Yes, it does. The congenital heart problem is always there although it can often be made much better as a result of surgery or treatment with a catheter based therapy. Many children born with heart problems live to be active, normally functioning adults, and there are some heart conditions that people are born with that are so well tolerated that sometimes they are not even discovered until the person is a young adult or even elderly. That depends on the problem. Sometimes the treatment is nothing.
Nothing needs to be done.
Sometimes the treatment is surgery. Sometimes this requires more than one operation. Newer treatments have become available in recent years and can be done without surgery. For example, some holes in the heart can be closed with special devices placed under local anesthesia using x-rays to guide the placement. For example, placing a coil to plug the vessel without doing surgery can close some abnormal blood vessels.
