It is particularly useful in intensive care and cardiac catheterization labs to evaluate right heart function. High values may indicate pulmonary hypertension or increased afterload, while low values suggest right ventricular failure. Inputs needed are SVI (stroke volume normalized to body surface area) and MPAP (average pressure in the pulmonary artery).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This calculator estimates the Right Ventricular Stroke Work Index (RVSWI), a key hemodynamic parameter used to assess right ventricular performance in patients with heart failure, pulmonary hypertension, or undergoing cardiac surgery.
