Anatomical correction of atrioventricular discordance using three-dimensional replica

Surgical experience with {S,L,D} segmental anatomy of atrioventricular discordance with double-outlet right ventricle is extremely rare. In addition to ordinary cardiac examination, we reviewed electrophysiological studies and a three-dimensional cardiac replica (crossMedical, Inc., Kyoto, Japan). Consequently, we preoperatively confirmed the intracardiac rerouting line and the appropriate right ventricle incision line. A Senning procedure, intracardiac rerouting, and subaortic stenosis resection were performed in a 2.6-year-old patient (weight, 10.6 kg). The three-dimensional cardiac replica contributed definitively to the anatomical correction.
