Block 2
History of Marfan’s Syndrome
• The disorder was first logged as a medical
condition called arachnodacryly in 1896 by
Antonie Marfan.
• His findings however, had been suggested 20
years earlier by a doctor in Ohio.
• It was named arachnodacryly, from the Greek
word for “spider”, arachne because of the long
digits of those with Marfans.
• Today, the National Marfan Foundation is
leading research.
• Anyone can be affected.
Diagnosis
• Scientists have discovered what mutation
causes Marfan Syndrome (MFS)
• However, a genetic test alone can’t tell
determine if you have MFS or not.
• So, diagnosis is made through a clinical
evaluation such as an arm span greater
than height.
• There are certain diagnostic criteria that
are compared to a persons test results,
history and physical examination.
Diagnosis (Cont.)
Transmission
• MFS is caused by a mutation
in the gene that tells the body
how to make fibrillin-1.
• This results in an increase in a
protein that causes problems
in the connective tissue
throughout the body.
• People most commonly inherit
MFS but 1 in 4 have a
spontaneous mutation.
• There is a 50% chance of
passing on MFS
Signs and Symptoms
Heart and Blood
Vessels (Cardiovascular system)
• Enlarged or bulging aorta, the main
blood vessel that carries blood from
the heart (aortic dilation or
aneurysm)
• Separation of the layers of the aorta
that can cause it to tear (aortic
dissection)
• “Floppy” mitral valve (mitral valve
prolapse – MVP)
Bones and Joints (Skeletal system)
• Long arms and legs
• Tall and thin body type
• Curvature of the spine (scoliosis or
kyphosis)
• Chest sinks in (pectus excavatum) or
sticks out/pigeon breast (pectus
carinatum)
• Long, thin fingers
•Flexible joints
•Flat feet
•Teeth that are too crowded
Eyes (Ocular system)
•Severe nearsightedness (myopia)
•Dislocated lens of the eye
•Detached retina
•Early glaucoma
•Early cataracts
Other Body Systems
•Stretch marks on the skin, not
explained by pregnancy or weight gain
•Sudden collapse of the lung
(spontaneous pneumothorax)
•Swelling of the sac around the spinal
column (dural ectasia). This is found
with CT or MRI scans of the back
(National Marfan Foundation, 2010)
Treatment
1.
Heart-Valve-Sparing Surgery-Part of the aorta is taken
out and replaced with a woven tube but the persons
aortic valve is left in place and attached to the tube.
Advantages
•
Do not need to take blood thinning medication.
•
No risk of forming clots
•
Fewer concerns about becoming pregnant
Disadvantages
•
Newer procedure and less experience
•
Not available in all parts of the country
•
Not an option for everyone.
Treatment (Cont.)
2.
Scoliosis- Spinal Surgery – Needed because of
abnormally loose ligaments of the spine. Surgery
involves straightening the spine and fusing it in place.
Advantages
•
Usually Successful
•
Patient can transfer own blood
Disadvantages
•
Rods can come loose
•
Nerve damage
Treatment (Cont.)
3.
Eye Surgery – Lens Removal - Usually needed for lens
dislocation, progressive cataracts, and uncorrectable
vision.
Advantages
•
Help balance pressures in the eye
•
Prevent permanent blindness
Disadvantages
•
Raises the risk of retinal detachment
•
Risky and technically difficult
