Abstract:
The late development of subvalvar stenosis following truncus repair is described. It may occur in patients with an overriding truncal valve and a relatively small ventricular septal defect (VSD) closed with an inappropriately sized patch. Management consisted in enlarging the VSD and closing it with a large, tailored patch. Consideration should be given to enlarging the VSD at the time of original repair if the truncal valve is overriding.
