This 10-year follow-up of the ROBY study reports on the primary end points of all-cause death and the composite of death or revascularization among 2203 patients randomized to off-pump or on-pump CABG 2002-2007.  Death rates at 10 years were 34.2% for off-pump and 31.1% for on-pump.  The composite end point was reached at 4.6 years for off-pump and 5.0 years for on-pump.  The study identified no advantages for off-pump bypass related to these 10-year outcomes.


This paper will be hotly debated in years to come. The logical assumption is that ALL the surgeons involved were EQUALLY PROFICIENT to BOTH interventions....
