AbstractIatrogenic aortic injury occurring during either coronary bypass grafting or valve replacement is a well‐recognized complication of cardiac surgery. We retrospectively reviewed our experience and found 11 cases occurring in a case load of 8,945 hearts (incidence of 0.12%). All 11 cases were repaired, with 10 patients surviving. The type of repair used usually was determined by when the diagnosis was made. When an intraoperative diagnosis was made, a local repair was done in four of six cases. If a postoperative diagnosis was made, then all five patients needed the ascending aorta replaced. With early diagnosis and rapid repair, good surgical results can be achieve
