    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...

    Trials on Tissue Contractility Estimation from Cardiac Cine MRI Using a Biomechanical Heart Model

    In this paper we apply specific data assimilation methods in order to estimate regional contractility parameters in a biomechanical heart model, using as measurements real Cine MR images obtained in an animal exp...

    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...
