RVSP/Pulmonary Hypertension Workup – Quick Reference

RVSP / PH Workup – Quick Reference

Enter what you have (TR Vmax and RAP, or RVSP and RAP). The tool will solve the missing value, classify PH likelihood, and suggest next steps.

Inputs

TR Vmax

m/s

RAP

mmHg

RVSP

mmHg

Assume no RVOT/PR obstruction (PASP ≈ RVSP)

Formula: RVSP = 4 × (TR Vmax)² + RAP

Supportive Echo Signs (check what’s present)

Category A – RV/RA

RV basal diameter > 41 mm
RA area > 18 cm²
TAPSE < 17 mm
S′ (TDI) < 9.5 cm/s
RV FAC < 35%

Category B – Septum/LV

Septal flattening (D-shaped LV)
LV eccentricity index > 1.1

Category C – PA/IVC

PA diameter > 25 mm
IVC > 21 mm with poor collapse
PAAT < 105 ms (if available)

Symptoms / Context (optional)

Unexplained dyspnea
Syncope/presyncope
Signs of right-sided congestion

Risk for CTEPH (prior PE/DVT)
Connective tissue disease, portal HTN, HIV, drugs/toxins
Chronic lung/OSA/ILD

Reference cutoffs & logic (tap to view)

• TR Vmax ≤ 2.8 m/s (RVSP ≲ 36 mmHg with RAP 3–5): PH unlikely.
• TR Vmax 2.9–3.4 m/s (RVSP ~ 37–50 mmHg): PH possible.
• TR Vmax > 3.4 m/s (RVSP > 50 mmHg): PH likely.
• Upgrade suspicion if ≥2 supportive signs across ≥2 categories (A/B/C).
• Assume PASP ≈ RVSP only if no RVOT obstruction or significant PR.
