Contrast bidimensional echocardiography in the morphologic and functional postoperative evaluation of the Senning technique for complete transposition of the great vessels.

Contrast bidimensional echocardiographic (2DE) studies were performed in eight patients with d-transposition of the great vessels in the postoperative period of the Senning technique. Contrast was injected into a peripheral vein of all patients, and into the arterial atrium in five in the postoperative period. The 2DE projections used were the four-chamber apical view and four-chamber subcostal view. In all patients it was possible to see and identify the new atrial cavities which greatly resembled the actual anatomy. Early postoperative alternating injections of contrast in both new atria not only achieved the main purpose of delineating the real anatomy, but also permitted more definitive identification of residual shunts.
