Key result
The Maze procedure in patients with non-mitral valvular atrial fibrillation achieved a 57% freedom from atrial fibrillation at 500 days, comparable to the 61% rate in patients with mitral valve disease.
Why the study?
Does the Maze procedure provide similar freedom from atrial fibrillation in patients without mitral valve disease compared to those with mitral valve disease?
Cohort (n=107)
No

Absolute Event Rate: 57% vs 61%
p-value: p=0.99
The Maze procedure provides acceptable mid-term freedom from atrial fibrillation in patients without mitral valve disease, comparable to outcomes in patients with mitral valve disease.
No takes yet. Share an insight, caveat, or question.
May support Maze consideration in non-mitral valvular AF; extends mitral data but remains hypothesis-generating pending RCTs.
Iwamura et al. (2011) conducted a cohort in Atrial fibrillation (n=107). Maze procedure without mitral valve surgery vs. Maze procedure with mitral valve surgery was evaluated on Freedom from atrial fibrillation at 500 days (p=0.99). The Maze procedure in patients with non-mitral valvular atrial fibrillation achieved a 57% freedom from atrial fibrillation at 500 days, comparable to the 61% rate in patients with mitral valve disease.
