While 2D-iVFM uses three-chamber color Doppler images, 3D-iVFM is based on the clinical mode of triplane color Doppler echocardiography. As in the previous twodimensional version, 3D-iVFM relies on mass conservation and free-slip endocardial boundary conditions. For sake of robustness, the optimization problem was written as a constrained least-squares problem. We tested and validated 3D-iVFM in silico through a patient-specific heart-flow CFD (computational fluid dynamics) model, as well as in vivo in one healthy volunteer. The intraventricular vortex that forms during left ventricular filling was deciphered. After further validation, 3D-iVFM could offer clinically compatible 3-D echocardiographic insights into left intraventricular hemodynamics. %G English %2 https://cnrs.hal.science/hal-03538680/document %2 https://cnrs.hal.science/hal-03538680/file/Vixege2021a_hal.pdf %L hal-03538680 %U https://cnrs.hal.science/hal-03538680 %~ INSERM %~ UNIV-ST-ETIENNE %~ CNRS %~ UNIV-LYON1 %~ INSA-LYON %~ CARDIO %~ I3M_UMR5149 %~ CREATIS %~ IMAG-MONTPELLIER %~ MIPS %~ UNIV-MONTPELLIER %~ INSA-GROUPE %~ UDL %~ UNIV-LYON %~ UM-2015-2021
