Tricuspid annular plane systolic excursion (TAPSE)

Tricuspid annular plane systolic excursion (TAPSE) can be measured with transesophageal echocardiography. In this image, a mid-esophageal four-chamber view is focused on the lateral tricuspid annulus and right ventricular apex. TAPSE is measured using speckle tracking software to determine the distance that the tricuspid annulus travels during systole, with normal value being 17 mm or greater.
