The Pre-brief

What is TAPSE and why is it so important to Resuscitationists?

The Debrief

  • Pearl #1: TAPSE stands for Tricuspid annular plane systolic excursion, and it’s a measure that correlates well with RV ejection fraction
  • Pearl #2: TAPSE is measured in an apical 4 chamber view, ideally focused on the right ventricle, using M Mode to accurately measure the vertical movement of the lateral tricuspid annulus.
  • Pearl #3 TAPSE is limited as it is angle-dependent and only focuses on one movement (vertical) of the RV’s complex 3-dimensional actions. You can have normal TAPSE with a dysfunctional RV!
