Marfan syndrome with aortic dilation greater than 40 mm is classified as which WHO maternal CV risk group?

Explanation:
In pregnancy, the WHO cardiovascular risk classification sorts maternal risk into levels to guide management. For Marfan syndrome, the big danger is aortic dissection, which becomes much more likely as the aortic root dilates, especially under the to-and-fro hemodynamic stresses of pregnancy and delivery. A root diameter greater than 40 mm indicates a high-risk situation where the chance of catastrophe is substantial. That level of risk places the patient in the highest category, where pregnancy is considered contraindicated or must be managed only in a specialized center with a multidisciplinary team and intensive monitoring. So, this scenario is categorized in the most cautionary group.
