Background The hemodynamic profile and remodeling patterns of paradoxical low‐flow, low‐gradient aortic stenosis are well understood. However, some patients with severe aortic stenosis exhibit eccentric remodeling with enlarged left ventricular cavities,

Understanding extracellular vesicles in antiaging
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Deep Learning‐Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐

Inconsistency of Hemodynamic Data in Low-Gradient Severe Aortic Stenosis
The recently published meta-analysis by Dayan et al. [(1)][1] in the Journal evaluated the outcome and survival impact of aortic valve replacement in patients with low-gradient severe aortic stenosis (AS) in patients with preserved left ventricular ejection fraction, including paradoxical low ...

Neutrophil Extracellular Traps in Atherosclerosis and Cardiovascular Disease
NETs as integrated effectors in the atherosclerotic cardiovascular disease continuum. Activated neutrophils release NETs that promote endothelial injury, thrombo‐inflammation, and plaque destabilization throughout atherosclerotic disease progression. Created with BioRender.com.

Fourier Shell Analysis: k‐Space‐Based Metrics for Assessing Super‐Resolution in 4D Flow MRI
ABSTRACT Purpose To support the emerging field of super‐resolution (SR) in 4D flow MRI by proposing Fourier shell analysis to disentangle resolution enhancement from denoising effects during evaluation. Methods A thoracic aortic 4D flow MRI dataset was synthesized with various degrees of stenosis, providing ground truth flow fields generated using ...

Mitochondrial fission‐fusion imbalance contributes to age‐related cardio‐cerebral diseases like Alzheimer's disease, Parkinson's disease, Cerebral Infarction, Arteriosclerosis, Myocardial Infarction, Cardiac valve disease, Hypertension, and Cardiomyopathy. This review summarizes its regulatory mechanisms and interventions.
