1. Embryology of AORTA

11. Hypolplasia of Ascending
aorta
0.2 per 1000 live births
Lethal if left untreated
HLHS

12. COA
5-7 %
PREDUCTAL
POSTDUCTAL
ASSOCIATED with VSD,
COMPLEX HEART DIEASES

14. PDA
CLOSES IN 2 days
Associated with COA,TGA ,VSD.
LVH, PA dilatation

15. Aberrant Right Subclavian or Brachiocephalic
Artery
Type:
1 . Behind esophagus - 85%
2 bet esophagus and trache
3. In front of trachea
Mc ARCH anomaly

16. Rt Innominate
compression syndrome

17. Interrupted aortic arch
associated with a significant mortality and
morbidity

18. Bovine aorta
Mc branching anomaly
10 to 23%

19. Vertebral variant
Mc bet LT CCA & SCA
Proximal duplication
Last branch of arch

20. Thyroid Ima Artery
16.9 %
AAR
Brachicephalic trunk

21. Rt aortic arch
<1 %
Rt 4th arch prrsists
Types :
With LT Aberrant SCA
MIRROR IMAGE - Cyanotic heart disease

22. Double aortic arch
Persistent of aortic system
Divide and reform

23. Cervical aortic notch
3rd arch persists and 4th arch abnormal
regression
Pulsatile mass in neck
No anomaly association
Associated MC with Rt aortic notch

24. Intercostal artreies
anterior intercostal arteries arise from the inter-nal
mammary artery.
95% of cases, the first,second, and third posterior
intercostal arteries originate from the superior
intercostal artery - CCT
remaining intercostal and subcostal spaces are
supplied by paired dorsal branche
First 3 spaces - more associated with anomalies

25. Bronchial artery
anomalies
3rd To 7th intercostal spaces
Common bronchial trunk 45%
From concavity,of aorta 15%
LT Broncho intercostal trunk 4%

28. Celiac artery variation

30. Renal artery variation
Accessory
Aberrant
Prehilar branching
