Background: Prior investigations suggest that superimposing continuous flow on aortic flow (continuous aortic flow augmentation) produces vasodilation, cardiac unloading, and improved cardiac performance.
Methods And Results: We compared percutaneous continuous aortic flow augmentation (flow
Conclusions: Continuous aortic flow augmentation improved cardiac performance, improving cardiac index and pulmonary capillary wedge pressure, but statistical significance for the primary efficacy end point was not attained. Hemodynamic and clinical observations provide direction toward additional studies to further investigate the clinical effects of this treatment.

Fluid-structure-growth modeling in ascending aortic aneurysm: capability to reproduce a patient case.

Predicting the evolution of ascending aortic aneurysm (AscAA) growth is a challenge, complicated by the intricate interplay of aortic geometry, tissue behavior, and blood flow dynamics. We investigate a flow-structural growth and remodeling (FSG) model based on the homogenized constrained mixture theory to simulate realistic AscAA growth evolution. Our approach involves initiating a finite element model with an initial elastin insult, driven by the distribution of Time-Averaged Wall Shear Stress (TAWSS) derived from computational fluid dynamics simulations.

Objectives: The aim of this study was to compare the adrenal gland size of fetuses with congenital heart diseases (CHD) and normal fetuses.
Methods: In this cross-sectional prospective study we measured the fetal adrenal gland size (total width, cortex width, medulla width, adrenal gland ratio of total width divided by medulla width) in 62 fetuses with CHD and 62 gestational-age-matched controls between 20 + 0 and 39 + 3 weeks of gestation. First, we clustered three CHD subgroups: CHD group_1 with a normal outflow tract (n=7), CHD group_2 with an altered outflow tract and anterograde flow in the ascending aorta (n=39) and CHD group_3 with an altered outflow tract and retrograde flow in the ascending aorta (n=16).
Resveratrol promotes cholesterol efflux from dendritic cells and controls costimulation and T-cell activation in high-fat and lipopolysaccharide-driven atherosclerotic mice.

Cholesterol aggregation in dendritic cells (DCs) triggers an inflammatory response and accelerates the development of atherosclerosis (AS). Resveratrol (RES), a natural compound with anti-inflammatory and cholesterol metabolism regulatory properties, has been shown to influence the maturation and inflammatory functions of DCs. However, its relationship with cholesterol metabolism remains unclear.

Background: During infant aortic arch reconstruction, traditional electroencephalography (EEG) provides only qualitative data limiting neuromonitoring efficacy. Interhemispheric differences in the alpha:delta ratio (ADR) and suppression ratio (SR) measured using quantitative EEG generate numerical trends that may suggest cerebral ischemia. We hypothesized that the ADR and SR during cardiopulmonary bypass (CPB) would correlate with hemodynamics, and that ADR and SR interhemispheric differences would precede neurological injury from infants requiring aortic arch reconstruction.

Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.
