Causes and Types of Cyanotic Heart Disease
The exact cause of CCHD is still unknown, but experts believe it’s linked to genetics and abnormal chromosomes. Other contributing factors include illnesses of the mother during pregnancy, such as phenylketonuria, diabetes, or a viral infection. Drug use may also increase the risk for cyanotic heart disease.
Like mentioned earlier, CCHD refers to a group of heart defects. These heart defects can be categorized into:
Left Heart Obstructive Lesions
Defects under this category affect the blood flow between the heart and the rest of the body (systemic flow). Specific conditions include Interrupted Aortic Arch and Hypoplastic Left Heart Syndrome.
Right Heart Obstructive Lesions
This affects the blood flow between the lungs and heart (pulmonary flow). A condition under this category is Tetralogy of Fallot, which is the most common CCHD. Tetralogy of Fallot involves 4 heart defects.
Mixing lesions means the defect mixes the pulmonary and systemic flows. Examples of this kind of CCHD are Truncus Arteriosus and Transposition of the great arteries.
Management and Treatment for Cyanotic Heart Disease
Treatment for CCHD may begin soon after birth, and the treatment of choice is usually surgery to correct the heart defect.
