Marfan syndrome is an inherited disorder that affects connective tissue — the fibers that support and anchor your organs and other structures in your body. Marfan syndrome most commonly affects the heart, eyes, blood vessels and skeleton.
People with Marfan syndrome are usually tall and thin with disproportionately long arms, legs, fingers and toes. The damage caused by Marfan syndrome can be mild or severe. If your aorta — the large blood vessel that carries blood from your heart to the rest of your body — is affected, the condition can become life-threatening.
Treatment usually includes medications to keep your blood pressure low to reduce the strain on your aorta. Regular monitoring to check for damage progression is vital. Many people with Marfan syndrome eventually require preventive surgery to repair the aorta.
