|
What are the two types of cyanotic congenital heart problems?
|
- Defects decreasing pulmonary blood flow
- Mixed defects |
|
|
What are the three defects that decrease pulmonary blood flow?
|
- Tetralogy of Fallot (TOF)
- Tricuspid Atresia (TA) - Pulmonary Atresia (PA) |
|
|
What are the four characteristics of TOF?
|
- VSD
- Pulmonary stenosis - Overriding aorta - Right ventricular hypertrophy |
|
|
During TET spells what does the infant and child do?
|
- Children: squatting
- Infants: knee to chest position |
|
|
What is TA?
|
When the tricuspid valve does not develop so there is no connection between the right atria and right ventricle. VSD is present
|
|
|
What happens to the right ventricle in TA?
|
It is hyperplastic
|
|
|
What treatment is done for TA?
|
- Give PGE1 to keep ducts open.
- Surgery, possible 3 stage procedure |
|
|
What is PA?
|
Failure of the pulmonary valve to develop, blood enters right atria and ventricle and pumped through ASD to the left ventricle
|
|
|
What heart sound would you expect to hear on a child with PA?
|
only S2
|
|
|
What heart sound would you expect to hear on a child with TA?
|
only S1
|
|
|
What is the treatment for PA?
|
- PGE1 till surgery
- Surgery |
|
|
What does survival depend on with PA?
|
the PDA
|
|
|
Is there profound cyanosis in PA?
|
Yes
|
|
|
What are the four mixed defects?
|
- Transposition of Great Arteries (TGA)
- Hypoplastic Left Heart Syndrome (HLHS) - Truncus Arteriosus (TA) - Total Anomalous Pulmonary Venous Return (TAPVR) |
|
|
What is TGA?
|
The aorta is coming from the right ventricle and the pulmonary artery is coming from the left ventricle
|
|
|
What is survival dependent of with TGA?
|
Patency of the foreman ovale and ductus arterious
|
|
|
Will a newborn with TGA respond to oxygen?
|
No
