RESUMEN
Ventricular septal defect [VSD] accounts for approximately 20% of all forms of congenital heart disease. The conventional treatment has been the surgical closure of these defects. Percutaneous closure of VSD had been attempted in the past but it was not until the development of Amplatzer Muscular VSD occluder device that the higher closure rates and safety of the procedure made it an attractive alternative to the surgical closure. Amplatzer VSD devices have also been designed to close perimembranous and post infarction muscular VSDs and the results have been encouraging. In addition to the percutaneous conventional approach, an intraoperative [perventricular] technique has been developed to allow safe VSD closure with Amplatzer devices in small infants with poor vascular access avoiding the need of cardiopulmonary bypass or in infants with concomitant cardiac defects requiring surgical repair. In this review the transcatheter VSD closure with Amplatzer VSD occluders will be discussed for each type of VSD and the technical aspects will be detailed
