Detailed Description
Cardiac Magnetic Resonance Imaging (MRI) is an activity of the Bordeaux University Hospital that continues to grow (+7.3% in 2021 compared to 2019) under the combined effect of the increase in activity of cardiology care channels and the extension of clinical indications for cardiac MRI. Indeed, cardiac MRI has become an essential examination in the diagnosis of many heart diseases and is little practiced elsewhere in New Aquitaine. The current delay for a cardiac MRI is 3 and a half months.
In this context, it is necessary to be efficient because any procedure failure, examination interruption or insufficient image quality can delay the diagnosis and therapeutic management of the patient for several months. Numerous studies have shown that anxiety induces interruptions in the acquisition of MRI images and repetition of sequences, thus prolonging the examination time.
However, no study takes into account the specificity of cardiac MRI, whose image quality is intimately linked to the patient's cooperation and to the synchronization of the sequences with the heart rhythm.
Hypnosis seems to be adapted to reduce the patient's anxiety, by allowing him to ignore the surrounding reality while remaining in relation with the attendant.
The hypothesis is that by reducing patient anxiety through hypnosis, image quality in cardiac MRI would be improved.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Anxious patients with hypnosis Hypnosis support before, during and at the end of cardiac MRI exam |
Other: Hypnosis
Hypnosis support before, during and at the end of cardiac MRI exam
|
| No Intervention: Anxious patients without hypnosis Cardiac MRI exam accordingly to usual care |
|
| No Intervention: Non anxious patients Cardiac MRI exam accordingly to usual care |
Outcome Measures
Primary Outcome Measures
- quality of cardiac MRI images [Baseline]
Likert score measurements
Secondary Outcome Measures
- number of artifacts [Baseline]
The number of artifacts will be estimated with European CMR Registry objective score.
- Diagnostic validation score [Baseline]
The diagnostic validation score for the entire examination (and not sequence by sequence) makes it possible to define whether, despite the presence of artifacts, the examination makes it possible to answer the question initially asked in the examination request.
- Causality score measurement [Baseline]
Causality score measurement for examinations with a Likert score < 4
- Overall duration [Baseline]
The overall duration of the examination and the different phases (reception and preparation time, image acquisition time).
- Number of repeated or interrupted sequences [Baseline]
The number of repeated or interrupted sequences (by the Radiographer or the patient).
- Anxiety level [Baseline]
The Spielberg State Anxiety Index STAI-Y anxiety score will be used to estimate patient anxiety before and after the MRI.
- Post-MRI satisfaction score [Baseline]
The post-MRI satisfaction score will be estimated from the patient by a visual analog scale rated from 0 (not at all satisfied) to 10 (very satisfied).
