INSIGHT

PASP Estimation

  • PASP, estimated via Doppler echo, isn't a direct pressure measurement.
  • It's calculated using the tricuspid regurgitant jet velocity and an equation.
ADVICE

Interpreting PASP

  • Be skeptical of PASP values from echo, as they can be off by over 10 mmHg.
  • Errors occur in both overestimation and underestimation.
ADVICE

Trending RV Function

  • Trend RV size and function over time in pulmonary hypertension patients.
  • Don't focus solely on PASP values.
