MCQ : CHD-05
1-Day-Old Neonate. What is your diagnosis?
A – Coarctation of the aorta
B – Aortic valve stenosis
C – Pulmonary valve stenosis
D – Patent ductus arteriosus
Right answer is A: Coarctation of the aorta
Coarctation of the aorta is a narrowing of the aorta, most commonly occurring just beyond the left subclavian artery.
Coarctation of the aorta causes an increase in the upper extremity blood pressure, resulting in two common presentations. The first is the neonatal presentation that is associated with left ventricular dysfunction and shock.
The second presentation occurs in older children and adults. Coarctation of the aorta in this scenario results in upper extremity hypertension, leading to early coronary artery disease, aortic aneurysm, and cerebrovascular disease.
