A One Dimensional (1D) Computational Fluid Dynamics Study of Fontan-Associated Liver Disease (FALD)
Yaqi Li, Justin D. Weigand, Charles Puelz +2
Fontan-Associated Liver Disease (FALD) is a disorder arising from hemodynamic changes and venous congestion in the liver. This disease is prominent in patients with hypoplastic lef…
Parameter selection and optimization of a computational network model of blood flow in single-ventricle patients
Alyssa M. Taylor-LaPole, L. Mihaela Paun, Dan Lior +3
Hypoplastic left heart syndrome (HLHS) is a congenital heart disease responsible for 23% of infant cardiac deaths each year. HLHS patients are born with an underdeveloped left hear…
Fluid-structure interaction simulations for the prediction of fractional flow reserve in pediatric patients with anomalous aortic origin of a coronary artery
Charles Puelz, Craig G. Rusin, Dan Lior +5
Computer simulations of blood flow in patients with anomalous aortic origin of a coronary artery (AAOCA) have the promise to provide insight into this complex disease. They provide…
Deformable Registration of MRA and 4D Flow Images to Facilitate Accurate Estimation of Flow Properties within Blood Vessels
Dan Lior, Craig G. Rusin, Justin Weigand +5
A method is presented for the registration of MRA and 4D Flow images, with the goal of calculating blood flow properties using both modalities simultaneously. In particular, the me…
Computational framework for the generation of one-dimensional vascular models accounting for uncertainty in networks extracted from medical images
Michelle A Bartolo, Alyssa M Taylor-LaPole, Darsh Gandhi +9
Patient-specific computational modeling is a popular, non-invasive method to answer medical questions. Medical images are used to extract geometric domains necessary to create thes…
Simulating Cardiac Fluid Dynamics in the Human Heart
Marshall Davey, Charles Puelz, Simone Rossi +7
Cardiac fluid dynamics fundamentally involves interactions between complex blood flows and the structural deformations of the muscular heart walls and the thin, flexible valve leaf…
A computational study of aortic reconstruction in single ventricle patients
Alyssa M. Taylor-LaPole, Mitchel J. Colebank, Justin D. Weigand +2
Patients with hypoplastic left heart syndrome (HLHS) are born with an underdeveloped left heart. They typically receive a sequence of surgeries that result in a single ventricle ph…
Optimal fenestration of the Fontan circulation
Zan Ahmad, Lynn H. Jin, Daniel J. Penny +3
In this paper, we develop a pulsatile compartmental model of the Fontan circulation and use it to explore the effects of a fenestration added to this physiology. A fenestration is…
Computer simulation of surgical interventions for the treatment of refractory pulmonary hypertension
Seong Woo Han, Charles Puelz, Craig G. Rusin +3
This paper describes computer models of three interventions used for treating refractory pulmonary hypertension (RPH). These procedures create either an atrial septal defect, a ven…
Models for plasma kinetics during simultaneous therapeutic plasma exchange and extracorporeal membrane oxygenation
Charles Puelz, Zach Danial, Jon Marinaro +3
This paper focuses on the derivation and simulation of mathematical models describing new plasma fraction in blood for patients undergoing simultaneous extracorporeal membrane oxyg…
A reduced model for solute transport in compliant blood vessels with arbitrary axial velocity profile
Rami Masri, Charles Puelz, Beatrice Riviere
We derive a reduced model of solute transport in blood based on the center manifold theory. The derivation is carried out on a convection diffusion equation with general axial and…
A physiological model of the inflammatory-thermal-pain-cardiovascular interactions during a pathogen challenge
Atanaska Dobreva, Renee Brady, Kamila Larripa +3
Uncontrolled, excessive production of pro-inflammatory mediators from immune cells and traumatized tissues can cause systemic inflammatory issues like sepsis, one of the ten leadin…
A sharp interface method for an immersed viscoelastic solid
Charles Puelz, Boyce E. Griffith
The immersed boundary-finite element method (IBFE) is an approach to describing the dynamics of an elastic structure immersed in an incompressible viscous fluid. In this formulatio…
A priori error estimates of Adams-Bashforth discontinuous Galerkin methods for scalar nonlinear conservation laws
Charles Puelz, Beatrice Riviere
In this paper we show theoretical convergence of a second-order Adams-Bashforth discontinuous Galerkin method for approximating smooth solutions to scalar nonlinear conservation la…
Comparison of reduced models for blood flow using Runge-Kutta discontinuous Galerkin methods
Charles Puelz, Suncica Canic, Beatrice Riviere +1
One-dimensional blood flow models take the general form of nonlinear hyperbolic systems but differ greatly in their formulation. One class of models considers the physically conser…
Numerical method of characteristics for one-dimensional blood flow
Sebastian Acosta, Charles Puelz, Beatrice Riviere +2
Mathematical modeling at the level of the full cardiovascular system requires the numerical approximation of solutions to a one-dimensional nonlinear hyperbolic system describing f…
