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 (Journal article; Peer reviewed, 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 (Journal article; Peer reviewed, 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 (Journal article; Peer reviewed, 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 ... -
A novel case of impaired C-reactive protein response following open-heart surgery: A case report and review of the literature
Vinnes, Erik Wilhelm; Lillemoen, Paul Kjetil Soldal; Persson, Robert; Meyer, Klaus; Haaverstad, Rune; Monsen, Anne-Lise Bjørke (Journal article; Peer reviewed, 2021)Background C-reactive protein (CRP) is expected to increase in response to a range of inflammatory stimuli such as infections or extensive tissue trauma. Case report We present a novel case of severely impaired CRP ... -
Quantified planar collagen distribution in healthy and degenerative mitral valve: biomechanical and clinical implications
Sadeghinia, Mohammad Javad; Persson, Robert; Ellensen, Vegard Skalstad; Haaverstad, Rune; Holzapfel, Gerhard; Skallerud, Bjørn Helge; Prot, Victorien Emile; Urheim, Stig (Journal article; Peer reviewed, 2024)Degenerative mitral valve disease is a common valvular disease with two arguably distinct phenotypes: fibroelastic deficiency and Barlow’s disease. These phenotypes significantly alter the microstructures of the leaflets, ... -
The relationship between irritable bowel syndrome, functional dyspepsia, chronic fatigue and overactive bladder syndrome: A controlled study 6 years after acute gastrointestinal infection
Persson, Robert; Wensaas, Knut-Arne; Hanevik, Kurt; Eide, Geir Egil; Langeland, Nina; Rørtveit, Guri (Peer reviewed; Journal article, 2015-06-10)BACKGROUND: To investigate in a cohort with previous gastrointestinal infection and a control group the prevalence of overactive bladder syndrome (OAB), and how it was associated with three other functional disorders; ...
