The seeking for the optimal surgical treatment of
congenitally corrected transposition of the great arteries
(cTGA) is ongoing. Physiologic (conventional) repair
approaches, leaving the morphologic right ventricle (MRV)
on the systemic circulation side, cause systemic ventricle
and tricuspid valve failure, particularly in the long-term.
Double Switch operations (anatomic repair) were aimed to
convert the morphologic left ventricle to systemic ventricle
and MRV to pulmonic ventricle. Gradual improvement in the
early and midterm results of double switch operations in the
last 20 years rendered anatomic repair to become a preferred
procedure. Thanks to the preservation of ventricular functions
through anatomic repair, patients with congenitally cTGA
may survive longer with normal/near normal functional
capacity. However, studies with larger sample size and longer
follow-up duration are required to establish a more definite
judgement.
