This is a retrospective study looking at 2,768,007 Medicare beneficiaries in the US undergoing myocardial revascularization between 2008 and 2012. From a surgical point of view it is interesting to see that the proportion of CABG among all revascularization procedures declined from 24.8% in 2008 to 23.2% in 2012. The number of centers performing less than 100 CABG procedures per year increased from 23.4% of the total number of centers performing CABG in 2008 to 29.5% in 2012, and the proportion of centers performing more than 500 CABG procedures per year declined from 5.1% in 2008 to 3.2% in 2012. In hospital mortality for isolated CABG varied between 2.27 and 2.56%.
