What causes non-innocent heart murmurs in children?
-
Dr. Mohamed Djelmami-Hani of Aurora Health Care answered:A "noninnocent" heart murmur can be caused by an abnormal structure in the heart or in the heart's blood vessels or valves. Examples of these would be a "hole in the heart," a leaking heart valve, or a heart valve that is smaller than normal.
