RV systolic function
RV systolic function is reported from TAPSE, S', FAC, RIMP, and 3D EF when those measurements are available.

Simple approach
Use TAPSE and S’ as quick longitudinal function markers. Add FAC when the endocardial border is traceable. Use 3D EF when a reliable RV 3D data set is available.
Detailed tutorial
RV systolic function should not rely on one metric when the image quality or loading condition is challenging. TAPSE and S’ emphasize longitudinal motion. FAC adds an area-based view of global systolic change. RIMP can provide a Doppler timing index, and 3D EF is useful when the acquisition is adequate.
| Measurement | Practical note |
|---|---|
| TAPSE | Fast and reproducible, but angle and tethering dependent |
| S’ | Tissue Doppler longitudinal velocity |
| FAC | Needs clear ED and ES borders |
| RIMP | Uses isovolumic and ejection timing |
| 3D EF | Best geometric representation when data quality is good |
Warning
Interpret RV function with clinical context in significant TR, pressure overload, post-operative states, or suboptimal RV-focused views.
