About this study
Official title: Quantification of Myocardial Blood Flow in Cardiovascular Magnetic Resonance for Prediction of Fractional Flow Reserve in Coronary Catheterisation
Patients will undergo quantitative perfusion assessment in cardiovascular magnetic resonance imaging (dual bolus or dual sequence approach) as well as invasive coronary angiography for assessment of fractional flow reserve (FFR) including assessment of coronary flow reserve (CFR) and microcirculatory resistance (IMR).
- Conditions
- Chronic Coronary Syndrome
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| CCS patients | Clinical patients referred for ischaemia testing (CMR/coronary angiogram) will undergo the respective counterpart as well so that patients will have undergone both CMR and invasive testing. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quantitative Perfusion
Correlation of myocardial blood flow and perfusion reserve in CMR with invasively dervived fractional flow reserve (FFR), coronary flow reserve (CFR) and microcirculatory resistance (IMR)
Measured: assessment of CMR and invasive data within 24hours
Dual bolus vs dual sequence
Compare both CMR-derived quantitative perfusion for prediction of FFR/CFR/IMR
Measured: assessment of CMR and invasive data within 24hours
Secondary outcomes (3)
Strain
Correlation of segmental perfusion and myocardial strain
Measured: baseline CMR data
Tissue characterisation
Correlation of segmental perfusion and T1/T2/ECV/LGE
Measured: baseline CMR data
Cardiovascular Hospitalisation (CVH)
CVH within 12 months
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Coronary Syndrome, run by Kerckhoff Klinik at 1 site in Germany.
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 2 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: opening soon, as of the sponsor's last update on 18 Jun 2025. 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 Germany. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Sören Jan Backhaus, MD (06032-996-2620, s.backhaus@kerckhoff-klinik.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quantitative Perfusion (time frame: assessment of CMR and invasive data within 24hours). The study lists 2 primary outcomes in all. 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 18 Jun 2025.
