An Integrated Lumped Parameter Model and Computational Fluid Dynamics Framework for Predicting Hemodynamic Parameters in Pulmonary Vein Stenosis

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This work presents a novel computational simulation framework for the study of pulmonary venous hemodynamics that integrates a closed‐loop lumped parameter model (LPM) of the cardiovascular system with a computational fluid dynamics (CFD) model of the pulmonary veins and left atrium. Coupling of the LPM and CFD models was accomplished through surrogate

Exploring the Mechanisms of Total Saponins of Black Ginseng and Ginsenoside Rg3 Against Doxorubicin‐Induced Cardiotoxicity

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
TSF and Rg3 demonstrate significant cardioprotective effects against DOX‐induced cardiotoxicity (DIC) by mitigating oxidative stress, inflammation, and apoptosis while preserving mitochondrial function. These findings provide novel insights into the clinical relevance of TSF and Rg3 in the management of DIC.

Retrospective Cross‐Sectional Study of Transthoracic Echocardiographic Reports in Patients Diagnosed With Aortic Regurgitation in Mashhad, Iran; to Evaluate Echocardiographic Determinants of AR Severity, With Specific Focus on STJ‐Related Parameters

Health Science Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Background and Aims Aortic regurgitation (AR) is associated with characteristic changes in aortic root geometry. Data on detailed echocardiographic patterns of AR in Iranian cohorts remain limited. This study aimed to describe the echocardiographic and etiologic characteristics of patients with AR and to assess the associations between ...

Utilization of ultrasonic aspirator for combined aortic and mitral valve decalcification: a case study

Journal of Cardiothoracic Surgery
Mitral and aortic annular calcification is an age-related degenerative process that can result in severe mitral and/or aortic stenosis and/or regurgitation.

Suspected Cardioembolic Stroke Linked to Left Atrial Stunning After Pulsed Field Ablation for Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
After pulsed field ablation with pulmonary vein and posterior wall isolation, a patient developed ischemic stroke due to left carotid artery occlusion. Pathology of the retrieved thrombus revealed an acute red thrombus, suggesting left atrial stunning–induced thrombus formation.

Mitral stenosis: etiology and mechanism of disease, physiological change, symptoms and diagnostic evaluation

Journal of Health Science and Medical Research (JHSMR), 2004
Valvular heart disease is a common health problem and affects the quality of life. The mitral valve is the most often diseased of all cardiac valves, particularly with its proclivity to rheumatic process involvement.

Feasibility and Safety of High‐Power Settings for Electrical Isolation of the Superior Vena Cava Using a Catheter Capable of Local Impedance and Contact Force Monitoring

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
High‐power superior vena cava isolation using a contact force– and local impedance–sensing catheter achieved safe and consistent first‐pass isolation. Local impedance decreased more rapidly than generator impedance, accurately reflecting effective lesion formation and enabling reliable real‐time assessment in thin SVC myocardium.
