[A successful operation by de Leval's procedure in corrected transposition of the great arteries with ventricular septal defect and pulmonary atresia].

A ten-year-old boy with C-TGA (S, L, L) associated with ventricular septal defect and pulmonary atresia underwent an intracardiac repair successfully. Its repair was consisted of VSD closure by de Leval's procedure and relief of pulmonary atresia by means of external valved conduit (18 mm Inonescu-Shiley valved conduit). Sutures for VSD closure were placed to upper half margin of VSD from the anatomic right ventricle and lower half margin from the anatomical left ventricle, as which de Leval and co-workers have described previously. De Leval's procedure is superior than other VSD closure methods at the point of reduced A-V block, relatively easy operative technique, and good operative field.
