A single stage repair of coarctation and closure of VSD is an attractive choice in these patient but complex coarctations with tubular hypoplasia usually require circulatory arrest or selective cerebral perfusion.9-11 We have left the VSD open in 4 cases and have observed that in 2 cases the VSDs have closed significantly during the follow- up period.
Objective: We have utilized subclavian flap angioplasty (SFA) frequently in infants with coarctation particularly in patients with arch hypoplasia which is quite frequent.
