Critical coarctation of the aorta

5 Interesting Facts of Critical coarctation of the aorta 

  1. Congenital narrowing of the proximal thoracic aorta (typically as stenosis in the juxtaductal position), hypoplasia of the transverse aortic arch, or stenosis of the abdominal aorta
  2. Heart failure results during ductal closure when coarctation is significantly stenotic owing to acute development of left ventricular outflow obstruction; manifestations closely resemble those of myocarditis
  3. Decreased femoral arterial pulse volume compared to right brachial artery, raised upper limb blood pressures compared with lower limb, and differential cyanosis raise concern of coarctation of the aorta
  4. Response to prostaglandin infusion is consistent with a ductal-dependent congenital heart lesion
  5. Differentiate and diagnose with transthoracic echocardiography
