Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]

arXiv, 2022
Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

Supravalvular aortic stenosis

The Journal of Thoracic and Cardiovascular Surgery, 1977
Enlargement of the aorta with a diamond-shaped patch of the noncoronary sinus of Valsalva may not be sufficient in severe cases of supravalvular aortic stenosis. This traditional reconstruction is asymmetric, and, if the fibrous supravalvular ring is thick and rigid, the aorta may not open wide with patch angioplasty, so that aortic obstruction may ...

Supravalvular aortic stenosis. Echocardiographic features. [PDF]

Heart, 1975
The echocardiographic manifestations of segmental supravalvular aortic stenosis are described in 2 patients. The diagnosis was confirmed by cardiac catheterization in both and at operation in 1. A systematic echocardiographic approach to such patients is described.

Application of Whole‐Exome Sequencing in the Prenatal Diagnosis of Foetuses With Central Nervous System Abnormalities

Molecular Genetics &Genomic Medicine, Volume 12, Issue 10, October 2024.
An additional 28.9% (43/149) diagnostic yield was increased by WES in the prenatal evaluation of foetuses with any CNS abnormalities anomaly following negative results by karyotyping and chromosome array. WES may also be of benefit for foetuses with isolated CNS anomalies.

Williams Syndrome and Neonatal Cardiac Surgery for Congenital Single Ventricle

JACC: Case Reports, 2020
Williams syndrome (WS) is an arteriopathic derangement associated with supravalvular aortic stenosis and branch pulmonary stenosis. We describe double-outlet right ventricle with mitral atresia and aortic arch hypoplasia in an infant with WS.

A rare case of discrete aortic coarctation in Williams-Beuren syndrome. Diagnostic and therapeutic considerations

La Pediatria Medica e Chirurgica, 2015
Williams-Beuren syndrome (WBS) is a genetic disorder caused by elastin gene deletions, and is characterized by cardiovascular malformations, primarily including supravalvular aortic stenosis and peripheral pulmonary stenosis.

A case series of rare pathologies of the aorta and the aortic arch in adolescents and younger adults: Transfer of experience for an individualized approach

Frontiers in Cardiovascular Medicine, 2022
ObjectiveWhile aneurysm of the aortic root, interrupted aortic arch, and aortic coarctation are the most frequent aortic diseases in adolescents and younger adults, there are a number of rare pathologies of the thoracic aorta that need individualized ...

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

Stenosis of the Branches of the Neopulmonary Artery after the Arterial Switch Operation: a Cardiac Magnetic Resonance Imaging Study [PDF]

, 2013
Background : The neonatal arterial switch operation (ASO) is now the standard of care for children born with transposition of the great arteries. Stenosis of the neopulmonary artery on long‑term follow up is a known complication.
