TODO - The efficacy and safety of the transcatheter patch (TP) correction of a
secundum atrial septal defect (ASD) was studied acutely and on
short-term follow-up in 20 patients, successfully implanted with the
device. TPs are made of polyurethane foam and require temporary balloon
catheter immobilization on the atrial septum for 48 hours. Eighteen
patients were not suitable for disk-device repair. The patient median
age and ASD diameter were 37 years and 26 mm, respectively. Eighteen
patients had immediate effective ASD occlusion; 2 patients had
significant residual shunts. Premature leaks of the supportive balloons
were responsible for the residual shunts. One of the patients with
residual shunt received a second patch 6 months later with full
occlusion. All patients with implants were doing well up to 24 months
after implantation. Existing symptoms improved although residual shunts
remained; septal anatomy was normalized, with the patched area becoming
progressively indistinguishable from the rest of the septum. in
conclusion, TP occlusion of secundum ASD is feasible and effective even
for defects unsuitable for disk-device repair. The method appears safe
acutely and on short-term follow-up, with symptomatic improvement and
normalization of septal anatomy. (C) 2002 by Excerpta Medica, Inc.
