title: Regression of left main coronary ostium stenosis after surgical revascularization and steroid therapy.
abstract: We describe a patient in whom stenosis of the left main coronary ostium completely regressed after steroid treatment following surgical revascularization. A 46-year-old woman with unstable angina underwent double coronary artery bypass grafting. Although she did not fulfill diagnostic criteria for Takayasu's disease, we began postoperative steroid therapy on postoperative day 14 based on clinical manifestations and histological findings. Coronary angiography 33 days after surgery showed the ostial stenosis of the left main coronary artery had disappeared. Steroid therapy for suspected Takayasu's disease should be considered even after surgical revascularization.
