# Pediatric and Fetal Echo Z-Score Calculators

Using the medical literature and published data to generate z-scores and reference values (normal values) for pediatric and fetal echocardiography

- WWW!
- Announcing a new parameterz.com site with new references! All development has moved over to this new platform and I will no longer be developing for this site (Blogger). That's a good thing.

- App
- The ParameterZ web app. A lot of information in a little package. Log in with your Google account.
- 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).

Also see: consolidated aortic root z-score calculator - 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 HÃ´pital 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). Also, have a look at my comparison and charting tool.
- 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.
- LVEDV Z-Scores
- BSA-adjusted z-scores for LVEDV in patients < 3 y.o. using the 5/6 Area Length (Bullet) formula. (sorry about the offsite link- I'm trying something different)
- 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.
