BACKGROUND: Percutaneous treatment of muscular ventricular septal defects (VSD) has been performed with good results in the last 10 years. We report our experience with the percutaneous closure of congenital muscular VSDs with Amplatzer devices assessing the feasibility, safety and efficacy of the procedure. METHODS: From 9/2002 to 12/ 2007, 9 procedures were performed in multiple centers in 8 non-consecutive patients (median age: 6 years; median weight: 26 kg) under general anesthesia and transesophageal echocardiographic monitoring. All VSDs were single (7 in the trabecular region and 1 anterior) and had a mean diameter of 6.0 ± 2.1 mm. There was one device embolization with immediate percutaneous device retrieval. This procedure was successfully repeated after a year. The other cases were completed successfully without major complications. The rate of complete closure was 100% at follow-up. CONCLUSION: In this small series of patients, percutaneous closure of congenital single muscular VSD was relatively easy to perform, safe and highly effective.
