Details and patient eligibility

About

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.
