Abstract：Objective To investigate the early and medium-term effect of transcatheter closure (TCC)of congenital coronary artery fistulae (CAF)by using Amplatzer vascular plug (AVP)in children and the occurrence of postoperative complications.Methods Preoperative,imaging,and postoperative follow-up data were collected from 7 patients treated with transcatheter closure of CAFs using AVPⅠ or AVPⅡ,and then we analyzed the relationships between the clinical effi-cacy,postoperative complications and closure way,anticoagulation.Results Seven cases all underwent successful TCC with 1 case of AVPI and 6 cases of AVP Ⅱ.A no-residual-shunt rate was 71.4% (5 /7)right after deploying devices.The period of postoperative follow-up was 4-36 months.Postoperative C /T ratio and diameter of right ventricle were less than the baseline levels (all P <0.05).All EF% was in normal range postoperatively.Of 7 cases,3 took aspirin for 6 months after TCC,2 for 3 months,1 for 3 days,and 1 did not take any.In 1 case a move of the device was noticed with a prominent re-sidual shunt,which reduced gradually after discontinuance of aspirin therapy.In another case a prominent residual shunt was found but no improvement after discontinuance of medication,resulting in another TCC by coils.In all cases no throm-botic or embolic event was found.Conclusions TCC by AVPⅠ /AVPⅡ in children can reduced shunting and relieve symptoms.Residual shunt and migration of device may be its common complications.We should consider the residual shunt in postoperative anticoagulating or antiplatelet therapy.
