Moderate dilatation; often managed with "aorta-protective" medications like Beta-blockers or ARBs (e.g., Losartan) to lower blood pressure and reduce stress on the aortic wall.
A condition that often requires earlier surgical intervention. aortic root dilatation z score
| Z-Score Range | Clinical Interpretation | Action Threshold | | :--- | :--- | :--- | | | Normal | Routine follow-up | | 2.0 – 3.0 | Mild to moderate dilatation | Annual surveillance; consider genetic testing | | > 3.0 – 4.0 | Moderate to severe dilatation | Increased surveillance (every 6-12 months); pharmacotherapy | | > 4.0 | Severe (Aneurysm) | High risk; consider prophylactic surgery in syndromic patients | consider genetic testing | | >
While powerful, Z-scores are not perfect. Clinicians must be aware of: pharmacotherapy | | >
