Echocardiographic Grading of Right Ventricular Afterload in Left Heart Disease: Relation to Right Ventricular Function, Pulsatile and Resistant Load, and Outcome.

ABSTRACT: The hemodynamic definitions of pulmonary hypertension consider resistive loading (pulmonary vascular resistance [PVR]), but there are increasing evidence that pulsatile loading (pulmonary artery compliance [PAC]) has functional and prognostic importance. The aims of the present study on patients with left heart disease, were to evaluate a novel echocardiographic right ventricular (RV) afterload score and to investigate its relation to risk of mortality or implantation of a left ventricular assist device. Patients (n = 220) with left ventricular ejection fraction < 50% consecutively referred for heart transplant or heart failure workup underwent echocardiography and right heart catheterization. Four metrics were included in the afterload score: the systolic pulmonary artery pressure
