Comparison of reduced models for blood flow using Runge-Kutta discontinuous Galerkin methods

, 2016
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 conserved quantities of mass and momentum, while another class describes mass ...

In vitro characterization of hemodynamics in bicuspid aortic valves: The impact of valve and ascending aortic morphologies

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 411-429, January 2026.
Abstract Purpose This study investigated the effect of bicuspid aortic valve (BAV) morphology and ascending aortic curvature (AAAc) bending angles on aortic hemodynamics, focusing on transvalvular jets and secondary helical flows that contribute to systolic hemodynamic stress linked to aortic complications.

Placental chorangiomas: Diagnostic challenges and contemporary approaches to fetal care

Pregnancy, Volume 2, Issue 1, January 2026.
Abstract Placental chorangiomas are the most common benign tumors of the placenta. Although most are small and asymptomatic lesions, giant chorangiomas are associated with an increased risk of adverse maternal and fetal outcomes. Therefore, in those affected by giant placental chorangioma, early diagnosis and intensive fetal monitoring are indicated to

Assessment Of Response To Heart Failure Therapy: Ventricular Volume Changes Versus Shape Changes [PDF]

, 2011
The prolate ellipsoid left ventricular geometry is crucial for its unique contraction and relaxation patterns. Perturbations in optimal cardiac function preceding overt heart failure ensue when this ellipsoid shape assumes a more spherical configuration.

Knowledge Gaps and Controversies on Cardiopulmonary Exercise Testing in the Assessment of Pulmonary Vascular Disease: An Official Statement of the Pulmonary Vascular Research Institute Exercise and Right Ventricular Function Task Force

Pulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT Exercise testing has long been essential for evaluating diagnosis, prognosis, and functional status in pulmonary hypertension (PH). Recent advances have clarified its role in defining reference values and prognostic markers. Nonetheless, substantial knowledge gaps persist regarding the implementation of invasive cardiopulmonary exercise ...

Ivabradine Preserves Cardiac Structure and Reduces Cell Death in Four Dogs With Preclinical Mitral Valve Disease

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Reduces cardiac remodelling and apoptosis in dogs with MMVD stage B2: Long‐term treatment with ivabradine in dogs with asymptomatic myxomatous mitral valve disease (MMVD) stage B2 reduced heart rate without impairing cardiac function. ABSTRACT Background Ivabradine, a specific funny channel blocker, has shown cardiovascular benefits in humans and ...
