A 28yo man with complains of headache and nose bleeds also has pain in the lower limbs on exertion. Exam: radio- femoral delay, cold legs with weak pulse and mild systolic murmur with normal S1S2. What is the most probable dx?
The key is coarctation of aorta. [headache and nosebleeds -
hypertension, pain in lower limb on exertion -> as reduced blood supply to leg due to coarctation, radio-femoral delay, cold legs with week pulse, mid- systolic murmur are all features of coarctation of aorta].
