Validation study on the accuracy of echocardiographic measurements of right ventricular systolic function in pulmonary hypertension.
The accuracy of echocardiographic parameters of right ventricular (RV) function has not been sufficiently validated in patients with pulmonary hypertension (PH). The aim of this study was to evaluate whether echocardiographic measurements reliably reflect RV systolic function in PH using cardiac magnetic resonance imaging (CMRI)-derived RV ejection fraction (RVEF) as a gold standard. ⋯ Echocardiographic measurements are promising noninvasive indices of RV systolic function in patients with PH. In particular, TAPSE is superior to other indices in accuracy.

Pulmonary artery systolic pressure (PASP) is frequently measured noninvasively using transthoracic echocardiography. Normal values of PASP are based on studies performed in heterogeneous populations. The normal values of PASP in young healthy subjects are poorly defined. The aim of this study was to describe the distribution and clinical and morphologic correlates of PASP values in young healthy subjects. ⋯ PASP in young, physically fit subjects may be higher than previously reported in the general population and is poorly explained by age, blood pressure, and other echocardiographic parameters.
