Reference charts

Aortic diameter by height

Growth-chart style curves for each level of the aorta, with the z-score bands used by the calculator. Add a child's visits to follow them over time.

Curves show the median and z = −2, +2, +3.5 and +5 for a child of typical build (height-and-sex model). Shading follows the calculator's bands. Hover the chart to read values at any height.

Visits

Example visits are shown: a boy followed from 6 to 10 years. Edit them, clear them, or add your own. Entries stay in this browser only.

Results use the sex selected above. When a weight is entered, z and percent of expected come from the full model (height, weight for height, age and sex), so a point can sit slightly differently from the typical-build curves. Percent of expected is the steadier number to follow when a diameter is far outside the normal range.
