Interchangeability of Right Ventricle Longitudinal Shortening in Echocardiography

RV longitudinal shortening fraction (RV-SLF) is based on the analysis of the tricuspid annulus displacement (TAD) and can be performed in transthoracic (TTE) or transoesophageal echocardiography (TEE). Having an 2D-STE interchangeable parameter would allow accurate measurement of RV systolic function before, during and after cardiac surgery. However, to date, there are no data on the interchangeability of RV-LSF measurements performed in TTE and TEE.

The aim of the study is to evaluate the interchangeability of TTE and TEE measurements of RV-LSF during cardiopulmonary bypass surgery.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Adult patient (>18 years)
  • Patient hospitalized at the Amiens University Hospital for scheduled cardiac surgery under cardiopulmonary bypass.
  • Information of the patient and collection of his non-opposition

Exclusion criteria

  • Patient with a contraindication to the realization of TEE (gastric or mediastinal pathology)
  • Patient with poor echogenicity on TEE not allowing evaluation of 2D-STE parameters of the right ventricle
  • Patient with a rapid supraventricular rhythm disorder (HR > 100) at the time of TTE and/or TEE.

Treatment and study plan

transthoracic echocardiography (TTE)

Other

In order to evaluate the interchangeability of RV-LSF, a TTE will be performed just after the placement of general anesthesia, when the patient is under mechanical ventilation

transoesophageal echocardiography (TEE).

Other

During cardiopulmonary bypass surgery patients is monitored by a TEE as recommended.

Primary outcomes

  1. Variation of the RV-LSF (in %) between TTE and TEE

    Time frame: one day

    RV-LSF is : Right ventricular longitudinal shortening fraction. RV-LSF is an angle-independent and automatically calculated speckle-tracking parameter and reproducible parameter.
