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.

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

Variation of the RV-LSF (in %) between TTE and TEE
RV-LSF is : Right ventricular longitudinal shortening fraction. RV-LSF is an angle-independent and automatically calculated speckle-tracking parameter and reproducible parameter.
