Aortopulmonary window (APW) is a septation defect between the ascending aorta and main pulmonary artery, and it accounts for 0.2-0.6% of all congenital heart diseases. The diagnosis is made by detecting the defect between the ascending aorta and pulmonary artery while both semilunar valves are fully developed. Based on the anatomical characteristics, APW is classified into four types: proximal (Type 1) defect, distal (Type 2) defect, total (Type 3) defect and intermediate (Type 4) defect. APW is traditionally treated by surgery, and there are a few reports about transcatheter APW closure in infancy. Only defects with adequate superior and inferior rims can be considered for device closure. We describe two cases who underwent transcatheter APW closure with the Amplatzer duct occluder-I (ADO-I). Our experience shows that the ADO-I can achieve good results in closure of APW for selected patients.
主肺动脉窗（APW）是升主动脉与主肺动脉之间的间隔缺损，占所有先天性心脏病的0.2 - 0.6%。诊断是在两个半月瓣完全发育的情况下，检测升主动脉与肺动脉之间的缺损。根据解剖学特征，APW分为四种类型：近端（1型）缺损、远端（2型）缺损、完全（3型）缺损和中间（4型）缺损。传统上，APW通过手术治疗，关于婴儿期经导管封堵APW的报道较少。只有具有足够上下边缘的缺损才考虑进行器械封堵。我们描述了两例使用Amplatzer动脉导管封堵器-I（ADO-I）进行经导管APW封堵的病例。我们的经验表明，ADO-I对于选定的患者在封堵APW方面可取得良好效果。
