Abstract: | Although rare, iatrogenic coronary ostial stenosis is an important complication of aortic valve replacement and Bentall procedure. We report a 32-year-old male presenting an acute coronary syndrome post-Bentall procedure and the role of computed tomography in diagnosis and management of iatrogenic coronary ostial stenosis. Such occlusions are commonly identified in the left main coronary artery, but can develop in venous bypass grafts at anastomoses with Dacron aortic grafts. Cardiac computed tomography is valuable to exclude noncoronary causes of chest pain, assess ostial stenosis of manipulated arteries post reimplantation, and shed light on mechanisms and management of these lesions. |
