Clinical and echocardiographic parameters predicting 1- and 2-year mortality after transcatheter aortic valve implantation
(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 ... -
Echocardiographic assessment of diastolic dysfunction in elderly patients with severe aortic stenosis before and after aortic valve replacement
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)Background - The 2016 guidelines of the American Society of Echocardiography (ASE) and European Association of Cardiovascular Imaging (EACVI) for evaluation of left ventricular (LV) diastolic dysfunction by Doppler flow and tissue Doppler- echocardiography do not adjust assessment of high filling pressures for patients with aortic stenosis (AS). However, most of the studies on this patient group ... -
Global myocardial longitudinal strain in a general population—associations with blood pressure and subclinical heart failure: The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-18)The early detection of subclinical myocardial dysfunction can contribute to the treatment and prevention of heart failure (HF). The aim of the study was to (i) describe myocardial global longitudinal strain (GLS) patterns in a large general population sample from Norway and their relation to established cardiovascular disease (CVD) risk factors; (ii) to determine its normal thresholds in healthy ... -
Left atrial diameter, left ventricle filling indices, and association with all-cause mortality: Results from the population-based Tromsø Study.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-28)<p><i>Aims</i>: To examine the associations between diastolic dysfunction indices and long‐term risk of all‐cause mortality in adults over 23‐year follow‐up.</p> <p><i>Methods and results</i>: Participants (n = 2734) of the population‐based Tromsø Study of Norway had echocardiography in 1994–1995. Of these 67% were repeated in 2001 and/or 2007–2008. Mortality between 1994 and 2016 was determined ... -
Peak longitudinal strain most accurately reflects myocardial segmental viability following acute myocardial infarction - an experimental study in open-chest pigs
(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 ... -
Risk scores for prediction of 30-day mortality after transcatheter aortic valve implantation: Results from a two-center study in Norway
(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 ...
