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.
先天性矫正型大动脉转位及相关病变的治疗常常具有挑战性。严重的肺动脉狭窄是传统双调转术的禁忌证。取而代之的是,可通过Rastelli-Senning手术完成修复,利用心外管道来实现形态学左心室与肺动脉之间的连续性。然而,这可能会伴随管道及心室内挡板相关的问题,这些问题可能需要再次手术干预并导致晚期死亡。我们描述了使用主动脉移位、Senning手术以及利用自体组织和带瓣同种异体移植物重建右心室流出道,以促进先天性矫正型大动脉转位的解剖学矫正。讨论了该技术在这类患者中的优势以及对传导组织的影响。
