![]() ![]() The origin of the left carotid artery (LCA), which receives oxygenated blood from the ascending aorta, is clearly differentiated from that of the left subclavian artery (LSA) and the remainder of the descending aorta, which is supplied by the pulmonary artery with mixed blood because of the presence of a ventricular septal defect with left-to-right shunting. The main pulmonary artery (MPA) is severely dilated because of the pulmonary hypertension. ![]() The patient also presented differential cyanosis with clubbed fingers of the left hand and toes of both feet.Īngiographic reconstructions of images obtained with a 64-slice multidetector computed tomography unit, performed with a low-dose radiation protocol (80 kV, 50 mA), show anterior (Figure 1), lateral (Figure 2), and posterior (Figure 3) views. Interrupted aortic arch (IAA) is defined as the loss of luminal continuity between the ascending and descending aorta. The physical examination was remarkable for a single, strong second heart sound, secondary to pulmonary hypertension, and asymmetric pulses, which were stronger in the right arm and both carotids than in the other limbs. This keeps the blood from reaching the lower body because the aorta is. Interrupted aortic arch is an extremely rare anomaly in adult patients. We present the case of an 8-year-old boy with type B interrupted aortic arch. Interrupted aortic arch (IAA) is a problem where the aorta has an absent portion. The suspicion of coarctation of the aorta can be made from a combination of physical findings including systolic ejection murmur, the murmurs of collateral blood vessels, diminished or absent femoral pulse, and difference in blood pressure between arms and legs. The descending aorta is supplied by the pulmonary artery through a patent ductus arteriosus. In type B interrupted aortic arch, the most common form of the condition, the separation is produced between the left carotid and subclavian arteries and is associated with an interventricular communication. Type A: The disruption is located distal to the left subclavian artery this is the second most common disruption represents approximately 13 of the cases. Our hearts are comprised of four chambers, two upper chambers, the right atrium and left. In the patients with associated VSD and PDA as well as in the one patient with associated truncus arteriosus, the primary correction-direct anastomosis of the interrupted segments without prosthesis and VSD closure and in the case with truncus, the additional positioning of a valve-bearing allograft conduit from the right ventricle to the pulmonary artery-has been more successful than a two-step approach with initial pulmonary artery banding.Interrupted aortic arch is a congenital malformation characterized by a complete separation between the ascending aorta and the descending aorta. Explain modalities to improve care coordination among interprofessional team members in order to improve outcomes for patients affected by interrupted aortic arch. Interrupted Aortic Arch (IAA) is a rare birth defect of the heart. One patient with interrupted aortic arch type C and another infant with associated truncus arteriosus were successfully corrected on day 9 and day 17 of life, respectively. The operative mortality in 22 patients with associated ventricular septal defect (VSD) and persistent ductus arteriosus (PDA) was reduced from 43% (in seven patients seen up until 1979) to 7% (in 15 patients seen since 1980). Among our 36 patients with interrupted aortic arch, 27 were operated on. Accurate angiography with visualization of the interrupted aortic arch and delineation of associated cardiac malformations is of prime importance for the surgical management and prognosis. The chances of survival for patients with interruption of the aortic arch depend mainly on early recognition and medical treatment before symptoms of cardiogenic shock appear, and specifically on early operative repair after the exact diagnosis has been established. ![]()
