Di-George syndrome was noted in one patient, who presented with hypocalcemia and T cell dysfunction. According to the Celoria-Patton classification, IAA can be classified into three types according to the location of the anomaly: 1. The combination of these defects significantly increases the surgical risk. Faulty embryological development of the aortic arch (thought to occur during the 5th to 7thweek of intrauterine life). Both presented as tachypnea, poor appetite and increasing cyanosis during the first week of life. Autopsy confirmed this diagnosis.ĪB - Two neonates with a combination of truncus arteriosus and interruption of the aortic arch, so-called type A4 of the Van Praagh classification, are reported. In both, a homograft was used to connect the right ventricle to the pulmonary artery, while the arch continuity was established by direct anastomosis of the aortic arch to the descending aorta. Genetic Considerations: Approximately 50 of newborns with truncus arteriosus have associated genetic disorder, most commonly the chromosome 22q11.2 deletion syndrome (20 of the cases). The combination of these defects significantly increases the surgical risk. Two neonates with truncus arteriosus (TA) and type B interrupted aortic arch are reported. Type A4: This type is defined by presence of aortic arch hypoplasia, coarctation or interrupted aortic arch and a large PDA. The combination of those defects significantly. Both presented as tachypnea, poor appetite and increasing cyanosis during the first week of life. Five patients with a combination of truncus arteriosus and interruption of the aortic arch are reported. It is usually classified as a conotruncal anomaly. N2 - Two neonates with a combination of truncus arteriosus and interruption of the aortic arch, so-called type A4 of the Van Praagh classification, are reported. Truncus arteriosus is a cyanotic congenital heart anomaly in which a single trunk supplies both the pulmonary and systemic circulation, instead of a separate aorta and a pulmonary trunk. T1 - Persistent truncus arteriosus associated with interrupted aortic arch ![]()
