- Look for septal shift and the relative size of the LV and RV. Septal shift may be in diastole, systole or both, indicating volume or pressure overload.
- In addition to TAPSE and S’, look at the RV free wall and fractional area of change.
- The relative size of the atria, atrial septal shift, and the IVC also provide clues to right ventricular filling pressures and performance.
