Dilated cardiomyopathy caused by a coronary-pulmonary fistula treated successfully with coil embolization.

We describe a case of dilated cardiomyopathy (DCM) caused by a coronary-pulmonary fistula and myocardial ischemia induced by the coronary steal phenomenon, which was successfully treated with coil embolization. Coronary fistulae and coronary-steal-induced ischemia are rare causes of DCM in adults with normal coronary arteries. Percutaneous treatment represents an alternative to surgery and may be offered as a relatively low-risk procedure. The choice between surgical and percutaneous treatment must take into account clinical and anatomical considerations.
