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 ...

Bicuspid aortic valve outcomes [PDF]

Cardiology in the Young, 2016
AbstractBackgroundBicuspid aortic valve is the most common CHD. Its association with early valvular dysfunction, endocarditis, thoracic aorta dilatation, and aortic dissection is well established.ObjectiveThe aim of this study was to assess the incidence and predictors of cardiac events in adults with bicuspid aortic valve.MethodsWe carried out a ...

Evaluation of effort zones between custom implant sinterized and the prefabricated implant though photoelasticity

Revista Facultad de Odontología Universidad de Antioquia, 2022
Introduction: the use of custom implants is a very common treatment; we assess and compare their behavior against that of conventional implants. This study aimed to make sure that the stress zones of the custom implant are different from those presented ...

Fracture resistance of five intra-orifice barriers in endodontically treated mandibular premolars: An in vitro study [PDF]

Vojnosanitetski Pregled
Background/Aim. Endodontically treated teeth (ETT) are more prone to fractures than vital teeth, and insertion of an intra-orifice barrier (IOB) can increase their fracture resistance (FR).
