It is difficult to evaluate the efficacy of maze procedures because a true atrial fibrillation (AF) burden measurement during follow-up is not yet clinically available. The aim of this study is to evaluate the usefulness of early postoperative AF burden as a predictor of late AF recurrence after the maze procedure.
Between January 2000 and November 2009, we enrolled 508 consecutive patients (284 females, aged 55 ± 12 years) who underwent the maze procedure with other cardiac operations. The early postoperative AF burden was measured by continuous monitoring of the cardiac rhythm during hospitalization. The post procedural rhythm was checked with a serial electrocardiogram every year. The mean follow up duration was 58 ± 32 (maximum, 10.4 years) months.
Variables correlated with early postoperative atrial fibrillation burden
Atrial fibrillation duration (month)
Atrial fine F wave (<1 mm)
Left atrial volume index (ml)
Measurement of the early postoperative AF burden was helpful in predicting AF recurrence. We suggest that greater efforts to prevent AF recurrence should be made in patients with high early postoperative AF burden and long AF duration.
