- Tricuspid annular plane systolic excursion (TAPSE) is a simple and reproducible parameter for quantitative assessment of the RV EF. It was first described by Kaul at al (Am Heart J. 1984).
- It is perfomed from an apical four chamber window using M mode across the annulus to evaluate longitudinal contraction.
- TAPSE >16mm is considered normal.
- TAPSE< 16mm indicates reduced RV Ejection fraction.
- AHA currently recommends TAPSE as one of the tool to assess RV Function. It is an independent prognostic marker in PE, IWMI, ARDS.
- Alternative to A4Cview subcostal view may be used in mechanically ventilated patients.
