Definition and Classification

Fig. 23.1 Coarctation and tubular hypoplasia of the aortic arch. Tubular hypoplasia of the aortic arch is usually associated with left ventricular outflow flow tract obstruction (asterisk) due to posterior malalignment of the infundibular septum (IS). Ao, ascending aorta; d, ventricular septal defect; LV, left ventricle; PA, pulmonary artery.
