3.3.2. Occluder devices
A considerable amount of literature has been discussed and analyzed the device for TCC of a PIVSD. The most commonly used occlude devices are as follows: atrial-septal-defect occluder (ASDo, 118/355, 33.2%), muscular ventricular-septal-occluder (mVSDo, 96/355, 27.0%) and a specific post-infarction mVSDo occluder (PimVSDo, 131/355, 36.9%) which is specifically designed for the PIVSD. There was minority studies used device(10/355, 2.8%): patent ductus arteriosus occluder[10] (PDAo,3/10,0.3%), Amplatzer cribriform occluder[13] (ACO,2/10,0.2%), modified double-disc occluder[14](3/10.0.3%) and other device[15](2/10,0.2%).
