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
In the fetus, ductus arteriosus is kept open by
Prostaglandin E2 made from the placenta
What is Eisenmenger syndrome?
Reverse shunting- cyanosis and clubbing of the nails

PDA
PDA effect on cyanosis
Differential cyanosis
-pink upper body and cyanotic lower body
Treatment for PDA
Indomethacin inhibits Prostaglandin E2 (vasodilator)
What is cyanosis value?
SaO2<80%
Left to right shunts
VSD, ASD, PDA
Tricuspid Atresia
ASD with right to left shunt
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
Rib notching seen in
Coarctation of the aorta
