People with atrial septal defect murmur. When is it dangerous to you?

Good question. Atrial septal defects are holes in the wall separating the right and left atria. If the holes are very tiny, they may heal completely and disappear. If the holes are small, they may continue to exist, but may be harmless long-term. Large atrial septal defects can cause heart failure in the long term and often need surgical repair to prevent premature death.
Stroke and infection. Because of an initial left-to-right shunt, increased volume and pressure in the pulmonary circuit lead to pulmonary hypertension and eventual right-to-left shunt. Clot and infection may originate at this abnormal septal defect that may travel from the heart to the brain causing stroke.

Abnormal shunt left to right atrium suggestive small atrial septal defect can this make the shunt also go right to left if so is it dangerous?

Pressure gradient. Blood will flow across a hole in the heart from the higher pressure left to the lower pressure right. If the pressure on the right increases it can become higher than the left, then flow will reverse. That is not a good thing. Most ASD are insignificant. Read more...
If RA>LA pressure. Shunt flow will direct from the higher pressure chamber to the lower pressure one. This usually results in left to right shunting across an asd. Over time, as flow into RA is increased, a corresponding increase in pulmonary blood flow will lead to pulmonary hypertension. The subsequent rise in right sided pressures will lead to reverse shunting (r to l) with cyanosis (eisenmenger). Read more...
Possibly. Any right to left shunt has the potential to be dangerous by allowing a blood clot to cross through the heart and go out to the body--and potentially cause a stroke. However, many people have asds and do not have this problem. Please provide more info or discuss your specific risks with your cardiologist. Read more...

In general, exercise is a good thing. But again, please discuss your specific risks with your doctor before starting an exercise regimen. Read more...

What does it mean if my child has atrial septal defect?

Atrial septal defect. 4 types. Ostium primum, ostium secundum, sinus venosus asd, patent foramen ovale. Ostium primum and sinus venosus require open heart repair. Secundum, depending on size may be amenable to clamshell device vs open heart surgery repair. Pfo most amenable to endovascular repair. Diagnosed by echocardiogram, cardiac cath. Shunt fraction, arrythmias, reversibility of pulmonary hypertension all important. Read more...
Hole in wall. You have 2 upper chambers in the heart & 2 lower.An atrial septal defect is a hole in the wall between the upper chambers. It is under less pressure than the lower chambers so it often causes no obvious problems early on. Most are closed using various methods before school age. Read more...

Two choices. Depending upon the characteristics of the defect; there are 2 ways to close an atrial septal defect. The traditional approach has been surgery with a success rate of nearly 100%; however there is a risk of arrhythmia and effusion. More recently, catheter delivered closure devices have been used for select patients.. The overall success rate is about 98% and the risk of complications is lower. Read more...

Often none. Even patients with large asds often have no symptoms until later in life. Some young children with large asds get respiratory infections more commonly. As patients age, they can have symptoms of right heart failure (decreased energy, large liver, swollen ankles), rhythm abnormalities or cyanosis (turning blue from not enough blood getting to the lungs). We try to treat asds before symptoms develop. Read more...
