WebThe right ventricular–pulmonary arterial coupling ratio (Ees/Ea) also exhibited heterogeneity (B) during therapy, with no improvement or even a decrease in some subjects. End-diastolic elastance (Eed) showed a decrease by 48 hours (C). There was a nearly universal increase in right ventricular ejection fraction (RVEF) (D). WebDespite such high shunt fractions, patients were able to maintain normal pulmonary blood flow and tissue oxygen delivery during exercise. The authors postulated that exercise tolerance was relatively well-maintained due to a lower than normal pulmonary vascular resistance (mean, 32 dyn · s · cm −5 ), which allowed them to appropriately augment …
