Geometric characteristics of bicuspid aortic valvesCentral MessagePerspective

JTCVS Techniques, 2021
Objective: We studied the coaptation angles α and β in bicuspid aortic valve geometry from computed tomography scan images. Methods: In 45 patients, we calculated the coaptation angle α (the angle between the nonfused commissures crossing the center of ...

Anatomy assessment of permanent mandibular premolar teeth in a selected Iranian population using cone-beam computed tomography

Dental Research Journal, 2021
Background: Appropriate cleaning and shaping and three-dimensional obturation of the root canal system lead to a successful endodontic treatment. To achieve this, complete knowledge of the internal anatomy of root canals is necessary.

Aortic valve morphology and paravalvular leak regression after a self-expandable transcatheter aortic valve replacement

Frontiers in Physiology, 2023
Aims: The study aimed to compare paravalvular leak (PVL) changes after a transcatheter aortic valve replacement (TAVR) with self-expandable prosthesis between different aortic valve morphologies and evaluate the impact of paravalvular leak regression on ...

Pathological Investigation of Congenital Bicuspid Aortic Valve Stenosis, Compared with Atherosclerotic Tricuspid Aortic Valve Stenosis and Congenital Bicuspid Aortic Valve Regurgitation [PDF]

, 2016
Congenital bicuspid aortic valve (CBAV) is the main cause of aortic stenosis (AS) in young adults. However, the histopathological features of AS in patients with CBAV have not been fully investigated.We examined specimens of aortic valve leaflets ...

Presence Of A Congenitally Bicuspid Aortic Valve Among Patients Having Combined Mitral And Aortic Valve Replacement [PDF]

, 2012
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent.

Fracture resistance of polyetheretherketone, Ni-Cr, and fiberglass postcore systems: An in vitro study

Dental Research Journal, 2022
Background: It is unclear which the material is a better choice for post and core rehabilitation systems in endodontically treated teeth. This study aimed to compare the fracture resistance of three different postcore systems.

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 ...

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][
