CHIESA, PEDRO et al. Cierre de la comunicación interauricular con dispositivo oclusor implantado mediante cateterismo cardíaco. Rev.Urug.Cardiol. [online]. 2004, vol.19, n.2-3, pp.73-80. ISSN 1688-0420.

SUMMARY Since King and Miller’s publication in 1974, it has been demonstrated that certain atrial septal defects can be closed by percutaneous technique. Many devices have been developed with that purpose. It has been a major challenge for medical bioengineers to design the ideal one. A total of 30 patients with ostium secundum type atrial septal defects were attempted to close (ages 16 months to 35 years, minimum weight 8,5 kg.). A Cardioseal device was utilized in 3 cases, an Amplatzer in the other 27. In 3 patients the percutaneous closure was not possible because of anatomical features. Both devices were removed without complications, before their release. In 27 patients, the defect was completely closed, there was one case with residual mild mitral insufficiency that disappeared in 3 months. In all of the procedures, simultaneous transesophageal echocardiography was utilized. The patients were discharged home a medium of 18 hours after the procedure. They received peri-procedural antibiotic coverage. Antiplatelet treatment with aspirin was maintained for 6 months. In conclusion, atrial septal defects closure with percutaneous implantable devices is a simple and practical procedure, with excellent results, and much less stressful hospital experience in comparison with heart surgery.
