Abstract:
A 78-year-old man presented with chest pain and ST segment elevation. Coronary angiography showed no significant coronary artery disease. A saccular pocket of contrast material was found outside of the distal right posterior descending coronary artery consistent with a pseudoaneurysm. Echocardiography showed a pocket of pericardial fluid behind the left atrium concerning for a hemopericardium. The pseudoaneurysm was treated urgently with two coils successfully deployed to obtain complete exclusion of the pseudoaneurysm sac and occlusion of the distal portion of the posterior descending coronary artery.
