Coronary embolism following atrial septal defect repair.

To our knowledge, coronary embolism following repair of atrial septal defect has not been reported previously. A 29-year-old woman had an angiographically documented embolus to the circumflex coronary artery on the fifth postoperative day after pericardial patch repair of a secundum atrial septal defect. This complication might have been prevented by temporary postoperative anticoagulation.
