Does a left-sided Cryomaze procedure restore sinus rhythm in patients with atrial fibrillation undergoing mitral valve surgery?
A left-sided Cryomaze procedure performed during mitral valve surgery effectively restores sinus rhythm, with success rates increasing over the first year but dependent on preoperative factors like left atrial size.
Rahmanian et al. (2008) conducted a cohort in Atrial fibrillation (n=141). Left-sided Cryomaze procedure was evaluated on Freedom from atrial fibrillation at mean follow-up. A left-sided Cryomaze procedure during mitral valve surgery achieved 87% freedom from atrial fibrillation at a mean follow-up of 305 days.
