      The European Association of Cardiovascular Imaging (EACVI) is committed to maintaining the highest standards of professional excellence in all aspects of cardiovascular imaging. The mission of the EACVI is to promote ...
    • Global longitudinal strain is a more reproducible measure of left ventricular function than ejection fraction regardless of echocardiographic training 

      Karlsen, Sigve; Dahlslett, Thomas; Grenne, Bjørnar; Sjøli, Benthe; Smiseth, Otto A.; Edvardsen, Thor; Brunvand, Harald (Peer reviewed; Journal article, 2019)
      Background: Left ventricular ejection fraction (LVEF) is an established method for evaluation of left ventricular (LV)systolic function. Global longitudinal strain (GLS) by speckle tracking echocardiography seems to be an ...
    • Myocardial Function Imaging in Echocardiography Using Deep Learning 

      Østvik, Andreas; Salte, Ivar Mjåland; Smistad, Erik; Nguyen, Thuy Mi; Melichova, Daniela; Brunvand, Harald; Haugaa, Kristina; Edvardsen, Thor; Grenne, Bjørnar; Løvstakken, Lasse (Journal article; Peer reviewed, 2021)
      Deformation imaging in echocardiography has been shown to have better diagnostic and prognostic value than conventional anatomical measures such as ejection fraction. However, despite clinical availability and demonstrated ...
    • Prognostic value of circulating microRNA-210 levels in patients with moderate to severe aortic stenosis 

      Røsjø, Helge; Dahl, Mai Britt; Bye, Anja; Andreassen, Johanna; Jørgensen, Marit; Wisløff, Ulrik; Christensen, Geir Arve; Edvardsen, Thor; Omland, Torbjørn (Journal article; Peer reviewed, 2014)
      Background: Circulating micro-RNAs have been proposed as a novel class of cardiovascular (CV) biomarkers, but whether they meet analytical requirements and provide additional information to establish risk indices have ...
    • Real-Time Automatic Ejection Fraction and Foreshortening Detection Using Deep Learning 

      Smistad, Erik; Salte, Ivar Mjåland; Østvik, Andreas; Melichova, Daniela; Nguyen, Thuy Mi; Haugaa, Kristina; Brunvand, Harald; Edvardsen, Thor; Leclerc, Sarah; Bernard, Olivier; Grenne, Bjørnar; Løvstakken, Lasse (Peer reviewed; Journal article, 2020)
      Volume and ejection fraction (EF) measurements of the left ventricle (LV) in 2-D echocardiography are associated with a high uncertainty not only due to interobserver variability of the manual measurement, but also due to ...
    • Sepsis causes right ventricular myocardial inflammation independent of pulmonary hypertension in a porcine sepsis model 

      Pischke, Søren; Hestenes, Siv Merete; Johansen, Harald Thidemann; Fure, Hilde; Bugge, Jan F; Espinoza, Andreas Westenvik; Skulstad, Helge; Edvardsen, Thor; Fosse, Erik; Mollnes, Tom Eirik; Halvorsen, Per Steinar; Nielsen, Erik Waage (Journal article; Peer reviewed, 2019)
      Introduction Right ventricular (RV) myocardial dysfunction is a common feature in septic shock. It can worsen outcome, but the etiology is poorly understood. Pulmonary artery hypertension (PAH) plays a part in the ...
    • Treatment of sleep apnea in patients with paroxysmal atrial fibrillation: design and rationale of a randomized controlled trial
