in vivo measurements, i.e., FSI methods are considered valid when their motion is similar to prescribed ones. Therefore, it is desirable to use image-based geometry/motion if available. However, the main concern about using the medical images in CFD simulations is their accuracy in terms of spatio-temporal resolution.

Several imaging techniques are currently available for LV, e.g., computed tomography (CT) [@watabe2015enhancement; @szafer2019simplified], magnetic resonance imaging (MRI) [@lapa2015imaging], cardiac magnetic resonance (CMR) [@morris2018magnetic], and 3D-echo [@monaghan2006role]. However, most of these techniques are either very expensive or suffer from the lack of spatial or temporal resolution within an acceptable acquisition time. Among these, 2D-echo is the most widely used non-invasive imaging technique, due to its low costs and fast acquisition  [@chamsi2017handheld]. 2D echo can provide high temporal resolution (from 250 fps, down to 50 fps for resolving the whole LV) compared to other techniques [@rajan2016automated]. However, the acquired data from segmentation of 2D echo are only available on a few standard planes from which the 3D geometry need to be reconstructed [@rajan2016automated].

For CFD simulations of LV, the valves need to be modeled. Due to the highly dynamic motion and geometry of the leaflet valve, the reconstruction of heart valves still remains a
