Computational fluid dynamics modelling of left valvular heart diseases during atrial fibrillation [PDF]
PeerJ, 4: e2240, 2016, 2016 Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics.

Different Sites of Vascular Access for Transcutaneous Aortic Valve Implantation (TAVI) [PDF]
, 2019 Aortic valve stenosis is a common valvular heart disease and its incidence is increasing day by day as the life expectancy is increasing gradually. It can be of congenital or acquired variety but in old ages aortic stenosis is acquired mostly and main ...

Genetic testing for aortic valve stenosis [PDF]
The EuroBiotech Journal, 2018 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.

European Heart Journal, 2019 Aims Clonal haematopoiesis of indeterminate potential (CHIP), defined as the presence of an expanded somatic blood cell clone without other haematological abnormalities, was recently shown to increase with age and is associated with coronary artery ...

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.

Automatic Aortic Valve Pathology Detection from 3-Chamber Cine MRI with Spatio-Temporal Attention Maps [PDF]
arXiv, 2023 The assessment of aortic valve pathology using magnetic resonance imaging (MRI) typically relies on blood velocity estimates acquired using phase contrast (PC) MRI. However, abnormalities in blood flow through the aortic valve often manifest by the dephasing of blood signal in gated balanced steady-state free precession (bSSFP) scans (Cine MRI).

On the role of aortic valve architecture for physiological haemodynamics and valve replacement. Part II: spectral analysis and anisotropy [PDF]
, 2023 Severe aortic valve stenosis can lead to heart failure and aortic valve replacement (AVR) is the primary treatment. However, increasing prevalence of aortic stenosis cases reveal limitations in current replacement options, necessitating improved ...

Annals of Pediatric Cardiology, 2021 A 3-month-old female was diagnosed at 1 month of age with DeSanto-Shinawi syndrome (DSS) and bicuspid aortic valve with trivial stenosis. The aortic valve stenosis progressed to severe within 2 months and required balloon aortic valvuloplasty.

Annals of Pediatric Cardiology, 2013 Stenosis of systemic semilunar valve in cyanotic congenital heart defects is rare. It can happen in truncus arteriosus with truncal valve stenosis and the very rare anomaly of tetralogy of fallot with aortic valve stenosis.
