We all have our areas of knowledge and thats what makes this place so great. Everyone is here to learn, teach and occasionally throw around a little BS. When it comes to holes in the heart, there are basically two types, the ASD and the VSD. The ASD (atrial septal defect) is pretty common. It results in shunting of blood from the high pressure left side of the heart to the low pressure right side of the heart. The amount of shunting depends on how big the hole is. Tiny is good. Most people with this heart defect do not have any symptoms during early life though some will be physically underdevelped and might be more prone to respiratory infections. The real problems can occur with age. Because you increase the flow of blood into the right side of the heart, this increases the pressure. The heart responds by the muscle increasing in size and thickness in order to deal with the increased pressure and still be able to push blood to the lungs. As these individuals hit their 30's and 40's, there is a tendency to develop an atrial arrythmia. As time goes on the pressure in the right side of the heart approaches equality to the left sided pressure and eventually blood flow across this hole will reverse and non-oxygenated blood from the right side of the heart will begin to flow into the left sided (oxygenated) blood flow. When this occurs, heart failure tends to follow. Of course this is usually on into the late 50's to 70's. If you have this type of defect and are under 40, then evaluation by a cardiologist to see how it has progressed and to see about the potential for repair could extend life expectancy a good bit. This is getting long so I won't discuss the VSD (ventricular septal defect) now. As for your ? Fina, yes most arrythmias come on later in life. Congenital (at birth) arrythmias are pretty rare and tend to be more serious.
