Different types of anomalous bands, membrane, tendon, and venous valves have been described in the heart, but not within the great arteries of the heart. Here, we present a 3-year-old female child diagnosed to have a crescentic membrane originating from the superior8211;posterior wall of the pulmonary artery (PA) at bifurcation and obstructing the orifice of right PA producing significant gradient across the artery. Histopathology of this membrane showed fibrous tissue, and possibly this could be a membranous fold forming at the bifurcation of PA during the development of branch pulmonary arteries from the sixth aortic arch.
