Marfan syndrome affects the connective tissue. It can cause problems in many parts of the body, including your joints, bones, eyes, heart and blood vessels. If you have Marfan syndrome and are considering pregnancy, it is very important to talk to your doctor. The condition and treatments increase the chance of problems for both you and your unborn baby.

Pregnancy creates extra stress on the heart and blood vessels. The biggest concern for patients with Marfan syndrome is serious complications of the aorta, such as a tear or rupture that can cause death or serious injury to both you and your unborn baby. The risk is greatest if your aorta is dilated more than 4 cm. If this is the case, you should wait to become pregnant until after you have surgery to repair your aorta.
