What is the diagnosis?
Abnormally dilated and tortuous right coronary artery draining into the coronary sinus
Coronary artery aneurysm or ectasia
Mycotic coronary aneurysm in the context of infective endocarditis
Correct! The correct answer is "Abnormally dilated and tortuous right coronary artery draining into the coronary sinus".
 
Coronary artery fistulas (CAF) are rare. Angiography and CT confirm a dilated RCA draining into the coronary sinus. Normal stress imaging suggests symptoms from coronary steal or right-sided volume overload rather than ischaemia.

 
Good try! The correct answer is "Abnormally dilated and tortuous right coronary artery draining into the coronary sinus".
