“…The incidence of coronary artery fistula is 0.1% to 0.2% in all patients undergoing coronary angiography [ 4 ]. CCF may be single or multiple and occur between one or more coronary arteries, bypassing the myocardial capillary bed [ 5 ]. During early fetal development, sinusoids nourish the primitive myocardium, which is connected to the primitive tubular heart.…”

“…Several diseases, such as coronary vasculitis and myocardial infarction, can also lead to coronary arterial fistulae during the chronic phases [ 6 ]. CCF commonly originate from the right coronary artery (55%) but can also originate from the left coronary artery (35%) or bilaterally (5%) [ 5 ]. CCF most commonly terminate in the RV (41%), followed by the right atrium (26%) and the left atrium and LV (3%-5%).…”

“…Patients can present with syncopal episode [ 11 ]. Other complications associated with CCF include aneurysmal formation, pericardial effusion, cardiac failure, atrial fibrillation, supraventricular and ventricular arrhythmias, bacterial endocarditis, thrombosis and/or embolism, rupture causing hemopericardium, sudden cardiac death, valvular regurgitation due to papillary muscle abnormality, and premature atherosclerosis [ 5 - 6 , 8 ].…”

Coronary-cameral fistulae (CCF) are rare, frequently incidental findings uncommonly noted during routine coronary angiography. They are nearly always congenital and are sometimes associated with other cardiac malformations. They can also be acquired due to trauma or chronic inflammation. These fistulae most commonly originate from the right coronary artery. The site of termination is usually the right ventricle (RV) and rarely the left ventricle (LV). Though nearly always asymptomatic and clinically insignificant, depending on their size and pressure gradient between communicating sites and terminating area, CCF can lead to pulmonary hypertension, LV dysfunction, and myocardial infarction. We describe the case of a 55-year-old woman who presented with worsening dyspnea and lower extremity edema. Transthoracic echocardiography demonstrated an ejection fraction of 55% with an RV systolic pressure of 67 mmHg. Right heart catheterization was performed to formally diagnose pulmonary hypertension and left heart catheterization was performed concurrently. This demonstrated a fistula between the first obtuse marginal branch of the left circumflex artery to the LV cavity. In this report, the authors provide a brief review of the presentation, diagnosis, complications, and management of CCF.

“…They rarely terminate into the left ventricle or pericardium. Fistulae are classified as either arterioluminal (direct communication with the cardiac chamber) or arteriosinusoidal (communication via the sinusoidal network) [ 2 ]. Historically, they were usually diagnosed via coronary angiogram, but with the advances in noninvasive cardiac imaging, they are being increasingly seen in coronary CT imaging [ 4 , 5 ].…”

“…Coronary artery anomalies include various congenital disorders whose manifestations and pathophysiological mechanisms can be highly variable. Coronary-cameral fistulae (CCF) are congenital or acquired anomalous communications that occur between coronary arteries and a cardiac chamber [ 1 , 2 ]. Acquired CCF are usually associated with trauma or prior cardiac surgeries.…”

Coronary-Cameral Fistula, Thebesian Veins, and Anomalous Coronary Vein on Cardiac Computed Tomography

A 63-year-old female with a history of hypertension presented with progressively worsening shortness of breath. She underwent a cardiac catheterization and was found to have prominent Thebesian veins as well as anomalous connections between the proximal right coronary artery and the right ventricle. Cardiac computed tomography was ordered for further evaluation and showed a coronary fistula to the right ventricular outflow tract confirming the diagnosis of a coronary-cameral fistula (CCF). CCF are rare congenital anomalous communications that occur between coronary arteries and a cardiac chamber. They are usually an incidental finding and patients are rarely symptomatic. As the use of coronary computed tomography angiography is rapidly expanding, the detection of CCF will likely increase in the general population.

Key Clinical MessageDual coronary cameral fistulae (CCFs) are rare abnormal connections between coronary arteries and heart chambers. Management of CCFs remains a topic of debate, emphasizing the need for individualized approach based on presentation.AbstractWe present a rare case of dual coronary cameral fistulae originating from the mid‐left anterior descending (LAD) and the mid‐right coronary artery (RCA) with drainage into the left ventricle, diagnosed incidentally during coronary angiography.
