Historical Evolution of Surgery for Transposition of Great Arteries (TGA)

The science and art of cardiac surgery has made rapid development in the past 65 years. The surgery for transposition of great arteries (TGA) symbolises the manner in which cardiac surgery has progressed. The eventually successful solution in the form of the now popular arterial switch operation (ASO) was elucidated after multiple contributions from several surgical stalwarts and geniuses over more than 35 years (Figure 1). This review traces the various milestones along this journey.
