the mitral and aortic valve data is scaled using the scaling ratios calculated from the LV reconstruction process (Fig. \[valve\_scaling\]-a). Then, the segmented mitral leaflets from LA Apical two-chambered and three-chambered view are fitted to the mitral orifice that is extracted from the SA basal section. For positioning the data, the three-chambered view planar data for the valves as well as the LV is matched to obtain the transverse location of the valve’s location. For the longitudinal positioning of the valves, the bases of the valve orifices have been assumed to be $5~mm$ above the LV base section at all time instances (based on the measurements from the LA sections). For the reconstruction of the aortic valve, only one sectional data is available i.e. from the Apical three-chambered view (Fig. \[valve\_scaling\]-a).

In order to reconstruct the mitral valve, a predictor-corrector type of algorithm has been used in this work as follows. The SA sections of the mitral valve are predicted using the LA leaflet data using curve fitting, and after the predictor step, the correction is computed and implemented. Correction at all the LA sections is computed and applied to all the predicted SA sections to have the corrected SA
