AV canal. If not repaired, eisenmenger syndrome and death occurs.
AV canal. Is an endocardial cushion defect in which there is a deficiency of the septum primum associated with an inlet type of ventricular septal defect. Usually has a cleft left a-v valve. Other concomitant cardiac defects may also be present as well as atrio-ventricular and ventriculo arterial discordance or concordance. Need echocardiogram, cardiac cath, and maybe cardiac MRI as well.
Endocardial cushion. Its a congenital endocardial cushion defect resulting on an inlet type of vsd, a cleft mitral valve, and an ostium primum asd. Fairly common in down's syndrome but may occur spontaneously in non down's.
Yes. If not repaired in a timely fashion, eisenmenger syndrome develops and subsequent death.
No cause. Unless there is trisomy 21 there is no cause for avsd's. Nothing that we know of. You have done nothing wrong during pregnancy.
Unknown. The heart is a very complex organ. We still do not fully understand how the normal heart develops in the fetus. We understand even less about what causes the heart to develop abnormally. It is likely that there are multiple genetic and environmental factors that contribute to abnormal cardiac development.
EKG / Cardiac US. Many vsd's are evident on a good physical exam with characteristic sounds through the stethoscope. A color doppler ultrasound can verify the defect & suggest the amount of flow across the defect. An ekg can show any strain produced on the heart. In some centers a cardiac cath can be done to verify the defect.
ECHO, CATH. Also known as a-v canal vsd:transesophageal echocardiogram, surface echocardiogram, cardiac mra, cardiac catheterization, oxymetry and ventriculography.
Easier method. If it needs to be treated most can be closed with an umbrella like device which is implanted to close the hole. This is done by going through your vein using a catheter, thus avoiding open heart surgery.
It depends. Atrial septal defects (ASD) are generally treated with surgery. However, you would need an evaluation by a cardiologist (heart specialist) and/or a cardiothroacic surgeon (heart surgeon) to determine the best treatment.
Nobody knows. Researchers suspect that down syndromes chromosomal defect (an extra chromosome) may somehow affect the production of proteins used to create connective tissues. The tissue between the pumping chambers of the heart s one particular form of connective tissue.
Chromosomal abnormal. The association of atrial septal defect with Down Syndrome is part of the constellation of body abnormalities that characterize it.
Unknown. The heart is a very complex organ. We still do not fully understand how the normal heart develops in the fetus. We understand even less about what causes the heart to develop abnormally.
It is not known. The cause of avsd is not known. There are known associations, most notably trisomy 21 or down syndrome. Nearly half of the children with avsd have trisomy 21.
Not clear. While avsd is seen associated with trisomy 21 most defects occur spontaneously with no clear cause.
