Characteristic signs of a rare abnormality of the major vessels, an aortopulmonary septum defect, are described. This pathology is associated with shunting and discharge of blood from the left to the right and an early development of pulmonary hypertension. The clinical course of the defect depends on the degree of the hemodynamic impairment in the pulmonary circulation. It has been elucidated that aortography with catheterization and contrast examination of the right portions of the heart is the method of choice in the diagnosis of this defect. Surgical correction of the defect is the only radical method of treatment. The long-term results of surgical treatment are promising.
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.
