Successful percutaneous balloon dilatation of supravalvular aortic membrane

Heart Views, 2019
Supravalvular aortic stenosis is the least common type of left ventricular outflow tract obstruction. Primary balloon dilatation of membranous supravalvular aortic stenosis was performed in a 10-year-old male child with a remarkable reduction in systolic

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

An echocardiographic comparison of sutureless and conventional aortic valve replacement : a matched case-control study [PDF]

, 2018
Background: Patients at a high operative risk for conventional aortic valve replacement (AVR) may be offered sutureless valve implantation. Sutureless valves resemble conventional valves but incorporate an anchoring mechanism without using annular ...

Lipoprotein(a) in patients with aortic stenosis: Insights from cardiovascular magnetic resonance.

PLoS ONE, 2017
BackgroundAortic stenosis is the most common age-related valvular pathology. Patients with aortic stenosis and myocardial fibrosis have worse outcome but the underlying mechanism is unclear.

Myocardial extracellular volume quantification by computed tomography predicts outcomes in patients with severe aortic stenosis.

PLoS ONE, 2021
BackgroundThe extent of myocardial fibrosis in patients with severe aortic stenosis might have an important prognostic value. Non-invasive imaging to quantify myocardial fibrosis by measuring extracellular volume fraction might have an important clinical

Transcatheter Aortic Valve Implantation in Heart Failure Patients with Non-Severe Aortic Valve Stenosis

SciMedicine Journal, 2022
Introduction: aortic stenosis (AS) increases the afterload on the left ventricle, leading to structural changes in the heart muscle and gradual progression to heart failure (HF).

Lactate‐Activated GPR132‐Src Signal Induces Macrophage Senescence and Aggravates Atherosclerosis Under Diabetes

Advanced Science, EarlyView.
Elevated lactate in diabetes activates the GPR132‐Src pathway in macrophages, inducing macrophage senescence and further enhancing foam cell formation. This mechanism exacerbates atherosclerotic progression. Abstract Diabetes is widely acknowledged as a significant risk factor for atherosclerosis, facilitating plaque formation through various ...
