Aortic Size Index Calculator

Introduction: The Aortic Size Index is a critical parameter in cardiovascular assessment, providing a normalized measure of the aortic diameter based on the individual’s body surface area. Our Aortic Size Index Calculator facilitates this calculation, offering a quick and accurate determination of the Aortic Size Index.

Formula: The Aortic Size Index is calculated by dividing the aortic diameter by the square root of the body surface area. This normalization helps account for variations in body size, providing a more meaningful assessment of aortic size.

How to Use:

  1. Enter the aortic diameter in centimeters.
  2. Input the body surface area in square meters.
  3. Click the “Calculate” button to obtain the Aortic Size Index.
  4. The result will be displayed in the designated field.

Example: Suppose you have an aortic diameter of 4.0 cm and a body surface area of 1.75 m². After entering these values and clicking “Calculate,” the calculator will provide the Aortic Size Index based on the input.


  1. Q: What is the significance of the Aortic Size Index? A: The Aortic Size Index normalizes the aortic diameter based on body surface area, aiding in the assessment of aortic size independent of individual body size.
  2. Q: How is body surface area calculated? A: Body surface area is commonly calculated using established formulas based on height and weight.
  3. Q: What is a normal range for the Aortic Size Index? A: Normal values may vary, but a range around 2.0 is often considered typical. Consult with healthcare professionals for context.
  4. Q: Can the Aortic Size Index be used for pediatric patients? A: Yes, the Aortic Size Index can be applicable in pediatric cases, considering age-appropriate norms.
  5. Q: How often should the Aortic Size Index be monitored? A: Monitoring frequency depends on clinical indications and the presence of cardiovascular conditions. Consult healthcare providers for guidance.

Conclusion: Our Aortic Size Index Calculator offers a valuable tool for healthcare professionals and individuals involved in cardiovascular assessment. By considering both aortic diameter and body surface area, this calculator provides a normalized measure that aids in the comprehensive evaluation of aortic size. Use this tool to enhance cardiovascular risk assessment and monitoring.
