NCT02770183

Brief Summary

The rational of the study is the description of the evolution of systolic cardiac function post-stunning, evaluated by transesophageal minimally invasive echocardiography (hTEE). The uses of these non-invasive methods have proved to be accurate for the qualitative and semi-quantitative determination of the contractile function of the left ventricle and the volume status of the patient. Furthermore the use of this technique has been demonstrated to be a reliable method to analyze the stunning recovery infarction after controlled cardiac arrest during the extra-corporeal circulation.

Outcome Measures

Primary Outcomes (1)

  • Fractional Area Change analysis

    Primary outcome is the evolution of Fractional Area Change for the duration of the study. The assessment of cardiac contractile function, which method is better described below, will be based mainly on a serial analysis of the Fractional Area Change and semi-quantitative assessment of ejection fraction in projection 4 cavities.

    72 hours

Secondary Outcomes (1)

  • Stratify patients

    72 hours

Study Arms (1)

Consecutive patients

Consecutive patients waiting to have elective cardiac surgery will be eligible. Each week the principal investigator will track patients in the operating program. The day of the consultation or the day before the operation, one of the investigators will have a talk with the patient to provide information and clarify doubts, also allowing the patient to read and look good all the details before giving its approval. For the screening, the principal investigator will use the criteria of inclusion and exclusion to select patients for the study. The screening uses clinical, laboratory or without other biological information. To minimize confounding factors, it will be taken consecutive patients, that will also be analyzed regarding all known variables that can affect the systolic function, as non-modifiable (age, cardiovascular risk factors, heart-rate variability and preoperative basal systolic function) and modifiable.

Interventions

ImacorDEVICE

In ICU, the doctors in charge places the probe in the esophagus, executing a series of morphological evaluations and semi-quantitative evaluations. Each image is saved as a video loop or a static image, to have a basic data for each patient and perform an off-line analysis. At the end of the first recording, the esophageal probe is left in the neutral position in the stomach, to eliminate any risk associated with a local increase of pressure. During the stay in the intensive care unit until the end of the study, the esophageal probe will be left in the neutral position, to run every two hours a new echocardiographic assessment on the main window, similar to the first evaluation, always recording loop-video and photographs, to have a time course of recovery of cardiac contractile function. All images will be stored in a digital archive.
