We present the case of a 67‐year‐old man in whom a guidewire broke at rotablation of the right coronary artery, creating an iatrogenic aneurysmal arteriovenous fistula to the coronary sinus. Successful Doppler wire‐guided fistula occlusion by percutaneous coil embolization lead to normalization of coronary blood flow and relief of the patient's symptoms. Myocardial ischemia in this patient may have been due to a steal phenomenon caused by coronary artery fistulae, as suggested by blood flow velocity data obtained before and after fistula occlusion.
