  • Publication number: 20240242847
    Abstract: A predictive model for classification of tissue rupture risk is generated by providing a computer aided design (CAD) model suitable for simulating a balloon expandable transcatheter heart valve, and computing stress, strain, and/or displacement at the tissue as a function of expansion of the expandable transcatheter heart valve. The computed stress, strain, and/or displacement at the tissue enables determination of low, moderate or high tissue rupture risk as a function of the expansion at time of the expandable transcatheter heart valve deployment into a patient.

  • Publication number: 20240225740
    Abstract: A model of an in vivo heart valve device implanted in a patient is generated by providing a known model of a pre-implantation heart valve device, performing an imaging scan on the patient having an implanted heart valve device to obtain at least one patient specific landmark, deforming the known model to fit the at least one patient specific landmark to obtain a constructed patient-specific valve model, and simulating a valve leaflet and skirt for the constructed patient-specific valve model by finite element analysis. The constructed patient-specific valve model accurately represents geometries of the implanted heart valve device in its current in vivo form with an error less than 0.5 mm.

  • Publication number: 20240225739
    Abstract: A heart valve model includes a parametric leaflet model representing geometries of a heart valve constructed based on at least one landmark point associated with the heart valve. The heart valve model includes a ray casted anatomical structure constructed based on an automatic aortic root reconstruction algorithm to extract a shape of an aorta. The heart valve also includes an additional anatomical structure, wherein the parametric leaflet model, the ray casted anatomical structure, and the additional anatomical structure are combined to obtain the heart valve model.
