mom1967 please E-Mail me at ***@**** I need to tell you something about your condition.
I would check in your area for a regional medical center that has a Children's Hospital with a pediatric cardiology department as they will specialize in rare and congential heart defects that adult cardiologist do not see very often.
Hello,
I am sorry to heart about your family medical problems. Anyone in your situation would be nervous -- it is human nature.
Unfortuately I am an adult cardiologist and just don't know alot about congenital heart diseease, in fact, I have never seen a case of hypoplastic left heart syndrome (HLHS).
It is possible to have a isolated cleft mitral valve. You are also correct that a cleft mitral valve is associated with atrioventricular septal defect (partial AVSD includes only a primum atrial septial defect and complete AVSD includes a ASD and ventricular septal defect).
To answer your question directly, it IS possible to have a normal fetus with a cleft mitral valve and a partial or complete AVSD. It does not mean that they will have downs syndrome. I agree that you should see someone who specializes in this though, especially if you are not satisfied that your ob/gyn is answering your questions.
This is a very complicated situation and I wish you all the best, physical and emotional, for the remainder of your pregnancy.
