'''Introduction'''

Congenital heart disorders are structural and/or functional abnormalities that are present at birth. These defects are the result of either inherited abnormalities or insults to the fetus in utero.  The most common conditions are listed below.

Congenital abnormalities occur relatively commonly in young (approximately 1% all human births).  May produce dramatic clinical signs or signs may be vague, such as failure to thrive.  Clinical signs may become more apparent as the animal grows and activity levels increase.
