A hole in the heart is almost always congenital...it is a hole between chambers (right and left). Worst case scenario would be an operation and a patch to cover the hole. If it is small, it should be watched and is insignificant for a medical problem.
Hey Tiffy,
I am 35yo and just had open heart for an ASD. This is a hole in the wall between the two top chambers of your heart. A lot of people have these things and are very healthy, I was given the example of Kerry Wood the Cubs pitcher has the same thing and if fine. In my case I had a small stroke (TIA) this past summer so my doctors and my self decided to have it closed. Normally they do this with a patch. It is an out patient thing so you do not stay in the hospital. I keep a positive attitude and take these things one step at a time.
Hope this helped.
