🫀 Right Ventricular Stroke Work Index (RVSWI)
UseWhen to use: PH / RV failure / LVAD planning adjunct with RHC data.
StrataLow RVSWI with rising RAP suggests impaired RV stroke work relative to afterload.
LimitsWhen not to use: poor RAP zero. · Pitfall: asynchronous pressures. · Pair with PAPi / imaging.

When to use
When to use: PH / RV failure / LVAD planning adjunct with RHC data.
How it works
RVSWI = 0.0136 × SVI × (mPAP − RAP).
Key points
- 0.0136 × SVI × (mPAP−RAP).
- RV performance adjunct.
- Next: PAPi / PVR.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

FAQ
Frequently asked questions
- Does Right Ventricular Stroke Work Index (RVSWI) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Right Ventricular Stroke Work Index (RVSWI) calculated in practice? Can you show a worked example?
- Inputs: SVI source SV + BSA, SVI 40 mL/beat/m², Stroke volume 70 mL, BSA 1.8 m², Cardiac index 2.8 L/min/m², Heart rate 80 /min, Mean PA pressure (mPAP) 25 mmHg, RAP / CVP 8 mmHg → Result: RVSWI 9.0 g·m/m²（SVI used: 38.9 mL/beat/m², mPAP−RAP: 17.0 mmHg, Cue: 5–10 — intermediate RVSWI band） Inputs: SVI source Direct SVI, SVI 40 mL/beat/m², Stroke volume 70 mL, BSA 1.8 m², Cardiac index 2.8 L/min/m², Heart rate 80 /min, Mean PA pressure (mPAP) 25 mmHg, RAP / CVP 8 mmHg → Result: RVSWI 9.2 g·m/m²（SVI used: 40.0 mL/beat/m², mPAP−RAP: 17.0 mmHg, Cue: 5–10 — intermediate RVSWI band）
