Abstract

An aorticopulmonary septal defect (APSD) results from failure of proper conotruncal separation. The hemodynamic consequences of this lesion closely resemble that of other large left-to-right shunt defects, especially a patent ductus arteriosus (PDA). Failure to differentiate these 2 abnormalities has not infrequently led to an inappropriate surgical approach in pursuit of the far more common PDA. This report describes the two-dimensional echocardiographic (2-DE) recognition of an APSD in 2 premature infants. Survival of these delicate neonates indicates that successful surgery can be performed even in small infants. A thorough 2-DE examination for an APSD is recommended for any infant before proceeding to surgery for a suspected PDA, especially when cardiac catheterization has not been performed.
