Key result
Applying new selection criteria (f-wave >0.1 mV, CTR <70%, LA <70 mm) for the maze procedure during mitral valve surgery significantly improved sinus rhythm restoration (83% vs 55%, P=0.0001).
Why the study?
Does patient selection using specific criteria improve the success rate of sinus rhythm restoration after the maze procedure in patients undergoing mitral valve surgery?

May improve maze success during mitral surgery; hypothesis-generating, needs prospective validation before changing practice.

Does patient selection using specific criteria improve the success rate of sinus rhythm restoration after the maze procedure in patients undergoing mitral valve surgery?
Absolute Event Rate: 83% vs 55%
p-value: p=0.0001
Selecting patients based on f-wave voltage, cardiothoracic ratio, and left atrial dimension significantly improves the success rate of the maze procedure combined with mitral valve surgery.
Kobayashi et al. (1998) conducted a cohort in Atrial fibrillation and mitral valve disease (n=220). Maze procedure with new selection criteria vs. Maze procedure without new selection criteria was evaluated on Sinus rhythm restoration without sick sinus syndrome (p=0.0001). Applying new selection criteria (f-wave >0.1 mV, CTR <70%, LA <70 mm) for the maze procedure during mitral valve surgery significantly improved sinus rhythm restoration (83% vs 55%, P=0.0001).
