N-Acetylglucosamine (GlcNAc) is the major immunoepitope of group A streptococcal cell wall carbohydrates. Antistreptococcal antibodies cross-reactive with anti-GlcNAc and laminin are present in sera of patients with rheumatic fever. The cross-reactivity of these antibodies with human heart valvular
The aim of this study was to reveal the pathogenesis of aortic stenosis (AS) and regurgitation (AR) by comparing differences in mechanical and biochemical alterations. We applied scanning acoustic microscopy (SAM) to measure the speed of sound (SOS) through valves to estimate the elasticity and
Cardiovascular dysfunction appears to be an important complication of human immunodeficiency virus (HIV) infection and is being reported with greater frequency. There have been recent reports in the literature of HIV patients who suffer from vascular lesions such as large artery vasculopathy
OBJECTIVE
An association of aortic-valve stenosis and abnormal bleeding, particularly from gastrointestinal angiodysplasia, has been reported. In this setting, high-shear stress generated by the transvalvular gradient leads to a conformational change of plasmic von Willebrand factor, making this
