Expert Consensus on Sizing and Positioning of SAPIEN 3/Ultra in Bicuspid Aortic Valves

Cardiology and Therapy, 2021
Severe aortic stenosis patients with bicuspid anatomy have been excluded from the major transcatheter aortic valve replacement (TAVI) randomized clinical trials. As a result, there is no official recommendation on bicuspid TAVI.

Bicuspid Aortic Valve [PDF]

, 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.

An Innovative “Tooth‐On‐Chip” Microfluidic Device Emulating the Structure and Physiology of the Dental Pulp Tissue

Advanced Healthcare Materials, EarlyView.
This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating

Diagnostic role of aortic valve calcium scoring in various etiologies of aortic stenosis

Scientific Reports, 2023
Most of the studies about aortic valve calcium (AVC) score in aortic stenosis (AS) were based on degenerative or bicuspid AS but not rheumatic AS. We aimed to study the diagnostic accuracy of AVC score to determine severe AS in various etiologies.

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.

Computational Analysis of Wall Shear Stress Patterns on Calcified and Bicuspid Aortic Valves: Focus on Radial and Coaptation Patterns

Fluids, 2021
Calcification and bicuspid valve formation are important aortic valve disorders that disturb the hemodynamics and the valve function. The detailed analysis of aortic valve hemodynamics would lead to a better understanding of the disease’s etiology.

Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

Advanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a

Role of three-dimensional transesophageal echocardiography in transcatheter aortic valve implantation of bicuspid aortic valve stenosis: A controlled study and comparison with tricuspid aortic valve stenosis

Cardiology Plus, 2018
Aims: This study aims to investigate the application of three-dimensional transesophageal echocardiography in aortic valve stenosis for the assessment of aortic valve ring size, to monitor the procedure of transcatheter aortic valve implantation (TAVI ...
