Assessment of One-shot Cardiac-cervical-intracranial MRI in the Etiological Work up of Ischemic Stroke and Transient Ischemic Attacks (Concise)
March 5, 2021 updated by: Hospices Civils de Lyon
Stroke is a major public health issue in developed countries.
A full etiological work up within a short time is critical to implement the appropriate preventive treatment.
The etiological work up is actually based on a clinical examination and on a group of paraclinical examinations.
The realization of the standard strategy is time consuming, and increase the cost of the medical care.
A non-invasive one-shot examination of the heart, the aorta and the cervical and intracranial arteries (cci-MRI) could overcome these disadvantages.The investigator therefore propose to carry out an overall assessment of the performance of the cci-MR in the etiological work up of ischemic strokes and TIAs compared to the reference strategy

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Reference strategy
correspond to the reference techniques according to the current guidelines in the etiological work up of ischemic strokes and TIA
|
doppler ultrasound and/or angio CT-scan of the cervical arteries, angio CT-scan of the intracranial arteries, TTE wich can be supplemented by a TEE at the discretion of the investigator.
The TEE is not mandatory
|
Other: Evaluated strategy
correspond to perform the cci-MR: cardiac MRI with late-enhancement, angio-MRI of the cervical and intracranial arteries
|
of one-shot cardiac-cervical-intracranial MRI: cardiac MRI with late-enhancement, angio-MRI of the cervical and intracranial arteries
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To evaluate the consistency between the reference strategy and the cci-MR strategy for etiological work up according to the ASCOD classification, in ischemic stroke and TIA patients
Time Frame: Within 8 days after hospitalization
|
The primary endpoint will be based on the consistency for each patient of the etiological work up according to the ASCOD classification evaluated with cci-MR in comparison of the reference strategy
|
Within 8 days after hospitalization
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To assess the reproducibility of the assessment of the cci-MR results
Time Frame: Within 8 days after hospitalization
|
The reproducibility of the assessment of the cci-MR results will be based on the following endpoints: - Double reading; Concordance intra and inter reviewer |
Within 8 days after hospitalization
|
To evaluate the agreement between cci-MR and the reference method for each etiological subgroup: in the context of ischemic stroke or TIA.
Time Frame: Within 8 days after hospitalization
|
Agreement for each etiological subgroup between cci-MR and the reference method.
|
Within 8 days after hospitalization
|
To assess the improvement of the detection of myocardial scar with cci-MR compared to reference strategy
Time Frame: Within 8 days after hospitalization
|
Presence or absence of ischemic myocardial scar
|
Within 8 days after hospitalization
|
To assess the atherosclerotic burden (coronary, intracranial, cervical, aortic) assessed with cci-MR compared to the reference strategy,
Time Frame: Within 8 days after hospitalization
|
Presence or absence of coronary, intracranial, cervical, aortic atheroma.
The diagnostic work up will focus on cervical artery stenosis ≥ 50%; aortic arch atheroma ≥ 4 mm; intracranial artery stenosis ≥ 50% and presence of ischemic myocardial scar.
The scar pattern was classified as ischemic if its distribution was sub-endocardial to transmural within a coronary vascular territory and if scar was associated with segmental systolic dysfunction on corresponding cine images.
Atherosclerotic burden will be classified in 0, 1, 2, 3 and 4 atherosclerotic levels according to the number of arterial territories affected by at least one significant abnormality.
|

Time Frame: Within 8 days after hospitalization
|

|

|
To assess the rate of TEE recommended according to the opinion of the expert committee from data obtained with cci-MR and the reference strategy
Time Frame: Within 8 days after hospitalization
|
Presence or absence of recommendation to realize a TEE according to the opinion of the expert committee from data obtained with cci-MR and with the reference strategy

Time Frame: Within 8 days after hospitalization
|
Presence or absence of recommendation of having antiplatelet, anticoagulant, and of having a specific care (carotid surgery, PFO closure…) according to the opinion of the expert committee from data obtained with cci-MR and with the reference strategy
|

To assess the feasibility of the examinations (rate of completed examinations, deadline to obtain each examination, deadline to obtain all examinations including in each strategy)
Time Frame: Within 8 days after hospitalization
|
Presence or absence of full completed examinations, deadline between the date of ischemic stroke or TIA and each examination, deadline between the date of ischemic stroke or TIA and the end of all examinations including in each strategy
