title: [Surgical osteoplasty of the left main coronary artery using the right internal thoracic artery].
abstract: A 39-year-old female with a history of progressive refractory angina required medical treatment. A coronary angiography showed 75% left coronary ostial stenosis without any other atherosclerotic lesions. The isolated ostial stenosis of the left main coronary artery was reconstructed by patch angioplasty, using a proximal segment of the right internal thoracic artery. The transaortic patch angioplasty was performed using a superior approach, which allowed a good exposure of the left coronary artery to the aorta without difficulty. A postoperative coronary angiography showed satisfactory patency, and a small biopsy of the ostial tissue demonstrated findings compatible with fibromuscular dysplasia. Based on this outcome, a proximal segment of the internal thoracic artery appears to provide a suitable patch material for enlarging the left coronary ostium.
