Five-year results of a modified left atrial maze IV procedure in the treatment of atrial fibrillation: a randomized study.

ABSTRACT:

Background

The left atrial maze IV (LAM-IV) alone has been used to eliminate atrial fibrillation (AF) without severe right heart diseases. However, we felt that it could be improved and developed a modified LAM-IV (MLAM-IV). In this prospective trial, we aimed to investigate 5-year clinical outcomes of AF in patients treated by the novel MLAM-IV technique.

Methods

Between September 2012 and October 2013, 120 patients who underwent valve surgery and bipolar radiofrequency ablation for AF were randomized into the LAM-IV group (n = 60) or MLAM-IV group (n = 60). At postoperative follow-up examinations, data were recorded at 1, 3 and 6 months, and annually thereafter.

Results

The mean ablation time and postoperative ventilation time were shorter in the MLAM-IV group than
