Key result
AF cryoablation with minimally invasive mitral valve repair achieved 71.4% sinus rhythm at 3.8 years, with better LA volume in SR vs AF relapse patients (60.6 vs 76.8 mL/mq; p=0.008).
Why the study?
The study was designed to explore, by thorough echocardiographic assessment, long-term morphological and functional left atrial outcomes after surgical AF cryoablation concomitant to minimally invasive mitral valve repair.
Does minimally invasive mitral valve repair with concomitant surgical AF cryoablation improve long-term morphological and functional left atrial outcomes in patients maintaining sinus rhythm?

May support concomitant cryoablation in mitral repair for SR; leaves open whether LA remodeling is causal or rhythm-mediated.

Does minimally invasive mitral valve repair with concomitant surgical AF cryoablation improve long-term morphological and functional left atrial outcomes in patients maintaining sinus rhythm?
p-value: p=0.008 and 0.015
Concomitant AF cryoablation during minimally invasive mitral valve repair provides high rates of sinus rhythm maintenance, which is associated with improved long-term left atrial morphology and function.
Anselmino et al. (2019) conducted a cohort in Atrial fibrillation and mitral valve disease (n=48). Minimally invasive mitral valve repair and concomitant surgical AF cryoablation was evaluated on Maximal LA volume indexed to body surface area and total LA emptying fraction (p=0.008 and 0.015). AF cryoablation with minimally invasive mitral valve repair achieved 71.4% sinus rhythm at 3.8 years, with better LA volume in SR vs AF relapse patients (60.6 vs 76.8 mL/mq; p=0.008).
