MVnet: automated time-resolved tracking of the mitral valve plane in CMR long-axis cine images with residual neural networks: a multi-center, multi-vendor study

Table 3 Automated clinical metric accuracy of mitral valve derived parameters

Clinical agreement	n subjects	Manual measures	Automated measures	Error measures	ICC (CI 95%)
MAPSE (mm)	143	12.3 ± 4.0	12.1 ± 3.9	−0.2 ± 1.3	0.94 (0.92–0.96)
LV e’ (cm/s)	96	6.6 ± 4.1	6.6 ± 3.7	0.0 ± 1.5	0.93 (0.90–0.95)

The mean ± standard deviation are reported for manual and automated measures and their error, evaluated on the mixed test set with the proposed model (\({{\text{MVnet}}_{\text{Mixed}}}\)). MAPSE mitral annular plane systolic excursion, LV left ventricle, ICC intra-class correlation coefficient, CI confidence interval
