Abstract
Congenitally corrected transposition of the great arteries (ccTGA) has two major cardiac malformations, including atrio-ventricular discordance, together with ventriculo-arterial discordance. One of the biventricular repair (BVR) for ccTGA is “functional repair”, such as closure of ventricular septal defect, repair or reconstruction of pulmonary pathway, and/or tricuspid valve replacement or repair, in which the anatomical right ventricle is used as systemic ventricle. Another type of BVR is “double switch operation”, which consists of an atrial switch and an arterial switch or a ventriculo-arterial switch (Rastelli type procedure), so the anatomical left ventricle is used as systemic ventricle. Although, results of these surgeries have much improved more recently, the long term precise outcomes are still unidentified and controversial, especially concerning with indication and some optional procedures of double switch.
