Maybe. If your grandparents, or parents did not have ASD it is unlikely. Asds have a natural non genetic occurrence.
Not completely. The genetic influence of congenital heart defects travels on several different genes & there is some risk for first degree relatives (offspring, sibs). The risk for offspring to have some heart defect (not the same) runs ~4% while it jumps to 6-8% if both parents have some form of defect. Of some interest, there is a basic 4% risk of some unexpected outcome for any pregnancy. (defect, premi, illness).
Sometimes. Sometimes it is hereditary.
Yes, but complex. There is a hereditary component to atrial septal defects. Some patients with known genetic syndromes have ASDs as well. In most cases though, the mechanism of heritability is complex. Please discuss these issues with your physician to determine your specific risks.
Multiple genes. The information needed to code for normal formation of the heart travels in many genes. There is a linkage to other forms of congenital heard defect. Someone with an ASD will have a 4% risk of having a kid with some form of chd, not necessarily the same one.
Possibly. While there are some reports of familial clusters, generally it is a congenital condition affecting caused by a developmental defect.
There is. A higher likelihood of an ASD in a sibling or a child of a mom with add so yes, there is a genetic component.
Depends. Can be familial......... More frequent in the family tree.
Yes (in a sense) We are only just beginning to understand the genetics of congenital heart disease (chd). There are some specific genetic syndrome associated with asds. In addition, simply having an ASD does impart an increased risk--though small--of having children with chd. So yes, having chd is heritable, but in a multifactorial way (i.e. Not a single gene defect in many cases).
Most cases no. The chances of being born with a heart defect are approximately 8 per every thousand deliveries (a little under 1%). Most babies born with a heart defect (asd, vsd or any of a multitude of others) have no family members with heart disease. Now, when there is a first line family member with a heart defect the chances increase to about 2-3%, so there may be some genetic component.
Polygenic influence. The congenital heart defects are influenced by multiple genes on various separate chromosomes. Except for a few known to come up in specific autosomal dominant/recessive syndromes, most have minimal transmission risk. Inheritance of any chd from an affected parent is quoted at 4% for any chd (not necessarily the same one).If a parent with a chd has a child with a chd risk increases for the next pg.
In some cases. Some cases of atrial septal defect have a genetic component. An example is holt-oram syndrome which is caused by a mutation in the tbx5 gene. Tbx5 codes for a protein called t-box 5, which is a transcription factor active during fetal development and is important in the proper development of the heart and the upper extremities. Almost certainly, there are other important genes.
I had my atrial septal defect repaired over a week ago through my groin. When can I begin to smoke again?
Whenever. You are old enough to know better, but if you want to smoke, knock yourself out. Start anytime you want to.
What to do if I had my atrial septal defect repaired over a week ago through my groin. When can I start to smoking again?
Now. You are an adult. Smoking is your choice. If you understand the risks, and still choose to smoke, good luck. Just don't claim addiction, bad genes, or that the Boogey Man made you do it.
Had open heart surgery for my atrial septal defect 3 years ago. Everyday since then my heart skips a beat at least once a day, is this normal?
Yes. Relax dont worry.
Maybe and maybe not. Depends on whether anything else is going on; i.e. Any symptoms, passing out, chest pain, cough? Any changes on your ecg? A few "early" heart beats can be normal, but a cardiologist would have to ensure nothing else bad was happening and evaluate an ecg. Bring this to the attention of your cardiologist, but it is not immediately worrisome in the absence of significant symptoms.
