Modification of the Senning procedure in the double-switch operation: The triangular double-door technique.

We developed a modified Senning procedure in the double-switch operation for the patients with congenitally corrected transposition of the great arteries (ccTGA). In our technique, the right atrial (RA) free wall is not used as a baffle for draining systemic venous blood to the left atrium. Instead, a patch material is used for the baffling. A wide communication between the pulmonary venous chamber and RA is created by making the triangular double door with the RA-free wall, and the window is closed with in situ pericardial flap. We have successfully adopted this technique in our recent two consecutive ccTGA patients.
