Tetralogy of Fallot with double aortic arch and aortopulmonary window: a very rare trifecta

摘要

Tetralogy of Fallot with an aortopulmonary window and double aortic arch is very rare. This complex coexistence may be over a wide clinical spectrum. Herein, we present an asymptomatic 8-day-old infant who was diagnosed as having tetralogy of Fallot, double aortic arch, and an aortopulmonary window using transthoracic echocardiography while being examined for microcephaly.Tetralogy of Fallot is the most common cyanotic CHD, with a prevalence of approximately 0.5 per 1000 live births.1 Associated anomalies are frequently seen.2 Here, we present a neonate diagnosed as having tetralogy of Fallot, a double aortic arch, and an aortopulmonary window by echocardiographic imaging. To our knowledge, this is the first case report of this triad of congenital heart anomalies in the literature. This case also illustrates that complex and very rare cardiac defects may be asymptomatic in the early neonatal period and progressively have severe congestive heart failure symptoms in a few weeks.
