Right atrial and right ventricular strain: prognostic value depends on the severity of tricuspid regurgitation

Assessing right heart function is challenging, particularly when significant tricuspid regurgitation (TR) is present. Among available echocardiographic techniques for assessment, literatures suggests that strain imaging may be more reliable and less susceptible to loading conditions. Thus, we aimed to assess the validity of RA and RV strain relative to conventional metrics as well as their utility in predicting patient outcomes in TR.
