Background Assessment of right ventricular ( RV ) function remains challenging because of its complex geometry. Application of speckle‐tracking echocardiography ( STE ) to the tricuspid annulus provides rapid and automated assessment of the midpoint of the tricuspid annular plane displacement ( TAD ). The aim of this study was to investigate the value of tissue‐tracking TAD for the assessment of RV systolic dysfunction. Methods We retrospectively studied 61 patients in whom RV ejection fraction ( EF ) measured by 3‐dimensional echocardiography was performed. STE ‐derived displacement of the midpoint between the septal and lateral tricuspid annulus and its percentage of RV length at end‐diastole ( MTAD ) were automatically assessed. We performed comparative analyses between the RVEF ≥45% group and the RVEF <45% group in each parameter for the assessment of RV systolic function. Results MTAD was successfully assessed in 56 (91.2%). According to receiver operating characteristics analysis, RVEF <45% was best detected by MTAD <14.7% with area under curve ( AUC ) 0.97, sensitivity 93%, specificity 95%, followed by RV free wall longitudinal strain ( AUC 0.86), RV fractional area change ( AUC 0.84), tricuspid annular plane systolic excursion ( AUC 0.79), and systolic peak velocity of tricuspid annulus ( AUC 0.70), although there was no significant difference between MTAD and RV free wall strain ( P = 0.14). Conclusion The present study showed that MTAD was simple index and useful for the assessment of RV systolic dysfunction.
