Automatic measurements of left ventricular volumes and ejection fraction by artificial intelligence: clinical validation in real time and large databases
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-26)Aims - Echocardiography is a cornerstone in cardiac imaging, and left ventricular (LV) ejection fraction (EF) is a key parameter for patient management. Recent advances in artificial intelligence (AI) have enabled fully automatic measurements of LV volumes and EF both during scanning and in stored recordings. The aim of this study was to evaluate the impact of implementing AI measurements on acquisition ... -
Classic-Pattern Dyssynchrony Is Associated with Outcome in Patients with Fontan Circulation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-02)Background Morbidity and mortality increase as Fontan patients age into adulthood. Limited studies have examined cardiac magnetic resonance and echocardiographic parameters to predict death and transplantation in children after the Fontan operation. The aim of this study was to investigate echocardiographic parameters in adolescents and adults after Fontan operation, including myocardial mechanics ... -
Impact of Right Ventricular Geometry and Left Ventricular Hypertrophy on Right Ventricular Mechanics and Clinical Outcomes in Hypoplastic Left Heart Syndrome
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-24)<i>Background</i> - Right ventricular (RV) function is a major determinant of survival in hypoplastic left heart syndrome (HLHS). However, the relation of RV geometry to myocardial mechanics and their relation to transplant-free survival are incompletely characterized.<p> <p><i>Methods</i> - We retrospectively studied 48 HLHS patients from the Hospital for Sick Children, Toronto, (median ... -
Influence of hypertension on systolic and diastolic left ventricular function including segmental strain and strain rate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-22)Background - Left ventricular (LV) systolic and diastolic functions are important cardiovascular risk predictors in patients with hypertension. However, data on segmental, layer-specific strain, and diastolic strain rates in these patients are limited. The aim of this study was to investigate segmental two-dimensional strain rate imaging (SRI)-derived parameters to characterize LV systolic and ... -
Insomnia and sleep-disordered breathing in FKRP-related limb-girdle muscular dystrophy R9. The Norwegian LGMDR9 cohort study (2020)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-11)Limb-girdle muscular dystrophy R9 (LGMDR9) is a progressive and disabling genetic muscle disease. Sleep is relevant in the patient care as it impacts on health, functioning, and well-being. LGMDR9 may potentially afect sleep by physical or emotional symptoms, myalgia, or sleep-disordered breathing (SDB) through cardiorespiratory involvement. The objective was to investigate the occurrence of ... -
Post-traumatic stress disorder among heart disease patients: a clinical follow-up of individuals with myocardial infarction in the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-12)Background Myocardial infarction is likely to be experienced as a life-threatening and potentially traumatic event. Approximately one-third of patients with myocardial infarction experience clinically significant symptoms of anxiety/ depression. However, it is unclear how many of these patients experience these symptoms because of post-traumatic stress disorder (PTSD). We conducted a clinical screening ... -
Predictors of early mortality after transcatheter aortic valve implantation
(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 ... -
Transcatheter aortic valve implantation (from inception to standard treatment): a single-center observational study
(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 ... -
Virtual dissection of cardiac motion : what do we measure by strain and strain rate imaging?
(Doctoral thesis; Doktorgradsavhandling, 2010-09-17)Since the introduction of strain and strain rate measurements in echocardiography of the heart, many studies have demonstrated that these parameters quantify effectively and precisely regional myocardial deformation. The method allows to measure and quantify regional myocardial function. Different cardiac diseases might be detected at an earlier stage. However, there are many factors influencing ...
