Most of these studies compared the predictive ability of the EuroSCORE to previously described systems2,3 or to locally derivedmodels.4 One original work used it as a tool in order to assess the intra-institutional benefit in switching from conventional surgery under cardiopulmonary bypass to the off-pump…
