• 3D Myocardial Mechanical Wave Measurements: Toward In Vivo 3D Myocardial Elasticity Mapping 

      Salles, Sebastien; Espeland, Torvald; Rodriguez-Molares, Alfonso; Aase, Svein Arne; Hammer, Tommy; Støylen, Asbjørn; Aakhus, Svend; Løvstakken, Lasse; Torp, Hans (Peer reviewed; Journal article, 2020)
      Objectives This study aimed to investigate the potential of a novel 3-dimensional (3D) mechanical wave velocity mapping technique, based on the natural mechanical waves produced by the heart itself, to approach a noninvasive ...
    • Combining Automatic Angle Correction and 3-D Tracking Doppler for the Assessment of Aortic Stenosis Severity 

      Fiorentini, Stefano; Espeland, Torvald; Berg, Erik Andreas Rye; Aakhus, Svend; Torp, Hans; Avdal, Jørgen (Journal article; Peer reviewed, 2019)
      Aortic valve stenosis (AS) is a narrowing of the aortic valve opening, which causes increased load on the left ventricle. Untreated, this condition can eventually lead to heart failure and death. According to current ...
    • Increased complement factor B and Bb levels are associated with mortality in patients with severe aortic stenosis 

      Shahini, Negar; Ueland, Thor; Auensen, Andreas; Michelsen, Annika; Ludviksen, Judith K; Hussain, Amjad Iqbal; Pettersen, Kjell; Aakhus, Svend; Espeland, Torvald; Lunde, Ida Gjervold; Kirschfink, Michael; Nilsson, Per; Mollnes, Tom Eirik; Gullestad, Lars; Aukrust, Pål; Yndestad, Arne; Louwe, Maria Cornelia (Journal article; Peer reviewed, 2019)
      Inflammation is involved in initiation and progression of aortic stenosis (AS). However, the role of the complement system, a crucial component of innate immunity in AS, is unclear. We hypothesized that circulating levels ...

    • YKL-40 (Chitinase-3-Like Protein 1) Serum Levels in Aortic Stenosis 

      Arain, Fizza Kanwal; Abraityte, Judita Aurelija; Bogdanova, Mariia; Solberg, Ole Geir; Michelsen, Annika; Lekva, Tove; Aakhus, Svend; Holm, Sverre; Halvorsen, Bente; Finsen, Alexandra; Vinge, Leif Erik; Nymo, Ståle Haugset; Espeland, Torvald; Ranheim, Trine; Aukrust, Pål; Vaage, Ingvar Jarle; Auensen, Andreas; Gullestad, Lars; Ueland, Thor (Peer reviewed; Journal article, 2020)
      BACKGROUND: Identification of novel biomarkers could provide prognostic information and improve risk stratification in patients with aortic stenosis (AS). YKL-40 (chitinase-3-like protein 1), a protein involved in ...
