Patient-reported quality of life after stand-alone and concomitant arrhythmia surgery: a systematic review and meta-analysis.

In patients with AF, QOL improves after both stand-alone and concomitant arrhythmia surgery. In the concomitant group, this improvement can be attributed to both the cardiac procedure itself as well as the add-on arrhythmia surgery. However, both in stand-alone and concomitant procedures, the improvement in QOL seems to be related to the effectiveness of the procedure to maintain sinus rhythm after 12 months.
