Congenital heart disease: overview
Contributor(s): Peter Darke, Daniel Schrope, Mark Oyama
- Congenital heart defects (CHDs), may be defined as those abnormalities of heart structure that are present at birth.
- 'Congenital defect' is not synonomous with 'genetic defect' since other causes such as toxin or viral exposure must be considered.
- Traditionally, abnormalities of aortic arch development are also included in this category of cardiac disease.
- Many congenital cardiac defects arise as a result of the aberrant embryological development of the heart and great vessels.
- Canine congenital heart defects include:
