Radial and longitudinal right ventricular function in children.

tematic evaluation of the RV in the pediatric population and want to encourage their research with new echocardiographic parameters, such as the RVWD. Their current work will enhance our knowledge about the normal RV functional pattern in childhood.1 I hope that with more and more available normal reference values and Z-scores for the pediatric population that quantification of RV function will become an easy, available tool for all sonographers.
