title: Transcatheter closure of coronary artery fistulae: initial human experience with the Amplatzer Duct Occluder II.
abstract: OBJECTIVE
  To evaluate the efficacy and safety of the new device Amplatzer Duct Occluder II (ADO II) for the closure of coronary artery fistulae (CAF) with coronary anomaly.
  
  
  BACKGROUND
  Transcatheter device closure is an alternative treatment for selective patients with CAF. The currently available reports regarding the closure of CAF with the ADO II are limited.
  
  
  METHODS
  From April 1, 2011 to July 15, 2012, 5 patients (3 males and 2 females) aged from 3 years to 27 years old (median age 5 years old) underwent CAF closure with the ADO II. The immediate and short-term outcomes were evaluated.
  
  
  RESULTS
  ADO II was deployed via the femoral vein (2 cases), femoral artery (1 case), brachial artery (1 case), and radial artery (1 case). There were no complications during all the procedures. The median fluoroscopy and procedural times were 20 and 39 minutes, respectively. Immediate trivial and mild residual shunt was present in one patient, respectively, but disappeared 24 hours after the procedure, and there was no recanalization at a median follow-up of 6 months.
  
  
  CONCLUSIONS
  The new device ADO II was safely deployed with complete resolution of CAF shunt with tortuous coronary artery to the drainage. The reduced sheath sizes and softer shape of this device allow for venous or arterial approach. The ADO II might be a preferable alternative device for closure of small-tortuous CAFs.
