Successful closure of ventricular septal defect through a left-sided ventriculotomy in corrected transposition of the great vessels.

Corrected transposition of the great vessels is often associated with other cardiac anomalies. Ventricular septal defect (VSD) is the most common among them. Closure of a VSD is usually performed through a right-sided ventriculotomy. We had previously closed the VSD through the right-sided ventricle in 2 patients with corrected transposition of the great vessels and in 2 others with double-outlet right ventricle with ventricular inversion, which resulted in complete heart block. Recently we have closed the VSD through the left-sided ventricle in 3 patients with corrected transposition, and no block resulted.
