Risk prediction models are important tools for assessing quality of care and facilitating medical decision making. The majority of cardiac operations are CABG surgery or heart valve surgery, and about one third of surgical valve procedures are performed concomitantly with CABG surgery. Isolated CABG surgery dominates the field of surgical risk models; models for valve surgery are less common. One reason is that valve operations are less frequent than CABG procedures. Another reason is that valve operations are complex and can involve multiple valve positions, many concomitant procedures and can be associated with more heterogeneous disease processes. Since the number of surgical heart valve procedures is increasing over time, valve surgery risk models are becoming increasingly important.
