A total of up to 100 consecutive subjects of both genders will be enrolled at the Sheba Medical Center. The study procedures, clinical management and follow up will be done at the Sheba Medical Center.
Who may be able to join

About this study
Official title: Clinical Outcome of Patients With Low Ejection Fraction or Low-gradient Severe Aortic Stenosis
To assess the ability of baseline clinical parameters and imaging modalities to predict short and long term left ventricular function and clinical outcome of subjects with low-gradient, severe aortic stenosis.
To assess the impact of aortic valve replacement as compared to medical therapy on clinical outcome of patients with low-gradient, severe aortic stenosis.
To assess possible impact of aortic annulus assessment using 3-dimensional imaging modalities on the assessment of AS severity and definition of low gradient severe aortic stenosis.

Questions about this trial
What is this clinical trial studying?
An observational study of Aortic Stenosis, run by Sheba Medical Center at 1 site in Israel.
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 3 inclusion and 3 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: paused, as of the sponsor's last update on 29 Nov 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 Israel. 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?
Results are not available in the source record.
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?
Change in left ventricular ejection fraction after aortic valve replacement (time frame: 2±1 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 29 Nov 2023; AzTrials last refreshed its copy on 7 Nov 2026.
