Echocardiographic evaluation of right ventricular systolic function remains subject to debate because of the anatomic peculiarities of the right ventricle. Several methods have been developed for quantifying right ventricular systolic function. The aim of this study was to determine the reliability and reproducibility of a number of echocardiographic parameters by evaluating their inter-observer and intra-observer variability. ⋯ The most reliable and reproducible echocardiographic parameters for evaluating right ventricular systolic function in patients with isolated mitral valvulopathy were the TAPSE and the tricuspid annular peak systolic velocity.
