Abstract: Methods, systems, and computer readable media for utilizing a therapeutic ultrasound device to perform mitral valve decalcification are disclosed. One method includes acquiring, via an ultrasound imaging component, imaging data of a mitral valve in real-time, defining a therapeutic region of interest corresponding to the mitral valve, and utilizing, by a system controller engine, imaging data from the ultrasound imaging component to determine an interval period of minimal mitral annular movement. The method further includes defining a sequence of therapeutic targets within the region of interest of the mitral valve, utilizing the imaging data acquired in real-time by the ultrasound imaging component to provide a therapeutic ultrasound transducer array with a location and depth of an intra-annular focal zone within the mitral valve, and emitting a high intensity focused ultrasound (HIFU) pulse wave from the therapeutic ultrasound transducer array to each of the therapeutic targets of the mitral valve during the determined interval period and in accordance with the defined sequence.
