Simulation-Based Design of Bicuspidization of the Aortic Valve [PDF]
arXiv, 2023 Objective: Severe congenital aortic valve pathology in the growing patient remains a challenging clinical scenario. Bicuspidization of the diseased aortic valve has proven to be a promising repair technique with acceptable durability. However, most understanding of the procedure is empirical and retrospective.

Cardiovascular computed tomography for the detection of quadricuspid aortic valve: A case report
Radiology Case Reports, 2023 Aortic regurgitation (AR) represents a significant cause of morbidity and mortality. Due to its low cost and widespread availability, echocardiography remains the frontline for aortic valve (AV) assessment. However, poor sonographic windows may limit the

An incidental rare finding of the quadricuspid aortic valve [PDF]
, 2013 Kuadriküspid kapak, uniküspid ve biküspid aort kapağa göre hayli nadir görülen bir doğumsal malformasyondur. Genellikle izole doğumsal bir anomali şeklinde saptanması yanında bazen de diğer malformasyonlar ile ilişkili olabilmektedir. Kuadriküspid aort

A reduced 3D-0D FSI model of the aortic valve including leaflet curvature [PDF]
arXiv, 2021 We introduce an innovative lumped-parameter model of the aortic valve, designed to efficiently simulate the impact of valve dynamics on blood flow. Our reduced model includes the elastic effects associated with the leaflets' curvature and the stress exchanged with the blood flow.

Wall shear stress and pressure patterns in aortic stenosis patients with and without aortic dilation captured by high-performance image-based computational fluid dynamics [PDF]
arXiv, 2022 Spatial patterns of elevated wall shear stress and pressure due to blood flow past aortic stenosis (AS) are studied using GPU-accelerated patient-specific computational fluid dynamics. Three cases of moderate AS, one with a dilated ascending aorta and two within the normal range (root diameter less than 4cm) are simulated for physiological beat cycle ...

Management of severe aortic valve stenosis in the neonate [PDF]
, 2017 Aortic valve stenosis (AS) causing obstruction to the left ventricular outfl ow, and hence reduction of the cardiac output, remains a therapeutic challenge for paediatric cardiologists and cardiothoracic surgeons.

Aortic insufficiency in a patient with a quadricuspid aortic valve and abnormal left coronary ostium
Journal of the Practice of Cardiovascular Sciences, 2016 A 64-year-old female had symptomatic severe aortic insufficiency and was taken up for aortic valve replacement. The patient was found to have a quadricuspid aortic valve and abnormally located early bifurcated left coronary ostium which were very near to
