Video Supplement to “Coronary-Cameral Fistula to Pulmonary Artery: An Innocent Bystander?” by Bhasin, et al (January 2021 Clinical Images).
Coronary-cameral fistula (CCF) is a rare congenital communication between a coronary artery and a cardiac chamber or a great vessel. Most patients are asymptomatic and these lesions are incidentally detected during coronary angiography, with the reported incidence being up to 0.2%. When large, these lesions can cause myocardial ischemia by causing coronary steal or high-output heart failure, and should be treated. We present an angiographic series demonstrating CCF in a 65-year-old man who presented to our emergency department with inferior-wall myocardial infarction.
