Calculate Aortic Root Index



Formula

The formula to calculate the Aortic Root Index is:

\[ ARI = \frac{\text{Aortic Root Diameter (cm)}}{\text{BSA (m²)}} \]

Where:

Example

Let's say the Aortic Root Diameter is 3.5 cm and the Body Surface Area is 1.8 m². The Aortic Root Index would be calculated as follows:

\[ ARI = \frac{3.5}{1.8} \approx 1.94 \text{ cm/m²} \]

So, the Aortic Root Index is approximately 1.94 cm/m².

What is an Aortic Root Index?

The Aortic Root Index is a medical measurement used to assess the size of the aortic root in relation to the patient's body surface area. This index is particularly useful in detecting conditions such as aortic root dilation, which can lead to serious complications like aortic dissection or rupture. The Aortic Root Index is calculated by dividing the diameter of the aortic root by the patient's body surface area, and the result is expressed in cm/m².

Aortic Size Index Calculator

Definition: The aortic size index is calculated to assess the size of the aorta relative to body surface area.

Formula: \( \text{ASI} = \frac{\text{Aortic Diameter}}{\text{Body Surface Area}} \)

Example: \( \text{ASI} = \frac{4.5}{1.8} \)

Aortic Height Index Calculator

Definition: The aortic height index is used to normalize the aortic diameter to the height of the individual.

Formula: \( \text{AHI} = \frac{\text{Aortic Diameter}}{\text{Height}} \)

Example: \( \text{AHI} = \frac{4.5}{170} \)
