How bad is an atrial septal defect?

How bad is an atrial septal defect?

ASD: It is variable, depending on the size of the opening and the amount of blood traveling across it. Sometimes they are diagnosed in childhood, others are picked up in adults. They are closed if the size is significant either surgically or using catheters. But if they are small they can be followed and monitored with echocardiograms. ...Read more

What's it mean to have atrial septal defect?

What's it mean to have atrial septal defect?

Depends...: Depends on the size and the amount of blood it is allowing to leak from the left to the right heart chambers which in turn causes strain on the right heart. This can cause shortness of breath and arrhythmias. Patient with medium size defects may not have any problems until their middle age and patients with smaller defects can lead a full healthy life without even knowing it. ...Read more

What are the tests for atrial septal defect?

What are the tests for atrial septal defect?

Echocardiogram: Echocardiogram is an ultrasound of the heart that can see if there is a hole between the 2 upper chambers of the heart (atrial septal defect). A cardiac catherization can also determine if ASD exist, but is invasive. ...Read more

What are the symptoms of atrial septal defect?

What are the symptoms of atrial septal defect?

Shortness of breath.: Many asds are asymptomatic, but when patients have symptoms, it's usually shortness of breath and exercise intolerance. If the ASD has been present for many years, it may cause an abnormal heart rhythm as well as lung injury. ...Read more

What sort of problem is an atrial septal defect?

What sort of problem is an atrial septal defect?

ASD: ASD is a congenital (present since birth) heart defect in which the wall that separates the 2 upper chambers (atria) is perforated allowing the abnormal mixing of oxygenated and un-oxygenated blood. If large enough, it can lead to rhythm disturbances and heart failure but if small, no treatment is necessary. Echo and MRI are very accurate in assessing the severity. It is correctable/curable. ...Read more

What are the symptoms of an atrial septal defect?

What are the symptoms of an atrial septal defect?

It depends: Atrial septal defects (asd's)can vary in size and location. The small asd's can be without symptoms and can go undiscovered for many years. Other symptoms include shortness of breath, fatigue, abnormal rhythms, heart failure and low oxygen levels. Strokes can occur from small clots in leg veins crossing to left side and going to brain. Some reports that migraine headaches are caused by asd's. ...Read more

What is a secundum atrial septal defect?

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 more

Is ventricular or atrial septal defect hereditary?

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 more

Hello docs, is asd (atrial septal defect) hereditary?

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
