Coronary fistula is an abnormality characterized by abnormal communication between a coronary artery and a cardiac chamber or large vessel. Half of fistulas originate from the right coronary artery, 45% from the left coronary artery, and less than 5% originate from both. We present an 81-year-old female patient with a history of previous ischemic stroke, who was admitted with a new cerebral ischemic event. In complementary studies, a reduced ejection fraction of the left ventricle was documented, then arteriography was performed showing epicardial coronary arteries without significant obstructive disease, but with coronary-pulmonary fistula in the middle segment of the anterior descending artery and a coronary-pulmonary fistula in the proximal segment of the right coronary artery. Coronary fistulas are a rare entity, with nonspecific symptoms. Most of the time this entity is diagnosed incidentally when performing a coronary arteriography for another reason. Management varies according to the manifestations and anatomy found along with the experience of the cardiology team.
