overall, surgical ablation of preoperative AFl/F is effective in patients undergoing surgery for EA. Although rhythm outcome of RSM and BAM did not differ in patients with preoperative paroxysmal AFl/F, those with persistent or permanent AFl/F may benefit from a biatrial lesion set.
