Surgical repair of bilateral coronary artery fistulae and a left main coronary artery aneurysm following a failed percutaneous embolization

“…Coronary artery aneurysms (CAA) may involve all branches of the coronary artery vasculature including the left main coronary artery (LMCA), and may require transection of the aorta and pulmonary artery (PA) for exposure to perform the repair. [1][2][3][4] In addition to rupture, CAAs may also fistulize to other structures including the PA 5,6 and left ventricle. 7 Although percutaneous coils have been used to occlude coronary artery fistulas (CAF), 8 surgery remains the definitive therapy for CAF associated with CAAs.…”

Giant circumflex coronary artery aneurysm presenting as an intra-pericardial mass

“…Coronary artery aneurysms (CAA) may present with unstable angina, fistulae to the pulmonary artery, and left ventricle, and may mimic pericardial tamponade or a pericardial mass . We present images of a CAA presenting as an inta‐pericardial mass.…”
