Correlation of Transthoracic Echocardiographic Estimates of Right Ventricular Pressure with Right Ventricular Pressure Measurements on Cardiac Catheterization in Children with Pulmonary Hypertension
Authors' conclusion
In children with pulmonary hypertension, echocardiographic estimates of right ventricular pressure correlated moderately well with gold standard measurements by cardiac catheterization with stronger correlation in children with suprasystemic right ventricular pressures.
