COA- Coarctation of Aorta

Q) Not A complication of untreated coarctation of aorta
a) Endocarditis
b) CVA
c) Congestive heart failure
d) Pulmonary vascular disease


Coarctation of aorta is narrowing that diminishes the aortic lumen and produces an obstruction to the
flow of blood. In untreated patients complications might develop like endocarditis that occur at sites of
turbulent blood flow which is the site of narrowing,..........

Vascular ring

Q) Which is a true vascular ring?

a) Pulmonary artery sling

b) Double aortic arch

c) Cervical aortic arch

d) Origin of subclavian artery from descending aorta

30 ) b 

b) Double aortic arch

  • Double aortic arch is a classic example of a true vascular ring. It forms a complete ring around the trachea and esophagus, leading to compressive symptoms such as stridor, wheezing, or feeding difficulties.

  • Pulmonary artery sling is not a vascular ring. It is a congenital anomaly where the left pulmonary artery arises from the right pulmonary artery and passes between the trachea and esophagus but does not form a complete ring.

  • Cervical aortic arch is a rare anomaly and does not form a true vascular ring.

  • Aberrant origin of subclavian artery (e.g., aberrant right subclavian artery from the descending aorta) is considered a partial ring and usually causes less significant symptoms compared to true vascular rings.
