Diagnosis criteria of coronary artery lesions
We use themaximal Z scores from echocardiographicfor evaluationof
the severity of CALs. 13
Z -Score Classification:
1. No involvement: Z scores always <2.
2.Dilation only:Z score ≥2 but <2.5.
3.Small aneurysm (Z score ≥2.5 to <5).
4.Medium aneurysm (Z score ≥5 to <10, andabsolute
dimension <8 mm).
5.Giant aneurysm (Z score ≥10, orabsolute dimension ≥8 mm).
