Z-Score Calculator

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)

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.

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.

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 Z-Scores

By Justin

Use this free TAPSE Z scores calculator to obtain reference values for right ventricular systolic function using the tricuspid annular plane systolic excursion (TAPSE) measurements. Data are from 640 patients, aged 1 day to 18 years, as described by investigators in Graz, Austria. TAPSE was measured by “2-dimensional echocardiography–guided M-mode recordings from the apical 4-chamber view, with the cursor placed at the free wall of the tricuspid annulus.”

M-Mode Z-Scores

By Justin

Use this M-Mode Z scores calculator to obtain normal values of M-mode measurements made in Echocardiography. Normal values of M mode echocardiographic measurements of more than 2000 healthy infants and children in central Europe were used as reference and data source for this tool.
