Quadrivalvular Involvement in Rheumatic Heart Disease: A Rare Case Report
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2022 Four-valve involvement (mitral, aortic, tricuspid, and pulmonary) in rheumatic heart disease (RHD) is an exceedingly rare entity. We report the case of a 24-year-old male, a known case of RHD, who presented with dyspnea and presyncope for 2 months.

Quadriscupid aortic valve with concurrent aortic stenosis and insufficiency [PDF]
, 2016 We present the case of a 22-year-old man with a congenital mixed aortic valve dysfunction who underwent cardiac Magnetic Resonance Imaging (MRI) for the assessment of aortic valve morphology and function prior to valve replacement.

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.

Systolic aortic regurgitation [PDF]
European Journal of Echocardiography, 2007 Aortic regurgitation is normally a diastolic phenomenon. Echocardiographic images of systolic aortic regurgitation in a patient with atrial fibrillation and heart failure are presented, and haemodynamic interpretation is provided.

TAVI for Pure Native Aortic Regurgitation: Are We There Yet?
Interventional Cardiology: Reviews, Research, Resources, 2019 Treatment of degenerative aortic stenosis has been transformed by transcatheter aortic valve implantation (TAVI) over the past 10–15 years. The success of various technologies has led operators to attempt to broaden the indications, and many patients ...

Human tissue valves in aortic position: determinants of reoperation and valve regurgitation [PDF]
, 2001 BACKGROUND: Human tissue valves for aortic valve replacement have a limited durability that is influenced by interrelated determinants. Hierarchical linear modeling was used to analyze the relation between these determinants

Surgical management of aortic root disease in Marfan syndrome and other congenital disorders associated with aortic root aneurysms [PDF]
, 2014 Elective root replacement in Marfan syndrome has improved life expectancy in affected patients. Three forms of surgery are now available: total root replacement (TRR) with a valved conduit, valve sparing root replacement (VSRR) and personalised external ...

Non-invasive hemodynamic analysis for aortic regurgitation using computational fluid dynamics and deep learning [PDF]
arXiv, 2021 Changes in cardiovascular hemodynamics are closely related to the development of aortic regurgitation, a type of valvular heart disease. Metrics derived from blood flows are used to indicate aortic regurgitation onset and evaluate its severity. These metrics can be non-invasively obtained using four-dimensional (4D) flow magnetic resonance imaging (MRI)

Reduced-order modeling of left ventricular flow subject to aortic valve regurgitation [PDF]
Physics of Fluids, 31(3), 031901 (2019), 2019 The present focus of heart flow studies is largely based on flow within the left ventricle and how this flow changes when subject to disease. However, despite recent advancements, a simple tractable model of even healthy left ventricular flow has not been produced and made available.
