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

A New Semi-supervised Learning Benchmark for Classifying View and Diagnosing Aortic Stenosis from Echocardiograms [PDF]
arXiv, 2021 Semi-supervised image classification has shown substantial progress in learning from limited labeled data, but recent advances remain largely untested for clinical applications. Motivated by the urgent need to improve timely diagnosis of life-threatening heart conditions, especially aortic stenosis, we develop a benchmark dataset to assess semi ...

Staging classification of aortic stenosis based on the extent of cardiac damage
European Heart Journal, 2017 Aims In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities.

Myocardial Scar and Mortality in Severe Aortic Stenosis
Circulation, 2018 Background: Aortic valve replacement (AVR) for aortic stenosis is timed primarily on the development of symptoms, but late surgery can result in irreversible myocardial dysfunction and additional risk.

Outcomes of Patients With Asymptomatic Aortic Stenosis Followed Up in Heart Valve Clinics
JAMA cardiology, 2018 Importance The natural history and the management of patients with asymptomatic aortic stenosis (AS) have not been fully examined in the current era. Objective To determine the clinical outcomes of patients with asymptomatic AS using data from the Heart ...

Plasma lipids and risk of aortic valve stenosis: a Mendelian randomization study
European Heart Journal, 2020 Aims Aortic valve stenosis is commonly considered a degenerative disorder with no recommended preventive intervention, with only valve replacement surgery or catheter intervention as treatment options.

A new technological system to revolutionize the management of valvular heart diseases: transcatheter aortic valve for the treatment of aortic stenosis [PDF]
arXiv, 2019 The goal of this study is a technology analysis of a revolution for the management of valvular heart diseases given by new technological system based on transcatheter artificial aortic valve, a delivery catheter and a loading system for the treatment of aortic stenosis (a narrowing of the aortic valve because of calcium build up that restricts blood ...

European Heart Journal-Cardiovascular Imaging, 2017 Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and ...

Progression of Hypertrophy and Myocardial Fibrosis in Aortic Stenosis
Circulation Cardiovascular Imaging, 2018 Background: Aortic stenosis is accompanied by progressive left ventricular hypertrophy and fibrosis. We investigated the natural history of these processes in asymptomatic patients and their potential reversal post-aortic valve replacement (AVR). Methods:

Transcatheter Aortic Valve Replacement in Low-risk Patients With Bicuspid Aortic Valve Stenosis.
JAMA cardiology, 2020 Importance The outcomes of transcatheter aortic valve replacement (TAVR) in low-risk patients with bicuspid aortic valve stenosis have not been studied in a large scale, multicentered, prospective fashion.
