Unicuspid Aortic Stenosis in a Patient with Turner Syndrome: A Case Report

Frontiers in Cardiovascular Medicine, 2014
Congenital aortic valve anomalies are the cause of premature aortic stenosis in pediatric and younger adult populations. Despite being very rare, unicuspid aortic valves account for approximately 5% of isolated aortic valve replacements.

ProtoASNet: Dynamic Prototypes for Inherently Interpretable and Uncertainty-Aware Aortic Stenosis Classification in Echocardiography [PDF]

arXiv, 2023
Aortic stenosis (AS) is a common heart valve disease that requires accurate and timely diagnosis for appropriate treatment. Most current automatic AS severity detection methods rely on black-box models with a low level of trustworthiness, which hinders clinical adoption. To address this issue, we propose ProtoASNet, a prototypical network that directly

Bicuspid stenotic aortic valves: clinical characteristics and morphological assessment using MRI and echocardiography [PDF]

, 2011
Background Bicuspid aortic valve (BAV) is one of the most common congenital heart defects with a population prevalence of 0.5% to 1.3%. Identifying patients with BAV is clinically relevant because BAV is associated with aortic stenosis, endocarditis and ...

Fatty acids and aortic valve stenosis

Kardiologia Polska, 2021
Aortic valve stenosis (AVS), a valvulopathy that threatens life quality and longevity, in particular in an aging population. Yet no medical treatment is to date available emphasizing the need for more mechanistic insight into the disease to provide future treatment targets.

Potential Causality and Emerging Medical Therapies for Lipoprotein(a) and Its Associated Oxidized Phospholipids in Calcific Aortic Valve Stenosis.

Circulation Research, 2019
The prevalence of calcific aortic valve disease is increasing with aging of the population. Current treatment options for advanced or symptomatic aortic stenosis are limited to traditional surgical or percutaneous aortic valve replacement.

Detecting Heart Disease from Multi-View Ultrasound Images via Supervised Attention Multiple Instance Learning [PDF]

MLHC 2023, 2023
Aortic stenosis (AS) is a degenerative valve condition that causes substantial morbidity and mortality. This condition is under-diagnosed and under-treated. In clinical practice, AS is diagnosed with expert review of transthoracic echocardiography, which produces dozens of ultrasound images of the heart.
