About this study
This study is part of a research project in which new ultrasound-based techniques will be examined to improve clinical decision making for patients with aortic stenosis. These patients could develop increased amounts of myocardial fibrosis. This fibrosis is associated with the patients' prognosis. Fibrosis can be evaluated with magnetic resonance imaging (MRI), which unfortunately is quite expensive and not easily available. Ultrasound-based parameters will be developed for the assessment of the amounts of myocardial fibrosis, especially in the left ventricle. Then it will be examined whether these parameters can predict the patients magnitude of fibrosis and check for association with the patients prognosis. MRI will serve as a gold standard for quantification of myocardial fibrosis. The new echocardiographic techniques and parameters are expected to provide new insights in the interplay between aortic stenosis and left ventricular function, and to ultimately improve the care for patients with aortic stenosis.
The present study's objectives are:
- Quantify the level of myocardial fibrosis in mild, moderate, and severe aortic stenosis compared with a healthy population.
- Evaluate the patients outcome after one and three year of follow-up
- Conditions
- Aortic Valve Stenosis, Myocardial Fibrosis
- Being tested
- Echocardiography, MRI, Blood test, ECG and Holter-ECG, 6 min walking test

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EchocardiographyDiagnostic test
Also called GE Vingmed ultrasound scanner e95, 2017
Conventional transthoracic echocardiography will be performed, in addition 3D-imaging and acquisitions with high frame rate. The data from these patients will be anonymized and transferred for post-hoc analysis in dedicated computer software (GE Vingmed, EchoPac 2.0) and in validated machine learning algorithms.
MRIDiagnostic test
Also called Magnetic resonance imaging
Cardiac MRI will be performed. In all patients without contraindications a gadolinium-based contrast agent will be given.
Blood testDiagnostic test
Conventional brachial venous blood samples will be drawn. Blood samples will be analyzed for markers of myocardial fibrosis at Oslo University Hospital.The findings will be related to imaging findings.
ECG and Holter-ECGDiagnostic test
ECG/Holter-ECG will be performed, and the findings will be related to the imaging findings.
6 min walking testDiagnostic test
6 MWT will be performed, and the findings will be related to findings from MRI/echocardiography.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
A study testing Echocardiography, MRI and Blood test in people with Aortic Valve Stenosis and Myocardial Fibrosis, run by Norwegian University of Science and Technology at 1 site in Norway.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cardiovascular morbidity and mortality (time frame: 1 + 3 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03422770, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2023.
