Background: We aimed to reduce atrial fibrillation and thromboembolic events by reducing left atrial dilatation via posterior plication technique.

Methods: Between May 2003 and January 2009, 38 patients (17 males, 21 females; mean age 53.7±9.9 years; range 44 to 76 years) underwent mitral valve surgery with left atrial reduction by posterior wall plication. Neither bipolar nor unipolar catheter ablation therapy for chronic atrial fibrillation (AF) was performed in this study. We also did not include patients in this study who had undergone radiofrequency ablation therapy for chronic AF.

Results: At discharge, 15 patients (39%) were in sinus rhythm. During follow-up, sinus rhythm was restored in 14 patients (37%). Left atrium diameter was significantly reduced from 7.0±1.4 cm preoperatively to 4.6±0.5 cm at six months after surgery.

Conclusion: In conclusion, left atrial size reduction is simple, takes less time, and is also effective in maintaining sinus rhythm without adding any additional mortality or morbidity compared to mitral valve surgery alone.
