How hard is it to diagnose? Hypoplastic left heart syndrome during? Pregnancy?

Tricky. Hlhs should be blatantly obvious in the third trimester, if one looks. However, most fetal anatomical surveys are performed at 18-21 weeks, and the full picture of this syndrome may not be esily appreciable at that early point in fetal development. So, in direct answer to your question, hlhs can be missed in over half the cases, unless a late third trimester cardiac evaluation is performed.

Is it possible? For a baby to survive with? Hypoplastic left heart syndrome?

Sure! The perinatal mortality and infant mortality with hlhs is at least 30%, even in the best centers of congenital heart defects. It is uniformly lethal if undiagnosed/untreated. See: http://texaschildrens.Org/locate/doctors/ayres, -nancy/. Read more...

What are the chances of having more then one child with hypoplastic left heart syndrome?

2-6% with 1-2 sibs. Multifactorial inheritance usually is quoted for hlhs, with a 2% recurrence risk if one prior affected sibling and a 6% recurrence risk with two prior affected siblings. Rarely an autosomal recessive form can be seen with 25% recurrence risk from the same parents. Read more...
Tiny. The genetic influences on heart formation/defects are complex and located on several separate chromosomes.The risk of you having another kid with ANY heart defect (there are lots of them) is about 4%, while that of the same defect is incredibly small. Read more...

Which other surgeries may be performed on a child with hypoplastic left heart syndrome?

HLHS Surgeries. Norwood (stage i) glenn (stage ii) fontan (stage iii) some programs may do a hybrid version of stage i, called the "hybrid stage i". Occasional patients with hlhs will need other procedures depending on their anatomy, but those 3 are the standard surgical treatments. Read more...
See below. There are usually a series of operations that are performed on these children to improve blood flow throughout the body.

Is Surgery treatment for Hypoplastic left heart syndrome effective? Drs here (Jordan) said that the surgery can only give the child few extra days?

Complex. Surgery needs to be performed in a highly specialized center for cardiac surgery, it is a complex surgery involving several stages, or ultimately a heart transplant, either way, life long follow up is needed, so unless the funds and other support means are available, as social/emotional support, life won't be easy for the child or the family, good luck.

What age can some 1 live 2 with hypoplastic left heart syndrome?

Tough to say. I've seen patients live into their 20's with hlhs, but it is hard to imagine how different things will be 20 years from now. An excellent surgeon is a crucial factor. Read more...
Unknown. The operation for this problem has been around since the late 70's. But long term survivors are still not that frequent. It is fair to say that a normal life span is probably not going to happen. Getting to age 30 or 40 may be the best, most optomistic prediction without a heart transplant, which is likely next option. However, some patients, even though few, will likely live longer. Read more...

How does anyone know someone has hypoplastic left heart syndrome?

Echocardiogram. An infant will be suspected as having heart defect by examination and pulse oximetry. A pediatric cardiologist will perform an echocardiogram to make the diagnosis. The infant may appear very normal on the outside. Once changes occur in the newborn infant hlhs is not compatible with life without surgical intervention. A fetal echo by an experienced ped cardiologist can id this before birth. Read more...

Is it possible to have more than 1 child with hypoplastic left heart syndrome?

Genetic components. Hypoplastic left heart syndrome, in some cases, appears to have a familial (genetic) component. There are various genes that have been suggested to have influence over cardiac development where mutations in one of those genes may result in hlhs. Additionally, there are families where bicuspid aortic valve and hlhs (and other left-sided obstructive lesions) have related inheritance. Read more...
