    • Clinical and echocardiographic parameters predicting 1- and 2-year mortality after transcatheter aortic valve implantation 

      Kjønås, Didrik; Schirmer, Henrik; Aakhus, Svend; Eidet, Jo; Malm, Siri; Aaberge, Lars; Busund, Rolf; Røsner, Assami (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-06)
      <p><i>Background:</i> Transcatheter aortic valve implantation (TAVI) has become a standard treatment option for patients with symptomatic aortic stenosis. Elderly high-risk patients treated with TAVI have a high residual mortality due to preexisting comorbidities. Knowledge of factors predicting futility after TAVI is sparse and clinical tools to aid the preoperative evaluation are lacking. The aim ...

    • Direct angiography demonstrates equal 8-12 years patency rates of radial artery and saphenous vein grafts 

      Bahar, Ramez; Dahl-Eriksen, Øystein; Busund, Rolf; Dahl, Per Erling; Hermansen, Stig Eggen; Iqbal, Amjid; Mannsverk, Jan; Myrmel, Truls; Steigen, Terje; Trovik, Thor; Sørlie, Dag Glen; Bartnes, Kristian (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-30)
      Objectives: The benefits of coronary artery bypass surgery depend on lasting graft patency. To aid rational graft selection, the relative long-term merits of radial artery and saphenous vein grafts need to be determined by a gold standard method and with minimal clinically driven selection bias. Methods: The patency rates of various conduits were determined by direct angiography in 76 patients from ...

    • Hypothermic cardiac arrest far away from the center providing rewarming with extracorporeal circulation. 

      Mark, Eckhard; Jacobsen, Olaf; Kjerstad, Astrid Kristine; Næsheim, Torvind; Busund, Rolf; Bahar, Ramez; Jensen, Jon Kjetil; Skorpen, Per Kristian; Bjertnæs, Lars J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      A 41-year-old man suffered hypothermic cardiac arrest after water immersion and was transported to our university hospital by ambulance helicopter for rewarming on cardiopulmonary bypass. He resumed spontaneous cardiac activity 6 h 52 min after cardiac arrest and recovered completely.

    • Peak longitudinal strain most accurately reflects myocardial segmental viability following acute myocardial infarction - an experimental study in open-chest pigs 

      Aarsæther, Erling Johan; Røsner, Assami; Straumbotn, Espen; Busund, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The extension and the transmurality of the myocardial infarction are of high predictive value for clinical outcome. The aim of the study was to characterize the ability of longitudinal, circumferential and radial strain measured by 2-dimensional speckle tracking echocardiography (2D-STE) to predict the extent of necrosis in myocardial segments following acute myocardial infarction and to separate ...

    • Plasmapheresis in severe sepsis and septic shock: a prospective, randomised, controlled trial 

      Busund, Rolf; Koukline, Vladimir; Utrobin, Uri; Nedashkovsky, Edvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2002-07-23)
      Objective: To determine the therapeutic efficacy and safety of plasmapheresis in the treatment of patients with severe sepsis and septic shock. <br>Design: Prospective, randomised, clinical trial with a planned, midstudy, interim analysis. <br>Setting: Intensive care unit in a university hospital in Archangels, Russia. <br>Patients: Consecutive patients with severe sepsis or septic shock. <br ...

    • Predictors of early mortality after transcatheter aortic valve implantation 

      Kjønås, Didrik; Dahle, Gry; Schirmer, Henrik; Malm, Siri; Eidet, Jo; Aaberge, Lars; Steigen, Terje; Aakhus, Svend; Busund, Rolf; Rösner, Assami (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-23)
      <p><i>Objectives - </i>To investigate whether preoperative echocardiographic evaluation of ventricular function, especially right ventricular systolic and diastolic parameters including speckle-tracking analysis, could aid in the prediction of 30-day mortality after transcatheter aortic valve implantation (TAVI) in patients with aortic stenosis. <p><i>Methods - </i>This is a prospective observational ...

    • The risk factors for radial artery and saphenous vein graft occlusion are different 

      Bahar, Ramez; Hermansen, Stig Eggen; Dahl-Eriksen, Øystein; Busund, Rolf; Dahl, Per Erling; Iqbal, Amjid; Mannsverk, Jan Torbjørn; Myrmel, Truls; Steigen, Terje; Trovik, Thor; Sørlie, Dag Glen; Bartnes, Kristian (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-02)
      Objectives. To determine risk factors for radial artery and saphenous vein graft occlusion during long-term follow-up after coronary artery bypass grafting (CABG). Methods: From a cohort of 119 patients who had received a radial artery graft, 76 – of whom 55 also had at least one saphenous vein graft – underwent a preplanned direct angiography and anthropometric, biochemical, and endothelial ...

    • Risk scores for prediction of 30-day mortality after transcatheter aortic valve implantation: Results from a two-center study in Norway 

      Kjønås, Didrik; Schirmer, Henrik; Malm, Siri; Eidet, Jo; Aaberge, Lars; Steigen, Terje; Aakhus, Svend; Busund, Rolf; Røsner, Assami; Dahle, Gry (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-06)
      Objectives: Transcatheter aortic valve implantation (TAVI)-specific risk scores have been developed based on large registry studies. Our aim was to evaluate how both surgical and novel TAVI risk scores performed in predicting all cause 30-day mortality. In addition, we wanted to explore the validity of our own previously developed model in a separate and more recent cohort.<p> <p>Methods: The ...

    • Transcatheter aortic valve implantation (from inception to standard treatment): a single-center observational study 

      Høydahl, Martin Petter; Busund, Rolf; Rösner, Assami; Kjønås, Didrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-15)
      Background: Treatment of severe aortic stenosis with transcatheter aortic valve implantation (TAVI) was introduced in 2002. Since then, TAVI has become the primary treatment approach worldwide for advanced-age patients and younger patients with severe comorbidities. We aimed to evaluate the changes in patient demographics, complications, and mortality rates within 13 years.<p> <p>Methods: This ...
