title: Why does a child with a normal heart undergo cardiac catheterization?
abstract: Children who have no heart disease at cardiac catheterization have usually been referred because of signs or symptoms on the background of a basal flow murmur. The ECG and chest x-ray are sometimes spurious and may lead to catheterization. Advances in noninvasive testing are helping to screen this population. Only in rare instances should the risks involved with catheterization be taken in a child with a basal flow murmur and no other evidence of heart disease.
