Pediatric and Fetal Echo Z-Score Calculators
By Justin
The free Pediatric and Foetal echo Z score calculators allow you to generate z-scores and reference values (normal values) for Pediatric and Foetal echo using data compiled from medical literature and publications
Click to select the Calculator you want to use
Aortic Root Z-Scores
Calculate BSA-adjusted z-scores of the aortic annulus and sinuses of Valsalva using data published by Boston Children’s Hospital. (Updated 11/2008: added percentiles)
Ascending Aorta Z-Scores
Z-Scores of the ascending aorta (AAO) and aortic root. Data from the Children’s Heart Center, Halifax, Nova Scotia, published in 2006 and from Hôpital Bichat, Paris, France published in 2010
Cardiac Valve Z-Scores
Calculate BSA-adjusted z-scores of the mitral valve, tricuspid valve, aortic valve, and pulmonary valve using data published by Cincinnati Children’s Hospital. This data is also used to create dynamic z-score tables.
Coronary Artery Z-Scores
Calculate BSA-adjusted z-scores of the proximal coronary arteries (for patients with Kawasaki disease) using data published by Boston Children’s Hospital and Children’s National Medical Center, Washington, DC and Montreal, Canada (also calculates aortic valve standardized coronary z-scores).
Fetal Echo Z-Scores
Calculate gestational age-adjusted z-scores for fetal echo (left ventricle, mitral valve, aortic valve, aortic arch, etc.) using data published by The Royal Brompton Hospital and Boston Children’s Hospital.
LV Mass Z-Scores
Calculate height-adjusted z-scores of left ventricular mass (m-mode derived calculation) using data published by Montreal Children’s Hospital.
M-Mode Z-Scores
Calculate BSA-adjusted z-scores for common M-Mode measurements (LVEDD, LVESD, IVS, LVPW, LA) using data published by Johannes Gutenberg University, Germany.
TAPSE
Reference values for right ventricular systolic function, using tricuspid annular plane systolic excursion (TAPSE).
Z-Scores of Cardiac Structures: Detroit Data
Calculate BSA-adjusted z-scores of 21 common pediatric echo measurements (m-mode, mitral valve, aortic valve, pulmonary arteries, etc.) using data published by Detroit Children’s Hospital. (Updated 11/2008: added percentiles)
Z-Scores of Cardiac Structures: Wessex Data
Calculate BSA-adjusted z-scores of 15 cardiac structures (mitral valve, aortic valve, pulmonary arteries, etc.) using data published by the Wessex Cardiothoracic Unit, Southampton UK.
