Ectasia and Aneurysm of the Right Coronary Artery Resulting From a Shunt to the Coronary Sinus
A 65-year-old woman presented with a systolic-diastolic murmur. Further MRI investigations as well as angiography revealed an arteriovenous shunt to the coronary sinus via an enlarged right coronary artery (Figure 1A⇓ and 1B⇓). The distal part of this coronary artery was transformed to a large coronary aneurysm of such extent that the left atrium was compressed (Figure 2A⇓ and 2B⇓). The coronary sinus was imaged by angiography of the aorta before the coronary aneurysm was filled with dye. We hypothesize that these changes are due to a congenital shunt to the coronary sinus.
