Coronary arteriovenous fistulas and coronary cameral fistulas are rare anomalies that involve the abnormal communication between a coronary artery and a venous structure, such as a coronary vein or a right-sided cardiac chamber. Iatrogenic coronary arteriovenous fistulas and coronary cameral fistulas can be uncommon complications of coronary artery angiography and intervention. Acquired coronary arteriovenous fistulas that develop during percutaneous coronary intervention of chronic total occlusions have been previously reported in the literature. However, a coronary arteriovenous fistula resulting from contrast injection into a chronically and totally occluded right coronary artery during diagnostic coronary angiography is very rare. We present a unique case of a contrast-induced iatrogenic right coronary dissection leading to a coronary arteriovenous fistula communicating to the right atrium through the middle cardiac vein.
