Özet

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.
