OSCEs Flashcards
Features of aortic coarctation
- Radio-radio delay
- Radio-femoral delay
- Differing blood pressures in each limb
- Ejection systolic murmur at L sternal border
- Weak femoral pulse
On examination you find:
- Radio-radio delay
- Radio-femoral delay
- Differing blood pressures in each limb
- Ejection systolic murmur at L sternal border

What is your differential?
Aortic coarctation
Investigations and findings for aortic coarctation
ECG:
- Normal or RVH or LVH
CXR:
- Normal
- Posterior rib notching
- 3 sign
- Cardiomegaly
Echo:
- Narrowing in aorta
Aortic coarctation is associated with …
- Genetic syndromes e.g. Turners
- Bicuspid aortic valve
Features of aortic regurgitation
- Quincke’s sign (capillary nail bed pulsations)
- Collapsing pulse
- Bounding pulse
- Wide pulse pressure
- De Musset’s sign (head bobs with pulse)
- Diastolic ‘blowing’ murmur
- Laterally displaced apex beat
