Enlarged heart / marfens syndrome
My son is 21, he was dignoised with marfens syndrone after a bad accident at the age of 16. His pedractric dr. was watching him and his sister when they were toddlers, then retired so I heard nothing more about marfens until the accident. At 17 his lung collasped 3 times, they ended up having to take a small part of his lung out. He has large hands and fingers, large feet and toes, very tall 6' 5 1/2" tall, very skinny. He was just given a physical/drug test from his employer, they notised problems with heart rate, blood pressure etc. he was dent to his doctor for some tests, I know there was a blood test plus a few others. He was told by the doctor he didn't have marfens syndrome, he was healthy except he has an enlarged heart. Then told not to worry about it.
Question-- should we get another opinion from another doctor?
Should we worry about an enlarged heart?
I'm not sure what to do please help, I have 2 kids both were told they have marfens so I'm not sure what to think.
Also his dads family has marfens syndrome in there family.
