European Journal of Cardio-Thoracic Surgery, 2019 OBJECTIVES: The bicuspid aortic valve (BAV) exists in a wide variety of valve phenotypes. The aim of this study was to assess the anatomical characteristics of the different phenotypes and develop a classification system to aid surgical repair. METHODS:

A new technological system to revolutionize the management of valvular heart diseases: transcatheter aortic valve for the treatment of aortic stenosis [PDF]
arXiv, 2019 The goal of this study is a technology analysis of a revolution for the management of valvular heart diseases given by new technological system based on transcatheter artificial aortic valve, a delivery catheter and a loading system for the treatment of aortic stenosis (a narrowing of the aortic valve because of calcium build up that restricts blood ...

Simulation-Based Design of Bicuspidization of the Aortic Valve [PDF]
arXiv, 2023 Objective: Severe congenital aortic valve pathology in the growing patient remains a challenging clinical scenario. Bicuspidization of the diseased aortic valve has proven to be a promising repair technique with acceptable durability. However, most understanding of the procedure is empirical and retrospective.

Circulation. Cardiovascular Interventions, 2019 Background: Sizing for transcatheter aortic valve implantation in bicuspid aortic valves (BAV) remains controversial. Methods and Results: The aim of the BAVARD (Bicuspid Aortic Valve Anatomy and Relationship With Devices) retrospective registry is to ...

Aortic cusp extension valvuloplasty with or without tricuspidization in children and adolescents: Long-term results and freedom from aortic valve replacement [PDF]
, 2010 ObjectiveAortic cusp extension valvuloplasty is increasingly used in the management of children and adolescents with aortic stenosis or regurgitation. The durability of this approach and the freedom from valve replacement are not well defined.

Cardiovascular Research, 2018 Aims Emerging evidence indicates that long non-coding RNAs (lncRNAs) play a vital role in cardiovascular physiology and pathology. Although the lncRNA TUG1 is implicated in atherosclerosis, its function in calcific aortic valve disease (CAVD) remains ...

A reduced 3D-0D FSI model of the aortic valve including leaflet curvature [PDF]
arXiv, 2021 We introduce an innovative lumped-parameter model of the aortic valve, designed to efficiently simulate the impact of valve dynamics on blood flow. Our reduced model includes the elastic effects associated with the leaflets' curvature and the stress exchanged with the blood flow.

Hemangioma of the Atherosclerotic Changed Aortic Valve
Case Reports in Cardiology, 2019 The incidence of heart valve hemangioma is very low and is mostly observed in the mitral and tricuspid valve. In 2006, two cases of aortic valve hemangioma were reported for the first time, including one with calcifying aortic valve stenosis.
