MRV (ml)	100 ± 25	85 ± 27	82 ± 23	< 0.0001	< 0.0001	< 0.0001	0.37
MRF (%)	55 ± 7	45 ± 9	50 ± 9	< 0.0001	< 0.0001	< 0.0001	0.08

Data are presented as the mean ± standard deviation (SD). The significance of the differences between the different methods is presented as P-values. CMR, cardiovascular magnetic resonance; MR, mitral regurgitation; MRF, mitral regurgitant fraction; MRV, mitral regurgitant volume
