Congenital Heart Disease Support Group
Congenital heart disease is heart disease in the newborn, and includes congenital heart defects, congenital arrythmias, cardiomyopathies, and hypertrophic cardiomyopathy (HCM). CHD can describe a wide variety of different abnormalities affecting the heart. CHD occurs when the heart or blood vessels near the heart does not develop properly before birth.
Bottom line though, research has come so far in the past thirty years. They can do things now that they couldn't five years ago. Hopefully, if a time comes when you must have your valve replaced, maybe they can grow you a new one, or have improved the design further of the mechanicals. I have been a nurse for thirty years and they are doing things now that I would never have dreamed of 5 years ago.
Good luck and Blessings, Diane
