D-TGA after atrial redirection surgery (Senning). Systemic venous return redirected to the left ventricle (LV), i.e., the atrial switch redirection of the inferior vena cava (IVC) and superior vena cava (SVC) flow to the LV (left). Atrial baffle redirecting pulmonary venous return to the right atrium, i.e., unobstructed pulmonary venous return, draining via an intracardiac tunnel at the back of the heart to the right atrium, and directed to the anatomic right ventricle (right). Also shown is how the intraatrial systemic venous Senning pathway returning to the LV is compressed in the anterior–posterior dimension.
