What are the predictors of early and long-term outcomes following the arterial switch operation for transposition of the great arteries?
Complex anatomical features such as VSD, coronary anomalies, and aortic coarctation are strong predictors of poor reoperation-free survival after the arterial switch operation for TGA.
ASO remains the procedure of choice for the treatment of various forms of TGA with acceptable early and later outcome in terms of overall survival and free reoperation. Strong predictors for poor overall free-reoperation survival are complex TGA, VSD, coronary anomalies, aortic coarctation and LVOTO or moderate PAS. The pulmonary artery reconstruction using a single 'pantaloon patch' seems to offer less residual stenosis. Patients with a VSD and a significant mismatch between the neo-aortic root and distal aorta are at a higher risk for developing postoperative neo-AVI.
