• Free Online Ascending aorta Z-score Calculator

There are two data sources used for this giving you two calculators

1. Halifax (Heart, 2006)
2. Paris (AJC, 2010)

1. Halifax (Heart, 2006)

Calculate Z-Scores of the ascending aorta and aortic root using data published in 2006 from Halifax, Nova Scotia. Per the authors: “Measurements were made in systole… in the parasternal long axis… from inner edge to inner edge. The ascending aorta was measured at the level of the right pulmonary artery.”

2. Aortic Root Z-Scores (Gautier et al, Paris, AJC-2010)

Z-scores of the aortic root at the level of the aortic annulus, sinuses of Valsalva, sinotubular junction, and ascending aorta. Measurements are from the parasternal long axis: aortic annulus measured in systole at the hinge points of the leaflets; sinuses, sinotubular junction and ascending aorta are measured in diastole using leading-edge to leading-edge technique. Data is from 353 normal children as reported by investigators at Hôpital Bichat, Paris, France.
