Coarctation of the aorta
Aortic coarctation accounts for 5%-8% of all congenital heart defects and may occur as an isolated defect or in combination with ventricular septal defect and bicuspid aortic valve. Infants typically present with signs of heart failure as the ductus arteriosus closes due to significant increase in afterload with left ventricular strain and pulmonary congestion.
Previously undiagnosed children and adults typically present with hypertension. Systolic pressures are usually higher in the upper extremities than in the lower extremities. Femoral pulses are usually diminished or delayed. Lower extremity claudication occurs with exertion. Lower extremity systolic pressures may be unobtainable.
