This was not recognized because of its downward trajectory, and it was interpreted to be in the ascending aorta. Catheter manipulation perforated the right internal mammary artery, with development of pectoral hematoma. The perforation was sealed with coils and glue. (Level of Difficulty: Advanced.)
