[Catheter treatment of congenital heart defects. Arterial septal defects and open ductus arteriosus].
The results of new methods for catheter treatment of congenital heart defects are presented. Between 1989 and 1996 closure of a patent ductus arteriosus was performed in 66 instances on 63 patients, eight of which were with coils. Three patients were treated twice, one with an additional umbrella, two with coils. The overall complete closure rate for umbrellas was 75%, after two ducts, which were initially totally occluded, recanalized. In six more patients the procedure was either aborted or indication was not present. All six ducts treated with coils as the first procedure were completely closed. One of two patients who had residual leak after previous umbrella treatment achieved complete closure after subsequent coil implantation. Closure of atrial septal defects in the oval fossa was performed using the Amplatzer septal occluder in seven children. Complete closure was achieved in all of them. There have been no complications, in particular there have been no cases of embolization in any of the groups. The results seem to indicate that coil occlusion of a persistently patent duct may be at least as good as the umbrella in terms of complete closure. So far both methods have been safe, but experience with coils is limited. The closure of atrial septal defects shows encouraging results. We will continue to offer this treatment as an alternative to open heart surgery in carefully selected patients.
