case_images: The chest X-ray showed mild cardiomegaly with pulmonary congestion and the electrocardiogram showed sinus rhythm with left axis deviation (Figure 1). We performed echocardiography and diagnosed a common atrium, unbalanced complete AVSD with hypoplastic LV, patent ductus arteriosus, and moderate atrioventricular valve (AVV) regurgitation (Figure 2, Supplemental file 1).
case_images: Echocardiogram findings on admission showing four-chamber view (A), aortic arch (B). White arrow indicates suspected ventricular septal defect. RV, right ventricle; desc.Ao, descending aorta.

case_images: We performed echocardiography and diagnosed a common atrium, unbalanced complete AVSD with hypoplastic LV, patent ductus arteriosus, and moderate atrioventricular valve (AVV) regurgitation (Figure 2, Supplemental file 1). The diameter of the ventricular septal defect (VSD) was measured as 11 mm (upon later inspection, however, no VSD was present) (Figure 2); and bidirectional blood flow was shown in the ductus arteriosus without coarctation of the aorta (Supplemental file 2).

case_images: The anterior view (A) and lateral view (B) of digital 3D model. (C) Digital 3D image of the atrioventricular valve as viewed from the common atrium. (D) Digital 3D image of the mitral valve, interventricular septum, and left ventricular outflow tract as viewed from the apex of the left ventricle. LV, left ventricle; RV, right ventricle; MV, mitral valve; TV, tricuspid valve; IVS, intraventricular septum.
