High recurrence of atrial fibrillation in patients with high tissue atrial natriuretic peptide and amyloid levels after concomitant maze and mitral valve surgery

A lower ANP atrial tissue expression and amyloid deposits were correlated with a high pre-operative hemodynamic loading, and those patients had a paradoxically lower AF recurrence after relief of the hemodynamic burden by concomitant maze and mitral valve surgery.
