Marfan Syndrome Z Score -

The Z-score works alongside the , which evaluates physical traits across the body. A diagnosis is often confirmed if a patient has an aortic Z-score ≥ 2.0 plus a Systemic Score ≥ 7 points . Key features contributing to that systemic score include:

Raw diameter measurements are often misleading. For example, an aortic root diameter of 35 mm might be considered "mildly dilated" in a tall adult but represents severe dilation in a small child or a young female. Without indexing to body size, clinicians risk under-diagnosing small individuals and over-diagnosing large individuals. marfan syndrome z score
