Flashcards in Paeds: Coarctation of the aorta (adult type): Dr Clarke Deck (9)
1

Path

Acyanotic
Out flow obstruction
Not duct dependent becomes severe over the years
Preductal-
While the PDA is open the right ventricle can maintain cardiac output.
Post ductal

2

Preductal symptoms

No murmur while PDA is open.
On closure HF and ESM

3

Post ductal symptoms

Symptoms -
Baby breathless, grey and collapsed
Hepatomegaly
Pulses are better n the arms than in the legs
BP lower in legs
No murmurs? ESM (check)

4

Signs

-Systemic HTN in arms esp right arm (lower in legs)
-ESM R sternal edge
-collaterals at the back -Radio-femoral delay (due to blood bypassing the obstruction via collaterals in the chest)

5

CXR

-rib notching (collateral intercostal arteries) -‘3’sign- notch in the descending aorta

6

ECG

LVH

7

Echo

Anatomy

8

Rx pre-ductal

Prostaglandin to keep PDA open while awaiting surgery.
Control HF prior to surgery

9

Post-ductal Rx

Stent through coarctation via cardiac catheter or surgery and ligation of PDA
