title: Successful coil embolization with assistance of coronary stenting in an adult patient with a huge coronary arterial-right atrial fistula.
abstract: A 55 year-old man with huge coronary artery fistula to the right atrium is presented. The Qp/Qs ratio was 1.6. We failed to place simultaneously three interlocking detachable coils for closing the fistula, because the coils were washed out into the right atrium. We deployed the coronary stent at the distal portion of the coronary artery. This procedure enabled us to anchor 7 electrically or interlocking detachable coils and to interrupt the shunt flow. A Doppler flow wire was useful to reveal instantaneously the extent of flow reduction even when contrast angiography was not performed in each procedure.
