Transcatheter closure of coronary artery fistula in children
作者单位: 
摘    要:Background Transcatheter closure of coronary artery fistula (CAF) has emerged as a successful alternative to surgery. We described our experiences in 10 children patients who were accepted for transcatheter closure of CAF. Methods Ten children were 3-10 years old (seven males) with CAF who underwent percutaneous transcatheter closure between October 1995 and April 2008. Sites of origin of these fistulas were: right coronary artery in seven, left anterior descending coronary artery in two, and left circumflex coronary artery in one patient. Drainage sites of these fistulas were: right atrium in seven, right ventricle in two and left ventricle in one patient. All of these fistulas were congenital and had only one orificium fistula.Results A Cook coil was used in four patients and an Amplatzer patent ductus arteriosus (PDA) occluder was used in six patients. Checking the angiogram after the procedure revealed complete occlusion in nine patients (90%) and minimal residual flow in one (10%) patient. Technical success was achieved in all patients. Follow-up studies at short term showed complete abolition of shunt in all patients with no evidence of recanalization leading to recurrence of shunt. Conclusions Transcatheter therapy using either Cook coil or Amplatzer PDA occluder is suggested to be a safe and effective method of occlusion. The midterm outcome of the intervention for CAF is satisfactory.
