At what weeks does the heart develop in the embryo
|
5th-8th weeks
|
|
What are 5 cyanotic heart diseases?
|
1- Tetralogy of Fallot
2- Transposition of the Great Arteries- Aorta from right ventricle 3- Tricuspid Atresia- usually ASD with R to L shunt 4- Truncus arteriosus- aorta and pulm share trunk 5- Total anomalous pulmonary venous return |
|
If you see a cyanotic pt, you can think obstruction in right side and abnormal connection from right to left
|
Notes

Coarctation of the Aorta
|
increased blood pressure to upper extremities, decreased BP to lower extremities
-Dilation of aorta and aortic valve ring (regurgitation) -Increased risk for dissection -Leg claudication -Decreased renal flow leads to hypertension by RAA system |
