摘　　要：Background:Limited data are available regarding intermediate and long-term outcomes of transcatheter closure(TCC)of coronary cameral fistulas(CCFs)in the pediatric patients.Methods:All pediatric patients diagnosed with CCFs who were scheduled to undergo TCC between 2005 and 2019 were retrospectively enrolled in the study.Results:A total of 66 patients(median age:3.93 years,median weight:15 kg)underwent attempted TCC of CCFs.Immediate successful device implantation was achieved in 62 patients,and immediate complete occlusion was achieved in 44 patients(44/62%,71.0%).The closure procedure was waived in 2 patients due to anatomical factors.A total of 6 periprocedural complications occurred in 5 patients,including acute myocardial infarction(n=3),procedure-related death(n=1),device embolization(n=1),and rupture of tricuspid chordae tendineae(n=1).The acute procedural success rate was 89.4%(59/66),while the acute complication rate was 9.1%(6/66).Follow-up data were collected for 58(93.5%)out of 62 patients at a median of 9.3 years(range:3.0–15.7 years).10 adverse events occurred in 9 patients,including 5 follow-up complications(1 aortic valve perforation,1 coronary thrombosis,1 progressive aneurysmal dilation after reintervention,and 2 cases of new-onset tricuspid valve prolapse with significant regurgitation),and 5 closure failure with large residual shunts.The intermediate and long-term adverse event rate was 17.2%(10/58).The anatomical features associated with both acute and follow-up adverse events were large CCFs(p=0.005),and giant coronary artery aneurysms(CAAs)(p=0.029).Conclusions:TCC of CCFs in infants and children appears to be effective and is associated with a relatively low complication rate.Large CCFs and giant CAAs represent a higher risk of both acute and intermediate and long-term adverse events after closure.
