Conclusion Transcatheter closure of VSDs in various locations can be safely and effectively carried out using the Amplatzer occluders Transcatheter closure of VSDs in various locations can be safely and effectively carried out using the Amplatzer occluders Results are encouraging. Muscular defects comparable to surgery; perimembranous marginally less good than surgery. Post-infarct still carry high risk but better results than surgery Results are encouraging.
