Atrial Spetal Defect
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. ...Read moreSee 1 more doctor answer
ASD: An atrial septal defect is a common congenital geart defect. It is a hole in the atrial septum - the wall between the left and right atrium. This lets blood flow from the left into right atrium (usually). If not caught at an early age, it results in excessive blood to right side of heart and lungs. Fixed with surgery (sutyred closed) or with a umbrella like device via cath. ...Read moreSee 5 more doctor answers
Two ways: A large vsd with increased pulmonary blood flow may cause a diastolic flow rumble caused by a large amount of flow coming back from the lungs across the mitral valve into the left ventricle. Perimembranous and supracristal vsds can cause aortic valve deformation, and subsequent development of a diastolic murmur of aortic valve insufficiency. ...Read more
Holosystolic: Classically, a vsd results in increased blood flow from left to right ventricle due to pressure differences and results in a holosystolic murmur. Several situations where a diastolic murmur may be heard is 1) large vsd results in aortic cusp sucking into vsd and aortic regurg, 2) very large defect with so much flow to lungs and back to left side with diastolic rumble through mitral valve. ...Read moreSee 1 more doctor answer
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. ...Read more
Not typical: The classic VSD physical finding is of course a holosystolic murmur. However, if the VSD is subarterial or supracristal, it can distort the aortic valve, sometimes causing leaflet prolapse. If this results in significant aortic insufficiency, there will be an associated diastolic murmur (with the insufficiency representing an indication for surgical repair). ...Read more
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). ...Read more
Is a PFO the same as atrial septal defect? Echo states abnormal shunt suggestive small atrial septal defect.What does suggestive mean is it def small?
Unfinished formation: The heart develops originally from a long tube that folds on itself in the embryo & forms the main chambers & features. The walls between the chambers are outgrowths that come together. If the walls did not completely form a gap will exist.In the upper chamber if a gap is left the atrial septal defect is "unfinished formation". ...Read more
Does atrial septal defect (asd) or ventricular septal defect (vsd) occur in some population groups more than others?
Yes: ASD is more common in females 2-3/1, while vsd is only slightly more common. A variety of heart defects are frequently seen in chromasome defects, trisomies, deletions etc. Some asian populations have a form of vsd at higher frequency. There are polygenic factors that increase risk within families with heart defects for offspring with a lesion. ...Read moreSee 1 more doctor answer
