Defect in a wall. ASD is a hole or window that allows blood to cross between the right atrium (containing oxygen poor blood on its way to the lungs) and the left atrium (containing oxygen rich blood after passing through the lungs, headed for distant organs). Shush! This is privileged information for your eyes only!
Congenital. There are various types of atrial septal defects. The most common is a secundum type. Other types like a ostium primum type, a sinus venosus type, unroofed coronary sinus type, also occur. Other type is a patent foramen ovale. They result in various levels of left to right shunting and right ventricular and pulmonary volume overload. Your pediatric cardiac surgeon can explain your child ASD type.
No. An ASD is a structural malformation of the heart that occurs when the normal sequence of events closing the atrial septum does not finish its work. While an untreated defect may result in a heart related problem (rhythm defect or congestive failure) the defect just makes you more vulnerable to a heart condition.
Yes. Even though "disease" may carry a connotation of "infection" in every day language, in medicine it means that there is some pathology or abnormality.
Yes. In medicine, there's "normal" and there's "disease". Since it isn't normal, by definition, it's a disease. We tend to think of disease as something you "catch" but congenital abnormalities are also diseases. Perhaps you're wondering if it's serious? Depends on size. Some are, some aren't.
Congenital defect. Asd's are congenital heart defects wherein blood is shunted from the left atrium (oxygenated) to the right atrium (deoxygenated) circulations. When this shunt is significant (shunt ratio greater than 1.8) or if there are symptoms of dyspnea or right sided pressure/volume overload (pulmonary hypertension), the asd's should be corrected either surgically or by catheterization techniques.
Yes and no. ASD is considered a congenital heart defect (present at birth). Failure to receive corrective treatment during childhood can lead to secondary heart conditions including rhythm disturbances, or heart dysfunction. It is more a matter of how you define the term.
Sort of. It is considered congenital heart disease as opposed to corornary artery disease.
ASD vs patent ductus. These are not the same thing, an atrial septal defect, or asd, is an opening in the tissue separating the left and right atrium. The ductus arteriosos is a structure present in fetus which allows blood to bypass the lungs and go to the placenta, this usually closes at delivery but can be closed surgically if needed. Often doctors use medications to close it after delivery.
No. ASD is a hole between the upper heart chambers. Patent ductus is a pipe that connects the right heart pump outflow to the aorta, allowing most of the blood to go to the body instead of the lungs (since they are not in use). The PDA is supposed to close when the blood oxygen level increases with breathing. The ASD is just a defect.
What is atrial septal defect? Someone here mentioned it when I asked about low oxygen levels, mine was 89 when they checked it the other day,
See below. Atrial septal defect, as the name implies, is a gap in the wall separating the upper chambers of the heart. You may consult this site for more info: http://www. Mayoclinic. Org/diseases-conditions/atrial-septal-defect/basics/definition/con-20027034.
ASD. An atrial septal defect (ASD) is a communication (hole) in the atrial septum (wall between top two chambers of the heart). It usually results in extra blood flowing through hole from left to right side resulting in eventual enlargement of the right side of the heart. This can take years to decades depending on size of defect. ASD closed with surgery or interventional cardiology (device closure).
Yes. The first successful open heart procedure done on cardiopulmonary bypass was an atrial septal defect repair done by john gibbon in philadelphia in 1953. It is a procedure which has been done for the last 60 years with excellent results. The first atrial septal defect repairs were done off pump with various techniques, including inflow occlusion and hypothermia with circulatory arrest.
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).
