    Assessment of Atrioventricular Valve Regurgitation Using Biomechanical Cardiac Modeling

    In this work we introduce the modeling of atrioventricular valve regurgitation in a spatially reduced order biomechanical heart model. The model can be fast calibrated using non-invasive data of cardiac magnet...

    Patient-Specific Biomechanical Modeling of Cardiac Amyloidosis – A Case Study

    We present a patient-specific biomechanical modeling framework and an initial case study for investigating cardiac amyloidosis (CA). Our patient-specific heartbeat simulations are in good agreement with the da...

    Sequential State Estimation for Electrophysiology Models with Front Level-Set Data Using Topological Gradient Derivations

    We propose a new sequential estimation method for making an electrophysiology model patient-specific, with data in the form of level sets of the electrical potential. Our method incorporates a novel correction...

    Constitutive Parameter Estimation Methodology Using Tagged-MRI Data

    We propose a methodology for performing the estimation of a key constitutive parameter in a biomechanical heart model – namely, the tissue contractility – using tagged-MRI data. We adopt a sequential data assi...

    Simulation of 3D Ultrasound with a Realistic Electro-mechanical Model of the Heart

    This paper presents a first set of experiments to integrate a realistic electro-mechanical model of a beating heart into simulated real-time three-dimensional (RT3D) ultrasound data. A novel ultrasound simulat...

    Cardiac Function Estimation from MRI Using a Heart Model and Data Assimilation: Advances and Difficulties

    In this article, we present a framework to estimate local myocardium contractility using clinical MRI, a heart model and data assimilation. First, we build a generic anatomical model of the ventricles includin...

    Towards Model-Based Estimation of the Cardiac Electro-Mechanical Activity from ECG Signals and Ultrasound Images

    We present a 3D numerical representation of the heart which couples the electrical and biomechanical models. To achieve this, the FitzHugh-Nagumo equations are solved along with a constitutive law based on the...
