Data is presented as mean ± SD. For correlation between the methods, Pearson’s correlation coefficients were used. Significant correlation is present when: **: p < .01, ***: p < 0.001. CMR Cardiac magnetic resonance, RVEF Right ventricular ejection fraction derived from CMR, AVPDlat Lateral atrio-ventricular plane displacement, S’ S’-wave velocity, FAC Fractional area change, FWS Right ventricular free wall strain, TAPSE Tricuspid annular plane systolic excursion
