Dyspnea and a Fistula: A Case Report of an Unusual Cardiac Connection

Coronary cameral fistulas are rare abnormal connections between one or more coronary arteries and any chamber of the heart, occurring in less than 1% of the population. Cameral fistulas are classically asymptomatic and an incidental finding. Etiology is most commonly congenital but can also be acquired secondary to cardiac surgery or trauma. Cardiac catheterization with coronary angiography remains the diagnostic modality of choice. We present a case of a symptomatic patient presenting with dyspnea and hypertension diagnosed with an incidental mid‐left anterior descending to right ventricle cameral coronary fistula. We discuss current literature on the management of this anatomic anomaly.
