| Jatene procedure (operation) | syn. arterial switch operation. An operation used in complete transposition of the great arteries, involving removal of the aorta from its attachment to the RV, and of the pulmonary artery from the LV, and the reattachment of the great arteries to the contralateral ventricles, with reimplantation of the coronary arteries into the neo-aorta. As a consequence, the left ventricle supports the systemic circulation. (Jatene AD et al. Anatomic correction of transposition of the great vessels. J Thorac Cardiovasc Surg 1976;72:364-370.) see also Lecompte manoeuvre. |
| juxtaposition of atrial appendages | A rare anomaly seen in patients with transposition of the great arteries and other complex congenital heart defects (dextrocardia, tricuspid atresia, etc.), wherein the atrial appendages are situated side by side. The right atrial appendage passes immediately behind the transposed main pulmonary artery in patients with leftward juxtaposition of atrial appendages. |
