Abstract:
Aortic valve stenosis (AVS) is the most common valve disease in adults. Severe forms are associated with acquired von Willebrand syndrome (aVWS) with loss of the largest von Willebrand factor (VWF) multimers. Diagnostic gold standard is the VWF multimer analysis. Valve replacement rapidly restores the VWF structure. Uncertainty exists if this effect is permanent and how functional VWF assays perform compared with multimer analysis. We studied 21 consecutive patients with severe AVS before and 6 to 18 months after valve surgery and compared them with 14 controls without valve disease referred f

Abstract:
Abstract Aortic valve stenosis (AVS) is a congenital aortic defect in which the aortic lumen narrows due to thickening or calcification of the aortic valve without obstructing left ventricular outflow. Depending on the site of obstruction, AVS is classified as valvular, sub-valvular or supra-valvular. The prevalence of AVS is about 3% and increases with age. One in eight persons over the age of 75 years has moderate or severe AVS. AVS has autosomal dominant inheritance. It can be associated with mutations in the following genes: NOTCH1, SMAD6, SMAD4, and ELN. This Utility Gene Test was develop

Abstract:
SummaryThe mechanisms of the progression of aortic valve stenosis are unknown. The involvement of mononuclear cells and of chronic systemic inflammation has been suggested by analysis of pathological specimens. We hypothesize that shear stress caused by the constricted aortic orifice contributes to systemic proinflammation by activation of circulating blood cells and thereby generation of microparticles. Using flow cytometry we analyzed 22 patients with severe aortic valve stenosis (AVS) and 18 patient controls for the generation of circulating microparticles from platelet-(PMPs: CD31+/CD61+ o

Aortic valve stenosis (AVS) is an increasingly prevalent disease in our aging population.

ABSTRACTThe global impact of the spectrum of valve diseases is a crucial, fast‐growing, and underrecognized health problem. The most prevalent valve diseases, requiring surgical intervention, are represented by calcific and degenerative processes occurring in heart valves, in particular, aortic and mitral valve. Due to the increasing elderly population, these pathologies will gain weight in the global health burden. The two most common valve diseases are aortic valve stenosis (AVS) and mitral valve regurgitation (MR). AVS is the most commonly encountered valve disease nowadays and affects almo

Aortic valve stenosis (AVS) is the most prevalent valvular heart disease in the Western World with exponentially increased incidence with age. If left untreated, the yearly mortality rates increase up to 25%. Currently, no effective pharmacological interventions have been established to treat or prevent AVS. The only treatment modality so far is surgical or transcatheter aortic valve replacement (AVR). Lipoprotein(a) [Lp(a)] has been implicated as a pivotal player in the pathophysiology of calcification of the valves. Patients with elevated levels of Lp(a) have a higher risk of hospitalization

To date, CAVS is a slow, progressive, multifactorial disorder considered to be actively driven by several cellular and molecular processes.

Heart disease is the number one cause of death today with aortic valve stenosis (AVS) being a major contributor to the mortality rate1. Because of the invasive nature of Aortic Valve Resection (AVR), the typical treatment for AVS, between 30–60% of patients affected by severe aortic stenosis cannot be treated surgically, usually due to age and advanced comorbidities. Qualifying individuals must undergo extensive rehabilitation and of those who qualify 4.3% to 25% do not survive the first year following the procedure3,4.

Abstract:
Gorlin equation has been applied in clinical practice for evaluating the aortic valve area (AVA) of vascular and aortic valve stenosis for past sixty years [1]. It was derived using the Bernoulli equation across the stenosis with the assumption that the velocity of the fluid behind the stenosis is much greater than the velocity upstream of the stenosis. Because of this assumption, the calculated stenosed area may have large error if the flow rate across the valve is low or the stenosis is mild [2]. In a recent paper, Okpara and Agarwal [3] proposed a new equation (Agarwal – Okpara equation) wh

Abstract:
Abstract Aortic stenosis (AS) is one of the most common valvular heart diseases around the globe. The accurate assessment of AS severity is important and strongly associated with accurate interpretation of the hemodynamic parameters across the stenotic valve. In this study, we conducted in vitro fluid dynamic experiments to investigate the pulsatile flow characteristics of a stenotic aortic valve as a function of heart rate. An in vitro cardiovascular flow simulator was used to generate pulsatile flow with a prescribed waveform (40% systolic period and 4L/min cardiac output) under varied heart

Abstract:
Background: The Electrocardiogram (ECG) is a widely utilized, non-invasive, cost-effective cardiac test. Its integration with Artificial Intelligence (AI) has empowered it to become a potent screening tool and a predictor for various cardiovascular diseases, especially in asymptomatic individuals. Objective: This review investigates the utility of AI-powered ECG in early detection of cardiac conditions, focusing on conditions such as low ejection fraction (LEF), atrial fibrillation (AF), aortic valve stenosis (AVS), and cardiac amyloidosis (CA). Methods: A literature review spanning 2018 to 20
