Imaging in Babies with Heart Defects (IMAGE)
Caption
Cardiac photon-counting CT (PCCT) in a 174-day-old male infant with complex congenital heart defect. (A) Contrast-enhanced axial PCCT image shows sonographically suspected sinus venosus defect with partial anomalous pulmonary venous connection. (B) Contrast-enhanced coronal PCCT image. (C) Anterior view of three-dimensional reconstruction shows a partial anomalous pulmonary venous connection of two separate lung veins from the right upper and middle lobe to the right superior vena cava (red arrows) and a persisting left superior vena cava (yellow arrow). (D) Three-dimensional reconstruction, posterior view. The diagnosis was confirmed at PCCT, and PCCT allowed for visualization of the partial anomalous pulmonary venous connection of two separate lung veins from the right upper and middle lobe to the right superior vena cava. One lung vein drains correctly to the left atrium (green arrow). A sinus venosus defect, an atrial septum defect, an enlarged right atrium and a persisting left superior vena cava are shown. The only regular confluence of a single right lung vein into the left atrium is shown (D; green arrow). Image quality was rated as 5 of 5 (optimal).
