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.
主肺动脉间隔缺损（APSD）是由于动脉干未能正常分隔所致。该病变的血流动力学后果与其他大型左向右分流性缺损非常相似，尤其是动脉导管未闭（PDA）。未能区分这两种异常情况常常导致在治疗更为常见的PDA时采用不恰当的手术方法。本报告描述了2例早产儿主肺动脉间隔缺损的二维超声心动图（2-DE）识别情况。这些脆弱新生儿的存活表明，即使是小婴儿也能成功进行手术。对于任何疑似PDA而准备进行手术的婴儿，尤其是未进行心导管检查的婴儿，建议进行全面的主肺动脉间隔缺损二维超声心动图检查。
