CTICasesCoronary Artery to Coronary Sinus Shunt

Imaging findings
Gated CT shows a large, dilated right coronary artery originating normally, which then loops around the heart in the atrioventricular groove and dumps into the coronary sinus. The left coronary system appears healthy.
Key takeaways
A significantly dilated coronary artery often indicates a shunt. This finding in an 85-year-old patient suggests an acquired etiology, potentially causing coronary steal syndrome, presenting with chest pain. These are not typically congenital in this age group.
