Feasibility and safety of transcatheter closure of ventricular septal defects in 184 children under 3 years old.

??Abstract??Objective To evaluate the clinical effect of transcatheter closure for ventricular septal defect in infants and young children. Methods Clinical data from 184 children under 3 years old who underwent the transcatheter VSD closure from Jan. 2011 to Dec. 2012 were analyzed. Results Procedure was successful in 176 cases ??95.7%??. No death occurred?? residual shunt in 13 cases?? tricuspid inflow accelerated in 2 cases?? late-onset complete atriovenous block in one case ??6 months after procedure??. All cases had no vascular complications. Conclusion Transcatheter closures for ventricular septal defects are effective in small children. Long-term follow-up is needed to evaluate the safety of this operation. The keys to the success of operation are the proper indications,suitable apparatus,skillful vascular punction and good anaesthetic management.
