Summarized patient outcomes/complications of amplatzer duct occluder ii were reported in a research article in a subject population with coronary cameral fistula and coronary artery aneurysm.Some of the complications reported were thrombus, obstruction, myocardial infraction and surgical intervention; these complications are anticipated for the procedure and subject population.Information from field indicated that a decision was made to explant the device via transcatheter snare and thrombus was aspirated from the patient.A more comprehensive assessment could not be performed as the event was non-contemporaneously reported through a literature review and no device or individual patient information was received for analysis.Please note that per the instructions for use, "indications and usage: the amplatzer¿ duct occluder ii is a percutaneous transcatheter occlusion device intended for the non-surgical closure of patent ductus arteriosus.".

The article, ¿intermediate and long-term follow-up of transcatheter closure of congenital coronary cameral fistulas in infants and children: experience from a single center¿, was reviewed.The article presented a case study of a 1.25-year-old, 12kg patient with a coronary cameral fistula and coronary artery aneurysm.It was reported that on an unknown date, a 5-6mm amplatzer duct occluder ii was chosen for implant to occlude a coronary cameral fistula.After release of the device, complete right coronary artery (rca) occlusion occurred and thrombus was detected within the occluded rca.Acute inferior myocardial infarction was confirmed by twelve-lead electrocardiography (ecg).A decision was made to explant the device via transcatheter snare and thrombus was aspirated from the patient.The patient was discharged on heparin for three days followed by dual anti-platelet therapy with aspirin and clopidogrel for one month.It was reported another transcatheter closure was planned at an unknown date.The article concluded that tcc of ccfs in infants and children appears to be effective and is associated with a relatively low complication rate.Large ccfs and giant coronary artery aneurysms (caas) represent a higher risk of both acute and intermediate and long-term adverse events after closure.[the primary and corresponding author was zhiwei zhang, department of pediatric cardiology, guangdong cardiovascular institute, guangdong provincial people¿s hospital (guangdong academy of medical sciences), southern medical university, guangdong provincial key laboratory of south china structural heart disease, guangzhou, 510100, china, with corresponding email: drzhangzw@sohu.Com].
