tricuspid annular plane systolic excursion
Also written as: TAPSE — tricuspid annular plane systolic excursion
Echocardiographic measurement of right ventricular systolic function based on longitudinal motion of the lateral tricuspid annulus.
Full Definition
A simple, reproducible echocardiographic parameter that assesses right ventricular systolic function by measuring the distance the lateral tricuspid annulus moves toward the cardiac apex during systole. TAPSE is obtained using M-mode echocardiography in the apical four-chamber view, placing the cursor through the lateral tricuspid annulus. Normal values are typically ≥17mm, with values <16mm suggesting right ventricular dysfunction. This measurement correlates with right ventricular ejection fraction and provides prognostic information in various cardiac conditions. TAPSE is particularly useful in cardiac surgery for assessing right heart function before and after procedures that may affect the right ventricle.
Usage
Usage note: Commonly abbreviated as TAPSE; report values in millimeters with reference to normal range (≥17mm).
