Tricuspid annular plane systolic excursion (TAPSE) is a parameter of global right ventricular function. TAPSE is the displacement of the tricuspid annulus in systole, normally about 18-22 mm. It is measured by M-mode echocardiography with the curser over the lateral aspect of the tricuspid annulus. Measure the distance of the maximal longitudinal displacement and obtain the average of three consecutive cardiac cycles. TAPSE correlates well with other measures of right ventricular function such as RV ejection fraction. TAPSE can be used to diagnose pulmonary embolism, as it is significantly reduced in patients with PE. TAPSE can also be used to assess response to therapies for PE and determine prognosis. Place the M-mode cursor over the lateral aspect of the tricuspid annulus. Measure the distance of the maximal longitudinal displacement. Calculate the average of three consecutive cardiac cycles
