The number of adults with congenital heart disease (CHD) has steadily increased as medical and surgical treatment of congenital heart lesions—whether simple or complex—continues to improve. Over the past half century advances in surgical technique have continued with the evolution of traditional surgical repair and introduction of new surgical procedures for complex lesions previously considered to be irreparable. This article describes the rich history of surgical repair, important surgical considerations specific to the adult undergoing primary or reoperative cardiac repair or palliation, the most common types congenital heart lesions and associated cardiac procedures (including cardiac transplantation) performed in the adult population, as well as considerations regarding the optimal surgical environment and current surgical training and education.
