An important finding of the current study is that in terms of the 10-year survival redo-OPCAB is as effective as conventional redo-CABG across all the 3 analyses undertaken. This finding is reassuring when considering the technical complexity involved in undertaking coronary anastomoses on the beating heart within the context of a redo cardiac procedure. This finding is in keeping with the long-term outcome of our previous BHACAS trial reporting on long-term graft patency and survival following primary OPCAB surgery [14].
