What is the course of this anomalous vessel and name of the sign?
Retroaortic course posterior to the aortic root with the “posterior dot sign.”
Interarterial course between the aorta and pulmonary artery with the “anterior dot sign.”
Intraseptal (transseptal/subpulmonic) course through the interventricular septum with the classic “eye sign”, the left main forming the inferior limbus of the “eye”
Correct! The correct answer is "Intraseptal (transseptal/subpulmonic) course through the interventricular septum with the classic “eye sign”, the left main forming the inferior limbus of the “eye”".
 
When the left main comes from the wrong sinus, the ‘dot-and-eye sign’ tells you where it travels and helps differentiate the potentially malignant interarterial course from generally benign variants.
 
An anomalous left main arising from the right coronary cusp may follow four possible courses. The RAO projection often helps identify the pathway using the classic “dot-and-eye sign.” A retroaortic course shows a posterior dot sign, whereas an interarterial course shows an anterior dot sign. In the present case, the “eye sign” is formed by the left main constituting the inferior limb and the LCx the superior limb of the eye.
 
Septal perforators arising from the left main is another clue that further supports transseptal (intraseptal) course.
