A 1-month-old female baby presented with tachypnea, poor feeding, and a systolic murmur. An anterior-posterior chest radiograph showed cardiomegaly with pulmonary congestion. Surface electrocardiography revealed biventricular hypertrophy. Echocardiography showed a 1-cm defect connecting the transverse aortic arch and main pulmonary trunk (Figure 1). An axial view on computed tomography showed a large aortopulmonary communication (Figure 2). Three-dimensional reconstruction of a multidetector computed tomography scan demonstrated an aortopulmonary window between the roof of the main pulmonary artery and the floor of the transverse aortic arch (Figure 3). Although 3 variants of aortopulmonary window have been described, this case demonstrates a new, as yet unclassified type.
