An Open-Source Web-Based Viewer for Disseminating Image-Derived Models
Christian Herz, Kyle Sunderland, Matthew Daemer +11
Patient-specific 3-dimensional (3D) models are increasingly central to planning surgery and catheter-based intervention in children with congenital heart disease (CHD), whose anato…
SDFStent: Real-time interactive virtual stenting via SDF deformation fields
Bohan J. Li, Nicholas C. Dorn, Andras Lasso +4
Stenting is among the most common transcatheter interventions for congenital heart disease (CHD). Patient-specific computational fluid dynamics (CFD) simulations can predict hemody…
Effect of Right Ventricular Outflow Tract Material Properties on Simulated Transcatheter Pulmonary Placement
Jalaj Maheshwari, Wensi Wu, Christopher N. Zelonis +9
FE simulations emulating TPV system deployment in patient-specific right ventricular outflow tracts (RVOT) assume material properties for the RVOT and adjacent tissues. Sensitivity…
Integrated Open-Source Framework for Simulation of Transcatheter Pulmonary Valves in Native Right Ventricular Outflow Tracts
Christopher N. Zelonis, Jalaj Maheshwari, Wensi Wu +14
Pulmonary insufficiency is a consequence of transannular patch repair in Tetralogy of Fallot (ToF), leading to late morbidity and mortality. Transcatheter native outflow tract pulm…
SlicerNNInteractive: A 3D Slicer extension for nnInteractive
Coen de Vente, Kiran Vaidhya Venkadesh, Bram van Ginneken +1
SlicerNNInteractive integrates nnInteractive, a state-of-the-art promptable deep learning-based framework for 3D image segmentation, into the widely used 3D Slicer platform. Our ex…
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…
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…
