Aortocoronary bypass graft fistula after surgical treatment of circumflex coronary artery fistula: a unique variation of a rare condition successfully treated with percutaneous embolization.

Multiple coronary artery fistulae are rare, complications can be life-threatening, and with large or symptomatic fistulae, intervention is mandatory. Both surgical and percutaneous interventions are well-described. We believe this is the first report of the embolization of an acquired fistula following initial surgical treatment of multiple congenital fistulae.
