Fig 1 Previous procedure type as a univariate risk factor for in-hospital mortality after redo cardiac procedures. (AV = isolated aortic valve operations; CABG = isolated coronary artery bypass grafting; CABG + Other = CABG in combination with any other cardiac procedures; MV = isolated mitral valve operations; n = number of patients in each group; Other = any cardiac surgical procedure requiring sternotomy that was not included in the other categories; Other Valve = any valve operation other than isolated aortic valve procedures or isolated mitral valve procedures, with or without a concomitant procedure that was not CABG.)
