RV stroke work index (RVSWi) poses as a potential predictor of outcome.

RVSWiRHC was computed as (mPAP-mRAP)\u00d7SViRHC, (mPAP, mean pulmonary arterial pressure; mRAP, mean right atrial pressure; SVi, stroke volume indexed to body surface area). ECHO-derived RVSWi was calculated as RVSWiECHO-Mean = TRmeanPG \u00d7 SViECHO and RVSWiECHO-Max = TRmaxPG \u00d7 SViECHO (TRmeanPG and TRmaxPG: tricuspid regurgitant mean and maximum pressure gradient). Invasive sPAP, mPAP, and pulmonary vascular resistance decreased and SVi increased from baseline to follow-up (P &amp;lt; 0.01 for all). RVSWiRHC and RVSWiECHO (Mean and Max) did not differ from baseline to follow-up (P &amp;gt; 0.05). Forty patients died during 109 \u00b1 24 months. In univariate Cox proportional hazard analysis, age &amp;gt; 65 years, 6-minute-walk test &amp;lt; 160\u2005m, WHO class III-IV and indexed right atrial volume were associated with long-term mortality, but none of the RVSWi methods.
