Coronary artery fistula with giant aneurysm and coronary stenosis treated by transcatheter embolization and stent

Coronary artery fistula (CAF) with giant aneurysm and accompanied by coronary artery stenosis is a very rare disease. Herein, we report a case of a 76-year-old woman having a complex coronary-to-pulmonary artery fistula associated with a giant aneurysm and accompanied by coronary artery stenosis. The patient was successfully treated using transcatheter coil embolization and coronary stent implantation. Eight years later, we performed a follow-up coronary angiogram, which revealed the CAF and the aneurysm were completely occluded and previous stent patency.
