Abstract
Coronary cameral fistula (CCF) is defined as an abnormal connection between the coronary artery and any cardiac chamber. It usually appears due to abnormal embryogenesis and represents less than 1% of the population. Most CCF cases are asymptomatic, however large CCFs may cause symptoms and complications. We present a case of a young female with symptomatic CCF suspected on echocardiography and confirmed by computed tomography coronary angiography. She was successfully treated surgically with total improvement of symptoms. LEARNING POINTS: Coronary cameral fistula (CCF) is an abnormal communication between the coronary arteries and cardiac chambers. Most fistulas are asymptomatic, however, large CCFs can cause symptoms.CCF can cause angina pectoris due to the coronary steal phenomenon, and may require surgical intervention.Coronary computed tomography angiography is a highly sensitive method for detecting coronary artery fistulas noninvasively.
