HeartGuide: Preliminary Study

Echocardiography is the examination of choice for the study of cardiac pathologies. Interest of echocardiography for other medical specialties has already been demonstrated (intensive care in the case of hemodynamic failure - in intra and extra hospital emergency medicine for the initial assessment of chest pain or dyspnea).

The expansion of echocardiography'use has been catalyzed by miniaturization of echographic systems and decrease in their price. Recently, probes directly connected to a tablet or phone have been developed at a limited cost.

Therefore, it's possible to consider these ultrasound scanners as the new stethoscope that could be used by any health professional.

The last limit to this democratization is the training, especially for non-specialists (non-cardiologists).

About this study

Since January 2019, echocardiography laboratory headed by Prof. Stéphane Lafitte and DESKi (start-up - Bordeaux) have been working on guiding non-experts through their cardiac ultrasound examination.

An algorithm indicating in real time if the view obtained corresponds to a reference view has already been validated. However, this algorithm does not tell the operator which movement would improve the image quality.

Thanks to advances in deep learning and by combining cardiac ultrasound acquisitions with systems that record the position of the probes in real time, it would be possible to develop an algorithm able to guide the operator's movements.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients (male or female) older than 18 years,
  • Patient having a scheduled cardiac ultrasound outside any emergency context,
  • Patients who have not objected to participating in the research (at the latest on the day of inclusion and before any examination required by the research),
  • Subjects affiliated or benefiting from a social security plan,
  • Women of childbearing age who are using effective contraception.

Treatment and study plan

recording of the probe position

Other

For each patient, a cardiac ultrasound acquisition will be performed with an optical tracking system (infrared) recording the probe's position in real time.

Primary outcomes

  1. Probe position

    Time frame: Day 0

    Difference between actual probe position and predicted position with guidance algorithm

Secondary outcomes

  1. Percentage of matches between algorithm and expert

    Time frame: Day 0
