Never assess aortic root size without calculating the Z-score. The internal diameter of the aortic root (usually

Relying solely on absolute aortic diameters (e.g., >40 mm) is misleading. A 38 mm aortic root in a 6’5’’ male basketball player is likely normal, whereas the same 38 mm root in a small-statured 55-year-old woman may represent significant aneurysmal disease. The Z-score adjusts for , age, and sex, allowing for a fair, individualized assessment.

Current guidelines define aortic root dilatation based on Z-score thresholds:
