Physics‐Informed Emulation of Systemic Circulation for Fast Parameter Estimation and Uncertainty Quantification

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 2, February 2026.
This work presents an innovative approach to modelling 1D fluid dynamics in complex networks using physics‐informed neural networks as surrogate models. By integrating physics‐based constraints with data‐driven learning, we develop an efficient and generalisable framework for uncertainty quantification and parameter estimation in real‐world ...

Segmental MRI pituitary and hypothalamus volumes post Fontan: An analysis of the Australian and New Zealand Fontan registry

International Journal of Cardiology Congenital Heart Disease
Objective: Short stature, central hypothyroidism and infertility are common in those with a Fontan circulation. Given that the Fontan circulation often results in hepatic portal venous congestion, we hypothesize that the hypothalamic-pituitary portal ...

Methylated Arginine Metabolites as Biomarkers for Clinical Status and Response to Type 5 Phosphodiesterase Inhibition in Patients With Fontan Circulation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background There is significant interest in NO pathway modulators, specifically type 5 phosphodiesterase inhibitors (PDE5is), to treat patients with a Fontan circulation. Trials, however, have had mixed results.

Hemodynamic assessment in transcatheter fenestration closure in patients after Fontan operation [PDF]

Българска кардиология
The fenestration in Fontan operation consists in creation of a communication between venous circulation and the pulmonary venous atrium, allowing direct passage of blood from the venous to the systemic circulation (right-to-left shunt).

The Fontan pathway: What′s down the road?

Annals of Pediatric Cardiology, 2008
The Fontan circulation results from routing of the systemic venous blood to the pulmonary circulation without a hydraulic source of a ventricle. Although a hypertrophied right atrium was thought to be essential for this circulation, the current form of ...

Ventricular Morphology and Outcomes in Fontan Circulation without Hypoplastic Left Heart Syndrome: A Single-Center's Experience

Reviews in Cardiovascular Medicine
Background: The impact of dominant ventricular morphology on Fontan patient outcomes remain controversial. This study evaluates long-term results of right ventricle (RV) dominance versus left ventricle (LV) dominance in Fontan circulation without ...

Validating the Concept of Mechanical Circulatory Support with a Rotary Blood Pump in the Inferior Vena Cava in an Ovine Fontan Model

Bioengineering
Right-sided mechanical support of the Fontan circulation by existing devices has been compounded by the cross-sectional design of vena cava anastomosis to both pulmonary arteries. Our purpose was to investigate whether increasing inferior vena cava (IVC)
