摘要
RV function is an important component of overall heart function with prognostic value in predicting symptomatic limitation and outcome in different cardiovascular pathologies. RV longitudinal contraction accounts for the majority of total RV function, up to 80%, as compared to transverse shortening. Calculation of RV volume and RV ejection fraction (RVEF) remains hampered by the complex RV geometry and we lack a good geometric model allowing the calculation of right ventricular ejection fraction; secondly, the large apical trabeculations of the right ventricle make the endocardial delineation more difficult to obtain than for the left ventricle. To notice, the gold standard method for the assessment of the chamber (MRI) is resource intensive and cannot be employed in many settings. Considering these problems, multiple parameters have been developed for the evaluation of RV systolic function: tricuspid annular plane systolic excursion (TAPSE), systolic excursion velocity (S'), and longitudinal strain by speckle tracking.
