Aortic translocation, Senning procedure and right ventricular outflow tract augmentation for congenitally corrected transposition, ventricular septal defect and pulmonary stenosis

Abstract

The management of congenitally corrected transposition of the great arteries and associated lesions is frequently challenging. Significant pulmonary stenosis is a contraindication to the conventional double-switch. Instead repair may be accomplished by the Rastelli-Senning procedure, using an extracardiac conduit to achieve continuity between the morphological left ventricle and the pulmonary arteries. This however can be accompanied by conduit and intra-ventricular baffle-related problems that can necessitate surgical re-intervention and lead to late mortality. We describe the use of aortic translocation, Senning procedure and reconstruction of the right ventricular outflow tract using autologous tissue and valved homograft to facilitate anatomical correction in congenitally corrected transposition. The advantages of this technique in this group of patients and the implications for conduction tissue are discussed.
