Furthermore, the baffles for systemic and pulmonary venous return have been shown to place patients at long-term risk for the development of atrial arrhythmia, though this risk might be mitigated by having a systemic left ventricle. Patients with cc-TGA are prone to developing atrioventricular block (AVB) requiring pacemaker implantation regardless of operative intervention. There are multiple long-term complications that can occur after anatomic repair for cc-TGA.

This reduces the long-term deleterious risk of systemic right ventricular (RV) failure, and the propensity for progressive systemic TV insufficiency.
The anatomic repairs allow for the left ventricle to become the systemic ventricle. An additional variation includes a hemi-Mustard with a bidirectional Glenn shunt. Surgical anatomic correction, depending on underlying associated cardiac anomalies, can be obtained with either a double switch operation (Senning/Mustard atrial switch and arterial switch) or an atrial switch (Senning/Mustard) with a Rastelli operation (ventricular septal defect closure with a baffle to the aorta and a right ventricle to pulmonary artery conduit). Associated anatomic cardiac abnormalities include ventricular septal defects and pulmonary and subpulmonary obstruction, coarctation and Ebstein’s anomaly of the tricuspid valve (TV). Congenitally corrected transposition of the great arteries (cc-TGA) is an uncommon cardiac defect accounting for less than 0.5% of congenital heart disease.
