Finite element analysis of mitral valve annuloplasty in Barlow's disease
Aguilera, Hans Martin; Urheim, Stig; Persson, Robert; Haaverstad, Rune; Skallerud, Bjørn Helge; Prot, Victorien Emile (Peer reviewed; Journal article, 2022)Barlow’s Disease affects the entire mitral valve apparatus causing mitral regurgitation. Standard annuloplasty procedures lead to an average of 55% annular area reduction of the end diastolic pre-operative annular area in ... -
In silico analysis provides insights for patient-specific annuloplasty in Barlow's disease
Aguilera, Hans Martin Dahl; Persson, Robert; Haaverstad, Rune; Skallerud, Bjørn Helge; Prot, Victorien Emile; Urheim, Stig (Peer reviewed; Journal article, 2023)Objective To predict the required mitral annular area reduction in patients with Barlow's disease to obtain a predefined leaflet area index by a novel in silico modeling method. Methods Three-dimensional echocardiography ... -
Mechanical behavior and collagen structure of degenerative mitral valve leaflets and a finite element model of primary mitral regurgitation
Sadeghinia, Mohammadjavad; Aguilera, Hans Martin Dahl; Urheim, Stig; Persson, Robert; Ellensen, Vegard Skalstad; Haaverstad, Rune; Holzapfel, Gerhard; Skallerud, Bjørn Helge; Prot, Victorien Emile (Peer reviewed; Journal article, 2023)Degenerative mitral valve disease is the main cause of primary mitral regurgitation with two phenotypes: fibroelastic deficiency (FED) often with localized myxomatous degeneration and diffuse myxomatous degeneration or ...
