Although most cases occur in normally connected great arteries, interrupted aortic arch. Besides a ventricular septal defect, IAA can be associated with other more complicated cardiac anomalies for example, transposition of the great arteries, truncus arteriosus, aortopulmonary window, single ventricle, aortic valve atresia, right-sided ductus, and double-outlet right ventricle.Ĭopyright © 2023, StatPearls Publishing LLC. Interrupted aortic arch (IAA) is a relatively rare genetic disorder that usually occurs in association with a nonrestrictive ventricular septal defect (VSD) and ductus arteriosus or, less commonly, with a large aortopulmonary window or truncus arteriosus. Due to this malalignment, there could be left ventricular outflow tract obstruction. Interrupted Aortic Arch Andrea Luna-Nelson, Alejandro Lopez-Magallon, Michael D. Type A is less common (3045) and type C is rare. 20), of which type B is the most frequent (5070). Depending on the site of discontinuity, IAA is classified into three types (see Fig. This lesion is present is approximately 73% of all cases. Interrupted aortic arch (IAA) is a structural heart defect characterized anatomically by a discontinuity (interruption) along the aortic arch. There is posterior malalignment of the conal septum additional to the interrupted aortic arch, producing a ventricular septal defect as an associated lesion. Interruption of the aortic arch (IAA) is defined as the congenital absence of the anatomical and luminal continuity between the ascending and descending. IAA is a ductus dependent lesion since this is the only way the blood flow can travel to places distal to the disruption. The first report of a trisomy of distal chromosome 5q associated with interrupted aortic arch interruption is reported, and it is concluded that gene dosage. In an IAA, there is an anatomical and luminal disruption between the ascending and descending aorta. Interrupted aortic arch is an anomaly that can be considered the most severe form of aortic coarctation. Approximately 97% of babies born with a non-critical congenital heart disease have a life expectancy of one year of age, and approximately 95% are expected to live around 18 years of age.Ī rare type of congenital heart disease is an interrupted aortic arch (IAA), which affects approximately 1.5% of congenital heart disease patients. The survival rate of patients with congenital heart disease will depend on the severity, time of diagnosis, and treatment. the congenital heart disease represents approximately 4.5% of all neonatal deaths. CTHDs include the tetralogy of Fallot (TOF), double-outlet right ventricle, transposition of the great arteries (TGA), interruption of the aortic arch (IAA). In the United States, congenital heart disease affects 1% of births (40,000) per year, of which 25% have critical Congenital heart disease. It has an incidence of 8 cases of every 1000 live birth worldwide. IAA repair and VSD closure are planned as second stage surgery.Congenital heart disease is an abnormal formation of the heart or blood vessels next to the heart. Bilateral PA banding was done as first stage surgery. Almost all babies born with an IAA also have a hole between the lower chambers of the heart called a ventricular septal defect (VSD). The patient was managed with two stages surgery. An interrupted aortic arch can be related to a genetic disorder such as 22q11.2 deletion syndrome (also known as DiGeorge syndrome), so genetic testing usually is recommended. Cardiac MSCT showed LSCA and descending aorta come from PDA. The echocardiography showed aortic interruption between the left common carotid artery (LCCA) and left subclavian artery (LSCA). The CXR examination revealed absent of aortic knob. ![]() Patients with interrupted aortic arch (particularly those with type B) often have a genetic disorder called DiGeorge syndrome. IAA is frequently associated with ventricular septal defects (VSD) and a bicuspid aortic valve. ![]() Physical examination revealed b lood pressures and oxygen saturation were lower at upper right arm and both legs. This defect is usually associated with a large ventricular septal defect (VSD). Interrupted aortic arch (IAA) is a congenital anomaly where there is interruption or discontinuation of a segment of the aortic arch. A four months old female baby was referred with dyspnea, failure to thrive and recurrent respiratory infection. In the absence of surgical repair, mortality approaches 75% in the first month of life and 90% by one year. Its hallmark feature is a lack of luminal continuity between the ascending aorta and the descending aorta. Interrupted aortic arch (IAA) is a rare genetic disorder of the cardiovascular system, present in approximately 2 cases per 100,000 live births and comprising 1.5% of all cases of congenital heart disease (CHD).
