  1. Participants will be able to perform TAPSE to evaluate for right heart strain
  2. Participants will be able to use measurements of the RV to differentiate acute vs chronic right heart strain


  1. Introduction
    1. Brief review of RV dilation
  2. TAPSE
    1. Review apical 4 chamber (A4C) view needed to obtain TAPSE (Tricuspid Annular Plane Systolic Excursion)
      1. TAPSE <16mm linked to higher 30d mortality
      2. Acute vs Chronic: During End Diastole, if RV free wall ≥5mm most likely chronic and if <5mm most likely acute
    2. Review evidence behind TAPSE
    3. Review pathology videos
