Congenitally corrected transposition of the great arteries (ccTGA) is a complex congenital heart defect characterized by both atrioventricular and ventriculo-arterial discordance, which results in a physiologically “normal” circulation. There are various anatomical and clinical combinations in this disease entity. The natural course of ccTGA depends largely on the presence of associated defects such as ventricular septal defects (VSDs), pulmonary stenosis or atresia, more appropriately referred to as left ventricular outflow tract (LVOT) obstruction, and tricuspid valve (TV) anomalies.
