Reference values for right ventricular systolic function in the form of z-scores of the tricuspid annular plane systolic excursion (TAPSE). Data are from 640 patients, aged 1 day to 18 years, as described by investigators in Graz, Austria.

Calculate the z-scores of 21 common 2D and M-Mode echo measurements, related to
body surface area. Measurement sites include the mitral valve, left ventricle, aortic
valve, aortic arch, pulmonary valve, and pulmonary arteries. Data is from 782 patients
evaluated at the Children's Hospital of Michigan.
