Unusual association of aortic valve stenosis with ventricular septal defect and pulmonary atresia: Differentiation from truncus arteriosus with truncal valve stenosis.

ABSTRACT

Stenosis of systemic semilunar valve in cyanotic congenital heart defects is rare. It can happen in truncus arteriosus with truncal valve stenosis and the very rare anomaly of tetralogy of fallot with aortic valve stenosis. Here we describe a neonate with pulmonary atresia, ventricular septal defect and associated aortic valve stenosis and discuss the points of differentiation from truncus arteriosus.
