The prevalence and impact of preoperative RVSWI on morbidity and mortality after transcatheter aortic valve replacement (TAVR) is unknown. We To evaluate the possibility that an elevated right ventricular stroke-work index observed in acute respiratory failure correlates with less dead space ventilation, 20 patients requiring mechanical ventilation were studied. Ratio of physiologic dead space to tidal volume was used as an index of distribution of pulmonary perfusion. An inverse linear relationship was found between right Parameter Equation Normal Range; Left Ventricular Stroke Work (LVSW) SV x (MAP - PAWP) x 0.0136: 58 - 104 gm-m/beat: Left Ventricular Stroke Work Index (LVSWI) Stroke work (SW) refers to the work done by the ventricle to eject a volume of blood (i.e., stroke volume). The force that is applied to the volume of blood is the intraventricular pressure. Therefore, ventricular stroke work can be estimated as the product of stroke volume and mean systolic pressure during ejection. In a normal heart, this is The accuracy of RVCPI in detecting RV failure was compared with the criterion standard, the RV stroke work index (RVSWI) obtained through right heart catheterization in advanced heart failure patients referred for heart transplantation or LVAD implantation. Methods and Results.

The accuracy of RVCPI in detecting RV failure was compared with the criterion standard, the RV stroke work index (RVSWI) obtained through right heart catheterization in advanced heart failure patients referred for heart transplantation or LVAD implantation. Methods and Results. Right ventricular stroke work index (RVSWI) is a parameter of right ventricular function. The aim of our study was to determine the relationship between RVSWI and glomerular filtration rate (GFR Right ventricular (RV) function assessment plays a pivotal role in advanced systolic heart failure (HF) patients, improving risk stratification 1 and predicting the success of left ventricular assist device (LVAD) implantation.2, 3 In particular, a reduced RV stroke work index (RVSWI) is associated with severe RV failure after LVAD implantation.3, 4, 5, 6 stroke work index: a measure of the work done by the heart with each contraction, adjusted for body surface area; equal to the stroke volume of the heart multiplied by the arterial pressure and divided by body surface area; the normal stroke work index does not exceed 40 g/m 2 .

Treatment of RV failure in PAH relies on: decreasing afterload with drugs There is often confusion about the concept of “load independency” of indices of of type and severity of pulmonary hypertension, so that total stroke work is 1.3 mPAP

Sep 9, 2014 >15 mmHg, a right ventricular stroke work index <300 mmHg/mL/m2, CI, cardiac index; SVI, stroke volume index; RVSWI, right ventricular Feb 1, 2016 Background Right ventricular failure (RVF) is a major cause of morbidity and RV stroke work index (RVSWI) were also associated with RVF. Dec 12, 2016 This results in an RV stroke work which is almost one-fourth that of 10 to almost 40 sec with an anoxia/hypoxia index (AHI) of at least 15/hour, Stroke work index definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. Look it up now! Right Ventricular Stroke Work Index Calculator . Stroke Work Index refers to the work done by the heart at each contraction. Right Ventricular Stroke Work Index (RVSWI) aids in determining the RV workload and contractility based on invasive hemodynamics and patient characteristics. Studies have shown that patients with poor pre-lung transplant (LTx) right ventricular (RV) function have prolonged post-operative ventilation time and intensive care stay as well as a higher risk of in-hospital death. RV stroke work index (RVSWI) calculates RV workload and contractility.
