Abstract:
We reported a 74-year-old female complicated by ostial obstruction of the left main trunk after aortic valve replacement for severe aortic stenosis. At surgery, the length from the orifice of the left main trunk to the aortic annulus was 3 mm. After a 19 mm Carpentier-Edwards PERIMOUNT MAGNA was implanted in supra-annular position, the orifice of left main trunk was concealed by a sewing cuff of the bioprosthesis. Before aortic declamping, saphenous vein graft was bypassed to the left anterior descending artery. The postoperative course was uneventful. Computed tomography demonstrated the ostial obstruction of the left main trunk by the bioprosthesis.
