The choice of imaging depends on the situation, the patient, and the team’s skills. These methods help doctors get precise measurements of the aortic root. This is vital for making treatment plans and tracking the disease.
Aortic Root Normalisation and Indexing
To make sure the aortic root size fits the patient, it’s often adjusted. This is done by comparing it to the patient’s body size or height. This way, the size of the aortic root is looked at in relation to the patient’s size. This gives a clearer picture of how the aortic root fits the patient.
Adjusting for Body Surface Area and Height
The aortic root index by body surface area and the aortic root index by height are used to standardise the aortic root size. These methods help doctors see if the aortic root fits the patient’s size well. They look beyond just the aortic root’s size.
- The aortic root index by body surface area is found by dividing the aortic root diameter by the body surface area. It’s usually in centimetres per square metre (cm/m²).
- The aortic root index by height is worked out by dividing the aortic root diameter by the height. This is often in centimetres per metre (cm/m).
These methods help with aortic root normalisation and aortic root indexing. They make it easier to see how the aortic root size relates to the patient’s body size.
| Normalisation Method | Formula | Interpretation |
|---|---|---|
| Aortic Root Index by Body Surface Area | Aortic Root Diameter / Body Surface Area | Provides a measure of aortic root size relative to the patient’s body size |
| Aortic Root Index by Height | Aortic Root Diameter / Height | Evaluates the aortic root size in the context of the patient’s stature |
“Adjusting the aortic root diameter for body size is crucial in accurately assessing the proportions of the aortic root and identifying potential abnormalities.”
By adjusting aortic root for body size, doctors can better understand the patient’s aortic root health. This helps them make better decisions about what tests or treatments are needed.
Aortic Root Size Index Calculation and Formulas

Aortic Root Z-Score and Risk Stratification
The aortic root z-score compares your aortic root size to what’s expected for your age, sex, and size. It helps doctors decide on treatments and how much risk you might face. This score is key for sorting out if your aortic root size is normal, just a bit off, or way off.
Understanding Z-Score Values and Clinical Implications
A z-score shows how far your measurement is from the average. For aortic roots, a score of 0 means it’s just right. Scores above or below mean it’s bigger or smaller than usual.
- A z-score of less than 2 is considered within the normal range.
- A z-score between 2 and 3 indicates a borderline or mildly dilated aortic root.
- A z-score greater than 3 signifies a significantly dilated aortic root, which is associated with an increased risk of adverse cardiovascular events, such as aortic dissection or rupture.
Doctors use z-scores to decide on treatments, keep an eye on how the disease is progressing, and when to act. If your score is high, you might need more check-ups and possibly surgery to prevent problems.
| Z-Score Range | Interpretation | Clinical Implications |
|---|---|---|
| Less than 2 | Normal | Routine follow-up and monitoring |
| 2 to 3 | Borderline or mildly dilated | Increased surveillance, potential medical therapy |
