Truncus arteriosus

Truncus arteriosus (TA) is a rare congenital cardiovascular anomaly characterized by a single arterial trunk arising from the heart by means of a single semilunar valve (<I>i.e.</I> truncal valve). Pulmonary arteries originate from the common arterial trunk distal to the coronary arteries and proximal to the first brachiocephalic branch of the aortic arch. TA typically overrides a large outlet ventricular septal defect (VSD). The intracardiac anatomy usually displays situs solitus and atrioventricular (AV) concordance.

We present the first reported case of truncus arteriosus, interrupted aortic arch with hypoplastic tricuspid valve and right ventricle and anomalous left coronary artery orifice in a neonate in whom successful palliation was performed using two-staged procedure.
