Rare regulatory mutations disrupt mesenchymal molecular programs driving endocardial cushion formation in bicuspid aortic valve [PDF]

Nature Communications
Bicuspid aortic valve, a prevalent congenital malformation, predisposes individuals to severe complications. Although the condition exhibits substantial heritability, known protein-coding and common regulatory mutations explain a minority of cases.

Aortic annulus sizing in bicuspid and tricuspid aortic valves using CT in patients with surgical aortic valve replacement

Scientific Reports, 2021
The purpose of this study was to evaluate whether bicuspid anatomy affects the discrepancy between CT-derived annular size and intraoperative size. We retrospectively analyzed annular measurements in 667 patients who underwent surgical aortic valve ...

Infective endocarditis risk in patients with bicuspid aortic valve: Systematic review and meta-analysis

International Journal of Cardiology: Heart & Vasculature, 2023
Background: Antibiotic prophylaxis in bicuspid aortic valve patients is currently a matter of debate. Although it is no longer recommended by international guidelines, some studies indicate a high risk of infective endocarditis.

Bicuspid aortic valve associated with aortic thrombotic occlusion

The Egyptian Journal of Internal Medicine, 2016
The bicuspid aortic valve is associated with disorders of the aortic wall, including coarctation of the aorta and aortic dissection. The histologic abnormality underlying aortic complications in bicuspid aortic valve is cystic medial necrosis.
