Noninvasive Estimation of Right Ventricular Filling Pressure by Ratio of Early Tricuspid Inflow to Annular Diastolic Velocity in Patients with and Without Recent Cardiac Surgery

Few data are available on the evaluation of right ventricular (RV) diastolic function and filling pressures by echocardiography. We aimed to determine whether the ratio of early tricuspid inflow to annular diastolic velocity (E/E') could be used to estimate RV filling pressure in patients with and without recent cardiac surgery.In all, 101 data sets including invasive and echocardiographic measurements (42 after recent cardiac surgery) were...
