* The number of patients received the certain type of devices. # One patient underwent transcatheter closure twice due to significant residual remained after the first closure. An 8-mm and 12-mm Amplatzer vascular plug I was used for the first and the second time of closure, respectively. † Three of 5 patients received 2 coils for one procedure. ‡ Three VortX-18 coils were used in this patient. § Residual shunt was detected immediately by angiograms after transcatheter closure or by echocardiograms one week after closure.
