Left Atrial Diameter is an Independent Predictor of Postoperative Atrial Fibrillation after Minimally Invasive Mitral Valve Surgery

Postoperative atrial fibrillation (POAF) is the commonest arrhythmia after cardiac surgery, associated with longer hospital stay, increased morbidity and mortality. Development of POAF is certainly multifactorial, however the exact mechanism remains unknown. Left atrial (LA) enlargement is commonly associated with mitral valve disease.
