Right coronary artery arises directly from a coronary artery fistula
Right coronary artery follows an anomalous retroaortic course
Correct! The correct answer is "Right coronary artery arises directly from a coronary artery fistula".
 
The CT coronary angiogram revealed a coronary artery fistula between the right coronary cusp and the posterior aspect of the superior vena cava with a tortuous fistulous vessel measuring up to 1.5 cm in size between the aortic root, right atrial appendage and SVC. Mid right coronary artery arises directly from the fistula. No significant disease within the right coronary artery.

 
Good try! The correct answer is "Right coronary artery arises directly from a coronary artery fistula".
