The Editor,

A 3-year-old male, diagnosed as a case of dextroposed transposition of great arteries (d-TGA) preoperatively, underwent Senning's operation. TOE examination performed after induction of anaesthesia (using Philips Sonos 7500, USA) revealed pulmonary artery (PA) positioned posterior to the aorta [Figure 1] and ventriculoarterial discordance [right ventricle (RV) draining into the aorta and left ventricle (LV) draining into the PA] [Figure 2]. Dynamic left ventricular outflow tract obstruction (LVOTO) was present. Other features were enlarged right atrium and RV; intact interventricular septum (IVS); atrial septal defect (ASD) measuring 7 mm; and normal position of left atrial appendage and coronary arteries. On cardiopulmonary bypass (CPB), after aortic cross-clamping and cardioplegic arrest, Senning's operation was performed in three layers. No flow obstruction was observed in systemic venous chamber and pulmonary venous baffle [Figure 3] after termination of CPB. RV (systemic ventricle) and LV function were good.

Senning's operation is still performed routinely in developing countries. Ventriculoarterial discordance; bulging of IVS toward LV; and the position of PA parallel and posterior to the aorta (double-barrel appearance) are important features associated with d-TGA. During Senning's operation, a baffle is created in the atrium, which redirects systemic venous flow to LV and pulmonary venous flow to RV. Obstruction to the pulmonary and systemic venous pathway [1] may occur postoperatively, which should be ruled out in the post-CPB period. TOE is indicated for the evaluation of intra- or extra-cardiac baffles [2] and ventricular function following the Senning's procedure.
