May support cryomaze with mitral valve surgery in AF; leaves open need for RCTs to confirm benefit.
Observational (n=268)
What are the long-term survival and sinus rhythm restoration rates of cryomaze procedure concomitant with mitral valve surgery in patients with atrial fibrillation?
Cryomaze procedure concomitant with mitral valve surgery is an effective strategy for long-term restoration of sinus rhythm with excellent 10-year survival rates.
Funatsu et al. (2009) conducted an observational in Atrial fibrillation concomitant with mitral valve surgery (n=268). Cryomaze procedure was evaluated on 10-year cumulative survival rate. Cryoablation-based maze procedure concomitant with mitral valve surgery achieved a 91.8% rate of sinus rhythm restoration at discharge and a 10-year cumulative survival rate of 93.2%.
