  1. AF atrial fibrillation, AV atrioventricular, CV cardiovascular, MV mitral valve, MVI mitral valve insufficiency
  2. aORs were calculated by logistic regression and adjusted for age, pulmonary hypertension, prior AVR, LVEDD, LVESD, left/right atrium (mm), chordae elongation and log EuroScore. In the multivariate analysis only data of patients with available values for all variables taken into account for adjustment were included (n = 897). No BMI or mitral opening data were considered as there was a considerable degree of missing values
