ClinicalTricuspid valve annulus Excursion distance during systole by US.M-mode
Definition
Tricuspid annular plane systolic excursion (TAPSE) is the distance the tricuspid annulus is displaced during systole and is a reflection of right ventricular function. TAPSE is measured by M-mode ultrasound between end-diastole and peak systole, and a result of <17 mm is highly suggestive of right ventricular systolic dysfunction. [PMID: 25559473]
