Effect of Right Ventricular Outflow Tract Material Properties on Simulated Transcatheter Pulmonary Placement
Jalaj Maheshwari, Wensi Wu, Christopher N. Zelonis +9
Finite element (FE) simulations emulating transcatheter pulmonary valve (TPV) system deployment in patient-specific right ventricular outflow tracts (RVOT) assume material properti…
Simulation of Repair on Dynamic Patient-Specific Left Atrioventricular Valve Models
Stephen Ching, Christopher Zelonis, Christian Herz +12
Purpose: To develop and evaluate a dynamic, image-derived patient-specific physical simulation platform for the assessment of left atrioventricular valve (LAVV) repair strategies i…
Simulation of Transcatheter Therapies for Atrioventricular Valve Regurgitation in an Open-Source Finite Element Simulation Framework
Seda Aslan, Nicolas R. Mangine, Devin W. Laurence +8
Purpose: Transcatheter edge-to-edge repair (TEER) and annuloplasty devices are increasingly used to treat mitral valve regurgitation, yet their mechanical effects and interactions…
Geodesic-based Predictive Shape Modeling of the Right Ventricle in Patients with Hypoplastic Left Heart Syndrome
Ye Han, James Fishbaugh, Jared Vicory +9
Hypoplastic left heart syndrome (HLHS) is characterized by severe underdevelopment of left ventricle requiring staged surgical reconstruction (stages) to allow the right ventricle…
Effect of Parametric Variation of Chordae Tendineae Structure on Simulated Atrioventricular Valve Closure
Nicolas R. Mangine, Devin W. Laurence, Patricia M. Sabin +9
Many approaches have been used to model chordae tendineae geometries in finite element simulations of atrioventricular heart valves. Unfortunately, current "functional" chordae ten…
FEBio FINESSE: An open-source finite element simulation approach to estimate in vivo heart valve strains using shape enforcement
Devin W. Laurence, Patricia M. Sabin, Analise M. Sulentic +4
Finite element simulations are an enticing tool to evaluate heart valve function in healthy and diseased patients; however, patient-specific simulations derived from 3D echocardiog…
