Fenestration closure in a patient who underwent extracardiac type Fontan operation with a short conduit (A) as a fenestration. An angiogram shows the flow through this short conduit (B, arrow). There is small shunt on an angiogram (D) after the first coil detachment (C). Therefore we put the second (E) and the third coil (F) one by one. There is no significant residual fenestration flow after insertion of three coils (G).
