Study summary

Transoesophageal echocardiography (TOE) is a routine cardiology examination that is performed in most cases under local anaesthesia and is recommended for many indications.The objective of our study will be to evaluate the expected beneficial effect of using conversational hypnosis and hypnosis during a transoesophageal ultrasound examination performed directly in the examination room by the cardiologist conducting the examination.

Read the detailed description

Transoesophageal echocardiography is a routine cardiology examination that is performed in most cases under local anaesthesia and is recommended for a number of indications: stroke assessment, endocarditis screening, and heart valve evaluation. It involves inserting an ultrasound probe into the oesophagus through the patient's mouth in order to see the heart more closely and from a different angle. It is a useful and necessary examination in certain situations, but it can be uncomfortable for patients despite local anaesthesia. The examination can be performed under general anaesthesia, but this carries a risk of adverse effects (between 5 and 6%) for the patient and requires more extensive care (anaesthetist, prolonged monitoring during recovery).

The objective of our study will be to evaluate the expected beneficial effect of using conversational hypnosis and hypnosis during a transoesophageal ultrasound examination performed directly in the examination room by the cardiologist conducting the examination. The cardiologist will use the unavoidable time required to set up and explain the examination to use conversational hypnosis and will take additional, deliberately shortened time to perform 'light' hypnosis. The effectiveness of the combined use of a conversational hypnosis phase and a hypnosis phase will be compared, in terms of tolerance of the examination and time consumed, to a 'classic' interview conducted by a cardiologist not trained in these two techniques. In both situations, the explanation given to the patient will be complete and adapted to each patient's level of understanding and will be provided before the patient is in a state of hypnosis. If we can show that by using the necessary and unavoidable time to explain the examination to the patient, we can use conversational hypnosis and hypnosis techniques to improve the patient's comfort without excessive loss of time (>15 minutes) or the need for additional staff, this would highlight the value of using these techniques in daily practice and the expected benefits of training healthcare professionals.

Study arms

  • Experimental
    hypnosis' experimental group

    For the 'hypnosis' experimental group, the examination will be carried out in the usual room. Local anaesthesia will be administered by a nurse. A first cardiologist (a doctor trained in hypnosis) will be present to explain the procedure to the patient using conversational hypnosis. Once all the information has been provided and understood, he will use hypnosis to attempt to induce a trance (see section 1.4, procedure performed). A second cardiologist (operator) will perform the examination. As in the control group, the cardiologist trained in hypnosis will assist the operating cardiologist during the examination and may perform the examination himself if the first operator fails.

    Other: conversational hypnosis

  • No intervention
    control group

    For the control group, the examination will be performed according to standard practice. A nurse will administer local anaesthesia to the throat, then a first cardiologist (operator) will inform the patient about the examination procedure and perform the examination. A second cardiologist will assist the first operator and may perform the examination themselves if the first operator is unsuccessful after three attempts.

What researchers measure

Primary outcomes

  1. the degree of comfort felt during the procedure, measured on a visual analogue scale (VAS) (from 0 to 10) immediately after the examination

    The main evaluation criterion is the degree of comfort felt during the operation, measured on a visual analogue scale (VAS) (from 0 to 10) immediately after the examination. The question asked will be 'During the procedure, how comfortable were you?'

    Time frame: 1 day

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2026 (actual). Primary completion is estimated for Oct 2028, 31 months after the start.

Of 3,108 non-industry interventional studies with no phase under Stroke, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 46. This study's planned 31 months is above that.

Counting every sponsor, half of 3,252 studies reached it within 23 months; a quarter within 10 and three quarters within 46.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
