Abstract: The invention relates to determining a model of a cardiac implant deployed in a cardiac region of a patient. A database including a plurality of different records is provided, each record including at least data representative of an image of a cardiac region and an associated model of the cardiac implant deployed in said cardiac region. A patient-specific image of the cardiac region for which the model of the cardiac implant deployed in said cardiac region is to be determined, is received. An approximation of the patient-specific image of the cardiac region is calculated based on a weighted combination of images of the cardiac region in a plurality of records. The model of the cardiac implant deployed in the cardiac region associated to the patient-specific image of said cardiac region is determined based on weighted combination of models of the cardiac implant associated to the images of the cardiac region in the plurality of records used for approximating said patient-specific image of the cardiac region.

Abstract: A system and method for selecting, from a series of cardiac implants having different sizes, the cardiac implant having optimum size for implantation in a patient. The method includes obtaining data representative of a patient-specific cardiac region and predicting the optimum size of the cardiac implant best matching a predefined criterion when deployed in the cardiac region. The predicting includes querying a database; determining parameter values for a parametric model representation of the patient-specific cardiac region; and/or entering the data representative of the patient-specific cardiac region into an artificial intelligence device.

Abstract: A system and method for evaluating a cardiac region of a subject from medical data. The method comprises obtaining, by the computer system, for a sequence of positions along a centerline of the coronary artery a sequence of associated luminal dimensions. The method comprises determining, by the computer system, data relating to a Fractional Flow Reserve, FFR, of the coronary artery by comparing the sequence of luminal dimensions of the coronary artery of the subject with one or more reference sequences of luminal dimensions. The method further comprises displaying the data relating to the FFR on a display.

Abstract: Systems and methods for fully automated anatomical analysis of an anatomical structure are provided to facilitate pre-operative planning. The computerized method may include obtaining a plurality of images, e.g., MSCT images, of patient-specific cardiovascular anatomy, and analyzing the MSCT images with a trained artificial intelligence module to identify one or more anatomical landmarks and to construct a virtual three-dimensional model of the anatomical structure. For example, the trained artificial intelligence module may execute segmentation, point detection, curve detection, or plane detection deep learning modules, independently or in combination, to identify the anatomical landmarks. The method further may include deriving anatomical measurements of the one or more identified anatomical landmarks, and displaying the virtual three-dimensional model alongside the anatomical measurements of the one or more identified anatomical landmarks.

Abstract: A method and system for patient-specific predicting of cyclic loading failure of a cardiac implant. The method includes providing an implant model representing a three dimensional mesh based representation of a cardiac implant, and providing a four-dimensional, 4D, patient-specific anatomical model representing a mesh based representation of a patient-specific cardiac region including a deployment site for the cardiac implant in a plurality of states corresponding to a plurality of moments in the cardiac cycle. A computer calculates deformation of the implant model deployed at the deployment site when, or before, the 4D patient-specific anatomical model transforms consecutively through the plurality of states, and the computer determines a risk of cyclic loading failure of the cardiac implant on the basis of the calculated implant deformation.
