Brief summary

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.

Interventions

OTHERtransthoracic echocardiography (TTE)

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

OTHERtransoesophageal echocardiography (TEE).

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

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
