The Cardio Z App calculates z-scores for many aortic measurements. The include the aortic valve, sinuses, sino-tubular junction, ascending aorta, aortic arch, aortic isthmus and aorta at the diaphragm. The full range of reference points available is dependent upon the selected refrerence data.
Aorta z-scores derived from the data of Pettersen et al (2008) (‘Detroit’)
Aorta z-scores derived from the data of Warren et al (2006) (‘Halifax’)
Aorta z-scores derived from the data of Gautier et al (2010) (‘Paris’)
Aorta z-scores derived from the data of Daubeney et al (1999) (‘Wessex’)
Correction measurement points, both in terms of 2D caliper position and timing within the cardiac cycle, is critical for correct application of these z-scores. Diagrams and information are instantly available.
