Right Ventricular Oscillatory Power Is a Constant Fraction of Total Power Irrespective of Pulmonary Artery Pressure

Abstract

In this study, oscillatory power fraction is constant at 23% in non-PH and IPAH, implying that a considerable amount of power is not used for forward flow, making the RV less efficient with respect to its arterial load. Our findings emphasize the need to develop new therapy strategies to optimize RV power output in PAH.
