Total anomalous pulmonary venous drainage (TAPVD) repair. a Three-dimensional (3D) CT reconstruction. An adult patient presenting with breathlessness had a computed tomographic pulmonary angiogram (CTPA). A single left pulmonary vein (LPV) crosses the midline to form a single confluence with the right pulmonary veins (RPV) and joins the left atrium (LA) via a baffle (white arrow). A residual anomalous left superior pulmonary vein (white arrowhead) is seen draining into the left brachiocephalic vein (LBCV); presumed previous type 4 TAPVD. Incidentally the pulmonary vessels in the right lower lobe were tortuous and dilated with a suspected arteriovenous malformation. b Three dimensional (3D) CT reconstruction. A paediatric patient with a Type 2 TAPVD repair. The pulmonary veins (white arrowheads) can be seen forming a single venous confluence posterior to the LA. This has been reconnected to the LA via a small baffle (white arrow). c Sagittal CT image. Type 2 TAPVD. A single venous confluence of the pulmonary veins is present (asterisk) posterior to the left atrium (LA) with a focal narrowing where this has been surgically connected to the LA (black arrow). d Axial CT image. This again shows the posterior venous confluence of the pulmonary veins (black arrow)
