truncus arteriosus gives rise to

ascending aorta and pulmonary trunk arise from

2

bulbus cordis gives rise to

right ventricle and smooth parts (outflow tract) of left and right ventricle arise from

3

primitive ventricle gives rise to

trabeculated left and right ventricles arise from

4

coronary sinus arise from

6

right horn of sinus venosus gives rise to

smooth part of right atrium arise from

7

Primitive PulmonaryVein

Smooth Part of Left Atrium

8

right common cardinal vein and right anterior cardinal vein gives rise to

SVC (superior vena cava) arise from

9

Blue Babies = Early cyanosis

Right to Left Shunts: 5 Terrible T's Tetralogy of Fallot Transposition of the Great Vessels Tricuspid atresia Truncus arteriosus TAPVR (Total anomalous pulmonary venous return)

10

Blue kids = Late Cyanosis

Left to Right Shunts VSD > ASD > PDA Eisenmenger's syndrome: L->R can turn to R->L shunt later

11

DiGeorge (22q11) syndromes is associated with

truncus arteriousus, tetralogy of Fallot is associated with

12

Down syndrome (Trisomy 21) is associated with

ASD, VSD, AV septal defect (endocardial cushion defect) is associated with

13

Congenital rubella is associated with

PDA, pulmonary artery stenosis, septal defects is associated with

14

Turner syndrome (45 XO) is associated with

coarctation of the aorta (pre ductal) and bicuspid aortic valve is associated with

15

Marfan's syndrome is associated with

Aortic insufficiency and dissection (late complication) is associated with

16

Infant of diabetic mother is associated with

transposition of the great vessels is associated with

17

Syphillitic aortitis

Degeneration of vasa vasorum --> degeneration of outer 2/3rds --> Aneurysm

18

1st part of aortic arch (Up at the top) develops into

part of maxillary artery (branch of external carotid) develops from

19

2nd part of aortic arch (Think S) develops into

Stapedial artery and hyoid artery develop from

20

3rd part of aortic arch (Think 3rd Letter) develops into

common Carotid artery and proximal part of internal Carotid artery develops from

21

4th part of aortic arch (Think 4 Limbs) develops into

Left: aortic arch Right: proximal part of subclavian artery develop from

22

6th part of aortic arch (Think very bottom) develops into

proximal part of pulmonary arteries and (on the left only) ductus arterioles develop from

23

5th part of aortic arch develops into

NOTHING!!
