Diagnostic Value of Echocardiographic Indices in Determining Right Atrial Pressure Compared to Catheterization in Pediatrics and Young Adults

This study demonstrated that echocardiographic indices, such as the Caval index and tricuspid valve E/E´ ratio, can be useful in non-invasive estimation of right atrial pressure. However, age-specific reference values and cut-off points for these indices should be considered to improve their accuracy.
