An in-silico analysis of experimental designs to study ventricular function: A focus on the right ventricle
PLOS Computational Biology.
Ed(s): A. Marsden
MeSH headings : Heart Ventricles; Humans; Hypertension, Pulmonary; Likelihood Functions; Research Design; Ventricular Dysfunction, Right; Ventricular Function
TL;DR:
A practical identifiability analysis of a multiscale cardiovascular model across four simulated experimental designs shows that model calibration to only RV pressure suffers from practical identIfiability issues and suffers from large forecast uncertainty in output space, but is substantially reduced once additional left ventricular pressure and volume data is included.

Sensitivity analysis and uncertainty quantification of 1-D models of pulmonary hemodynamics in mice under control and hypertensive conditions
INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING, 37(11).
author keywords: computational fluid dynamics; network models; pulmonary hypertension; sensitivity analysis; uncertainty quantification
MeSH headings : Animals; Bayes Theorem; Hemodynamics; Mice; Pulmonary Artery; Uncertainty; X-Ray Microtomography
TL;DR:
Results show that MPA pressure predictions are most sensitive to distal vascular resistance and that parameter influence changes with increasing network complexity, and suggest that PH leads to increased vascular stiffness and decreased peripheral compliance, congruent with clinical observations.

Assessing model mismatch and model selection in a Bayesian uncertainty quantification analysis of a fluid-dynamics model of pulmonary blood circulation
Journal of The Royal Society Interface, 17(173), 20200886.
author keywords: uncertainty quantification; model mismatch; model selection; MCMC; Gaussian processes; pulmonary circulation
MeSH headings : Animals; Bayes Theorem; Mice; Nonlinear Dynamics; Pulmonary Circulation; Uncertainty; X-Ray Microtomography
TL;DR:
Bayesian inference is used to quantify the uncertainty of model parameters and haemodynamic predictions in a one-dimensional pulmonary circulation model based on an integration of mouse haemodynamics and micro-computed tomography imaging data and shows that the nonlinear pressure–area relationship with stiffness dependent on the unstressed radius predicts best the data measured in a control mouse.
