"The most common origins for the CAVF are the RCA (50%) and LAD (42%) while the most common drainage sites are the relatively low-pressure right ventricle (41%), right atrium (26%), or pulmonary artery (17%) 3,4. However, any coronary artery may be an origin and the fistula may less commonly drain into the coronary sinus, superior vena cava, or left-sided cardiac chambers 3,4."
"They can be classified according to their origin, drainage site, or complexity; the number of fistulous tracts; or the presence of accompanying anomalies."

"Coronary artery angiography is an invasive imaging modality for evaluating CAVFs and has long been considered to be the gold standard 3,4,6,7. Angiography is able to provide details regarding the origin, drainage, size, and course of CAVFs 3,4,6,7."
