Nonrobust meta-analysis findings warrant caution on concomitant maze; larger RCTs needed to confirm stroke benefit versus pacemaker risk.
Does a simultaneous maze procedure reduce the risk of stroke or death in patients with chronic or paroxysmal atrial fibrillation who receive mitral valve surgery?
Weak evidence suggests a simultaneous maze procedure during mitral valve surgery may reduce stroke risk but increase pacemaker need, highlighting the need for larger RCTs.
