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

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 ...

Significance and Usefulness of High‐Resolution 24‐h Electrocardiographic Parameters in Patients With Coronavirus Disease 2019 After Admission: A Prospective Cohort Study

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
In patients with coronavirus disease 2019 (COVID‐19) without an obvious cardiac disease, ambulatory electrocardiographic markers can be useful in assessing the risk of severe disease. Particularly, simultaneous positivity of late potential (LP) and T wave alternans (TWA) in patients with COVID‐19 was a poorer prognostic factor than LP or TWA alone ...

Short‐Term, Cycle‐Synchronized Adjunctive Therapy With Crocus Total Glucosides Tablets for Cardiac Protection Against Cancer Therapy‐Related Cardiac Dysfunction in Breast Cancer Patients: A Randomized, Double‐Blind, Placebo‐Controlled Trial

MedComm, Volume 7, Issue 6, June 2026.
Cycle‐synchronized CTGT therapy attenuates LVGLS decline and reduces CTRCD in breast cancer patients. This randomized, double‐blind, placebo‐controlled trial assessed whether cycle‐synchronized CTGT prevent CTRCD in 120 breast cancer patients receiving chemotherapy.

Comparison of Body Surface Area and Optimized Multivariate Allometric Model Approaches in Correcting Echocardiographic Aortic Dimensions for Physiological Variances: An International and Multicenter Study (CITED I)

MedComm, Volume 7, Issue 6, June 2026.
Ao‐a, Ao‐s, and Ao‐asc were measured by echocardiography in 1820 gender‐ and age‐matched Chinese and Italian healthy adults. Correction equations based on an optimized multivariate allometric model (OMAM) and BSA approaches were constructed in group A and tested in group B at a ratio of 7:3.

Coronary Blood Flow Dynamics During Continuous Flow Left Ventricular Assist Device Support: Insights From a Virtual Cohort and In‐Silico Simulations

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
A virtual HeartMate 3 patient cohort was generated to analyze how cardiac, coronary, and regulatory parameters influence left and right coronary blood flow using an in‐silico experimentation framework. Results showed left coronary flow is mainly shaped by regulatory mechanisms, whereas right coronary flow depends strongly on CF‐LVAD speed, ventricular ...

Sinogram‐based flow estimation in computed tomography using a physics‐informed neural network: Impact of gantry rotation speed, X‐ray fluence and pulsed acquisition on accuracy

Medical Physics, Volume 53, Issue 6, June 2026.
Abstract Background Non‐invasive imaging‐based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely‐used imaging modality that can robustly evaluate cardiovascular anatomy and function, but direct methods to estimate blood flow velocity from movies of contrast dynamics have not ...

Fetal Instability and Resuscitative Management During Fetal Intervention: A Retrospective, Descriptive Analysis of 245 Fetal Cardiac and Spina Bifida Procedures

Prenatal Diagnosis, Volume 46, Issue 7, Page 1104-1111, June 2026.
ABSTRACT Objective The heterogeneity of fetal surgery has led to variability in the nature and frequency of fetal instability. Understanding these differences is critical for optimizing management. Methods We reviewed all fetal atrial septal interventions (FASI) and fetoscopic myelomeningocele (fMMC) repairs with fetal instability performed at our ...
