Key result
Tricuspid annular plane systolic excursion correlated linearly with RV ejection fraction (r=0.69, P<0.001) and its optimal cut-off for detecting RV dysfunction varied with RV volume.
Why the study?
TAPSE is an effective parameter for assessing RV function in echocardiographic studies, but its preload dependency had not been explored.
Is tricuspid annular plane systolic excursion (TAPSE) dependent on right ventricular volume in addition to right ventricular function?
Observational (n=426)
Is tricuspid annular plane systolic excursion (TAPSE) dependent on right ventricular volume in addition to right ventricular function?
Effect estimate: r = 0.69
p-value: p=< .001
TAPSE is dependent on right ventricular volume in addition to function, meaning cut-off values for detecting RV dysfunction should be adjusted based on RV size.

TAPSE interpretation requires preload caution in altered volume states; leaves open prospective validation against CMR-derived RV function.
Zhao et al. (2019) conducted an observational in Right ventricular dysfunction (n=426). Tricuspid annular plane systolic excursion (TAPSE) was evaluated on Correlation of TAPSE with right ventricular ejection fraction (r = 0.69, p=< .001). Tricuspid annular plane systolic excursion correlated linearly with RV ejection fraction (r=0.69, P<0.001) and its optimal cut-off for detecting RV dysfunction varied with RV volume.
