English: (a) Schematic drawing of Arterial Switch operation showing Le Compte manoeuvre with the translocation of aortic and pulmonary arteries. (b) Schematic drawing of an atrial switch (Mustard/Senning) for transposition of the great arteries. Systemic (blue) blood is directed from the superior caval vein and inferior caval vein into the left atrium, then via the mitral valve to the left ventricle and then to the pulmonary artery. Pulmonary (red blood) is directed from the pulmonary veins to the right atrium, then via the tricuspid valve to the aorta. Images produced with permission from Gemma Price.
