Assembled silicone molded model used for simulation of the arterial switch operation. A, Superior aspect of the model showing the typical anterior-posterior relationship between the ascending aorta (Ao) and the main pulmonary artery (PA). The right coronary artery (RCA) and left coronary artery arise from their respective sinuses. The space around the coronary arteries is filled with beige-colored silicone to simulate epicardial fat. B, Basal view of the ventricles looking from the cardiac apex, showing all the cardiac valves. C, Completed models mounted on a basal plate and supporting columns. AV, Aortic valve; Cx, circumflex coronary artery; LAD, left anterior descending coronary artery; TV, tricuspid valve; MV, mitral valve; PV, pulmonary valve.
