Regarding operative mortality, EuroSCORE II showed in this study a slightly higher discriminatory accuracy than EuroSCORE I. There were no significant differences in the calibration of the two model versions in "low-" and "moderate-risk" patients regarding early as well as mid-term mortality. Analyses in larger patient populations will contribute to further model improvement.

Considering the severity of the onset, a radical surgical treatment delivers acceptable long-term results by acceptable operative mortality. The choice of the prosthetic device seems not to be influential in long-term survival and morbidity.

In the patient cohort investigated there is in general no need for restrictive use of the ITA in CABG.

Sorin Bicarbon prosthesis provides excellent clinical results and mid-term survival with very low complication rates comparable with those of other bileaflet prostheses currently in use.
