[Transcatheter closure of congenital ventricular septal defects].

We report on the transcatheter closure of ventricular septal defects (VSD) in 26 patients with Amplatzer Occluders and Nit- Occlud Coil Systems. Twenty-one patients had a perimembranous and 5 patients a muscular VSD. Patients' age range was 5 months to 59 years (median 8 years) and their body weight 4.5 kg to 167 kg (median 28 kg). Defect diameters were 3-11 mm (median 5 mm). Sixteen patients had left ventricular volume overload and 7 patients pulmonary hypertension (median 50% of systemic pressure). Seven patients suffered from trivial or mild aortic regurgitation. Twenty-eight devices (4-12 mm; median 8 mm) were implanted (16 Amplatzer, 12 Nit-Occlud) through sheaths of 4F to 9F (median 7F). Fluoroscopy times were 8.3- 56.5 min (median 26.2 min). One coil was surgically explanted directly after intervention. One patient needed pulmonary banding due to additional VSDs. After a follow-up of 7 months (1-12 months), 2 patients had a small and 9 a minimal residual shunt. Thirteen defects were completely closed. Transcatheter closure of VSDs with new devices seems to be a promising therapy for suitable defects in different hemodynamic conditions in patients of every age.
