A: The chest computed tomography angiography in the coronal plane reveals abnormal pulmonary vein connections. The vertical vein (white arrow) connects the left pulmonary vein to the left brachiocephalic vein (orange arrow). The right upper pulmonary vein (blue arrow) also connects to the superior vena cava (red arrow). The green arrow highlights the mixture of blood and dye at the site of the connection. B: The axial plane at the ventricular level shows an intact interatrial septum and significant right atrium and ventricle dilation. C: The axial plane at the superior vena cava level reveals an abnormal connection of the right upper pulmonary vein to the superior vena cava, indicated by the blue arrow and red arrow, respectively, resulting in a mixture of blood and contrast. D: The coronal plane shows an abnormal connection between the right upper pulmonary vein (blue arrow) and the superior vena cava (red arrow)
