Fabrication of a Stable, Low‐Cost, Patient‐Specific, Brain Phantom with Ventricles for Ultrasound Imaging

Advanced Engineering Materials, EarlyView.
Patient‐specific brain phantoms can replace animal trials, aid presurgical training, and enable in silico disease research on cerebrospinal fluid and ventricles. This study presents a method to create ventricular brain phantoms from three‐dimensional magnetic resonance images brain scans, resulting in durable, tunable, reproducible models that mimic ...

Effects of weight loss after sleeve gastrectomy on left ventricular myocardial work in obese patients

Frontiers in Cardiovascular Medicine
BackgroundObesity is a global epidemic and a major risk factor for cardiovascular diseases. Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric surgery, but its effect on cardiac functions remains unclear.

Soft Beats: A Dielectric Elastomer‐Based Ventricular Assist Device for Next‐Gen Heart Failure Management

Advanced Engineering Materials, EarlyView.
The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,

The association between left ventricular mass index and coronary collateral circulation in patients with chronic total occlusion

Türk Kardiyoloji Derneği Arşivi, 2019
Objective: Left ventricular (LV) hypertrophy predisposes the myocardium to ischemia through several mechanisms. The LV mass index (LVMI) is used as a readily available and reliable measurement of LV hypertrophy.

Impact of the left ventricular mass index on the outcomes of severe aortic stenosis. [PDF]

Heart, 2017
To elucidate the factors associated with high left ventricular mass index (LVMI) and to test the hypothesis that high LVMI is associated with worse outcome in severe aortic stenosis (AS).We analysed 3282 patients with LVMI data in a retrospective multicentre registry enrolling consecutive patients with severe AS in Japan.

Study of the correlation of epicardial adipose tissue with left ventricular mass and left ventricular mass index in patients with essential hypertension

International Journal of Research in Medical Sciences, 2020
Background: Epicardial Adipose Tissue (EAT) is recognized to be a cardiovascular risk factor. In addition to providing fuel to heart, it plays a pivotal role in the pathogenesis of atherosclerosis though the secretion of adipokines. This study aims to find the correlation of EAT with Left Ventricular Mass (LVM) and Left Ventricular Mass Index (LVMI) in

Precise Quantification of Angiogenesis in 3D Biomaterials Using in Vitro CAM Models: Enhancing 3Rs in Research and Minimizing in Vivo Dependency

Advanced Functional Materials, EarlyView.
The study develops elastin–fibrin scaffolds and evaluates angiogenesis using the chorioallantoic membrane (CAM) model. Advanced imaging with confocal microscopy and Indocyanine Green dye enables precise 3D quantification of vascular networks. Findings demonstrate superior microvessel visualization compared to micro‐CT using Microfil and Optiray 350 ...
