A heart in a heart: a case report of spontaneous flail of bicuspid aortic valve
Journal of Medical Case Reports, 2021 Background Aortic regurgitation is attributed to congenital and acquired abnormalities of the aortic valve or aortic valve supporting structures. The most common cause of aortic regurgitation is atherosclerotic degeneration of the valve, especially in ...

Bicuspid aortic valves undergo excessive strain during opening: A simulation study [PDF]
, 2013 ObjectiveThe objective of this study was to examine the influence of the morphologic characteristics of the bicuspid aortic valve on its disease progression by comparing the motion, stress/strain distribution, and blood flow of normal and stenotic ...

Bicuspid aortic valve disease [PDF]
Canadian Medical Association Journal, 2013 Bicuspid aortic valves are present in 1%–2% of the population, with men being 3 times more commonly affected than women. This disease is more than just anatomic variation and may be associated with other heart and aorta abnormalities as a result of molecular and connective tissue derangements.[1][

Including Aortic Valve Morphology in Computational Fluid Dynamics Simulations: Initial Findings and Application to Aortic Coarctation [PDF]
, 2012 Computational fluid dynamics (CFD) simulations quantifying thoracic aortic flow patterns have not included disturbances from the aortic valve (AoV). 80% of patients with aortic coarctation (CoA) have a bicuspid aortic valve (BAV) which may cause adverse ...

, 2011 Bicuspid aortic valve (BAV) disease is the most common congenital cardiovascular malformation with prevalence of 1-2% in the human population (Hoffman, 1990; Hoffman & Kaplan, 2002). Current clinical and scientific studies reveal that bicuspid aortic disease is not a simple valve condition.

Abnormal Haemodynamic Flow Patterns in Bicuspid Pulmonary Valve Disease
Frontiers in Physiology, 2017 Abnormal flow patterns in the aortas of those with bicuspid aortic valves (BAVs) are increasingly recognized as important in the pathogenesis of aortic dilatation but pulmonary flow patterns in bicuspid pulmonary valves have not been studied.

Biological niches within human calcified aortic valves. Towards understanding of the pathological biomineralization process [PDF]
, 2015 Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ...
