Abstract:
Iatrogenic intraoperative coronary artery ostial occlusion is quite rare and a dangerous complication of aortic valve replacement. Intraoperative vigilance and prompt intervention are required to manage this fatal complication. A case report of a 48-year-old female with normal coronaries who underwent aortic valve replacement and had right ventricle distension is described here. It seemed that the cause which led to right coronary ostial obstruction was due to prosthesis aortic root mismatch and it required bypass with a vein graft. Computed tomographic angiography of aortic root showed abutting of right coronary ostium by the aortic valve prosthesis.
