Echo report, MVP

  I just got the echo results on my daughter.  The
  cardiologist said she has mitral valve prolapse with trivial regurgitation.  I noticed that her left ventricle is larger than normal but he says it's ok.
  The report says: Trivial mitral regurgitation, no stenosis, mild holo-systolic prolapse noted.  The leaflets are thick and elongated.  Trivial tricuspid and pulmonic regurgitation.
  An echo she had 2 1/2 years ago was reported as normal.
  She has what the cardiologist thought was a wide split second sound and he calls it a click instead and a diastolic murmur and systolic.
  The numbers on the echo says:  LVIDD 5.4 (3.6-5.2cm) LA 3.6 (2.1-3.7)  I really worry about the LVIDD and why it's large.
  Ejection fraction is 62%
  Cardiac output 5.21
  Cardiac index 2.93
  Stroke volume 86.9
  I don't have her holter monitor report but he said her only problem was sinus tachycardia (which was my concern initially as well as her frequent fainting and near fainting)
  Is this ventricle size really "normal" for a 13 year old girl?  And also would you mind commenting on the type of MVP that she has..is it ok for her to participate in sports?
  PS... our family has a chromosome 11 abnormality (pericentric inversion) but still being studied at NIH.  The primary problem is overgrowth resembling gigantism and acromegaly in the men and tall woman with premature puberty.  My brother was 7'2" tall and died at the age of 28.. probably due to the morphine he was given in the hospital for pneumonia and obstructive sleep apnea "at 2am he had a pulse, at 3am he didn't".  He wasn't on a cardiac monitor since his pneumonia wasn't that bad.
  Sorry this was so long!!

Dear Chris,
Your daughter's echocardiogram report makes a finding of MVP.  As in this case, mitral valve prolapse is commonly due to a redundancy and thickening of the leaflets of the mitral valve.  These thickened, somewhat floppy leaflets sometimes result in the presence of significant mitral regurgitation(MR). Overall, the prognosis for mitral valve prolapse is excellent.  In certain cases, such as significant MR or severely thickened leaflets, antibiotic prophylaxis is recommended prior to dental and other procedures that might increase the risk for infection of the heart valves (bacterial endocarditis).  I do not think that the dizzy spells and fainting are related to your daughter's MVP.  Also, the MVP alone should not influence her decision to participate in sports.
