Opinion statement
The arterial switch operation (ASO) is now the most frequently performed surgical correction in individuals with dextro-transposition of the great arteries (D-TGA). Patients who undergo this procedure as neonates have overall good clinical outcomes yet continued clinical follow-up is important to evaluate for postoperative complications. In this group, the highest mortality is in the immediate postoperative period and is generally associated with reimplantation of the coronary arteries. As these patients live into adulthood, longitudinal follow-up for other ASO complications including neo-pulmonary stenosis, right ventricular outflow tract (RVOT) obstruction, or neo-aortic root dilation and resulting aortic insufficiency should be performed. In adults, extra care should be taken to identify and treat traditional cardiovascular risk factors as individuals with coronary obstruction may not present with typical anginal symptoms. Management of these patients should be performed in collaboration with an adult congenital heart center of excellence. This population offers a unique opportunity to provide timely feedback to adult congenital heart community of providers regarding late outcomes from surgical intervention and in the next decade will hopefully demonstrate a model for clinical feedback cycles in lifelong congenital care.
