Aortic Valve Leak and Aneurysm: Day 3
Do You Have a Dilated Aorta? Assess Your Risk Here.

Did you know that your height and weight could help predict your risk of aortic complications in aortic dilatation? Discover how we use cutting-edge nomograms to tailor your cardiac care.

Imagine a map where your body size meets your aortic dimensions. This ‘map’ is actually a nomogram – a powerful tool we use to calculate your individual risk. It’s not just about the size of your aorta; your body surface area plays a crucial role too.

Here’s how it works: We start by calculating your body surface area using your height and weight. Then, we measure the largest dimension of your aortic root or ascending aorta using a contrast CT scan. These two pieces of information allow us to plot your unique position on our nomogram.

This approach offers several key benefits:

1. Personalised risk assessment: The nomogram accounts for individual body size, providing a more accurate risk profile.

2. Simplified decision-making: The colour-coded risk zones (green for low, yellow for moderate, light brown for high, and red for severe) offer clear guidance.

3. Early intervention opportunities: By understanding your yearly risk, we can make informed decisions about when intervention might be necessary.

For example, a patient with a body surface area of 2 (roughly 180 cm tall and 80 kg) would be at moderate risk with an aortic dimension between 4.5 and 5.5 cm, and at high risk at 6 cm.

Interestingly, research has shown that height alone can be a good predictor of risk, simplifying the process for quick assessments. However, for the most accurate results, we always use the full calculation in our clinical decision-making.

Understanding your aortic risk is a crucial step in managing your heart health.
