What is the most common cyanotic congenital heart disease?
The most common defects associated with cyanosis are tetralogy of Fallot and transposition of the great arteries. These nine lesions constitute 85 percent of all congenital heart defects.
How is cyanotic congenital heart disease different?
Hyperoxia test is the initial method to distinguish CCHD from pulmonary disease. The test consists in measuring an arterial blood gas at room air and 100% inspired oxygen after 10 minutes. Neonates with congenital heart disease are usually not able to increase PaO2 above 100 mm Hg during 100% oxygen administration.
How is cyanotic heart disease diagnosed?
Tests to diagnose or rule out congenital heart disease include:
- Electrocardiogram (ECG). This painless test records the electrical signals in your heart.
- Chest X-ray.
- Pulse oximetry.
- Echocardiogram.
- Transesophageal echocardiogram.
- Cardiac CT scan and MRI .
- Cardiac catheterization.
What is cyanotic and acyanotic?
There are many types of congenital heart defects. If the defect lowers the amount of oxygen in the body, it is called cyanotic. If the defect doesn’t affect oxygen in the body, it is called acyanotic.
What are the common causes of cyanotic congenital heart disease?
Defects that cause cyanotic congenital heart disease
- a hole between the right and left ventricles of the heart.
- a narrow pulmonary valve.
- a thickening of the right ventricle muscles.
- a misplaced aortic valve.
What is cyanotic and acyanotic congenital heart disease?
Cyanotic congenital heart disease: Cyanotic heart disease involves heart defects that reduce the amount of oxygen delivered to the rest of the body. Acyanotic congenital heart disease: With this type of heart defect, blood contains enough oxygen, but it’s pumped throughout the body abnormally.
What is duct dependent congenital heart disease?
Duct-dependent congenital heart disease (DD-CHD) encompasses severe cardiac malformations that rely on postnatal patency of the ductus arteriosus to maintain adequate circulation. Prostaglandin E1 (PGE1) is most commonly used to maintain patency of the ductus arteriosus.
