Journal article 4 The study aimed to determine the in-hospital health outcomes and patient survival in 10 year period for those undergoing the redo coronary surgery with (redo- CABG) or without (redo-OPCAB) cardiopulmonary bypass.  Reducing the risk of morbidity and mortality and improving the quality of life in patients undergoing cardiac or coronary surgery, would indicate the method that is most beneficial and is associated with less incidence of complications. The researchers identified  349 redo coronary surgery patients from the UK National Registry, whereby there were 143 redo-OPCAB patients (40.97%), which is the conventional method, and  206 redo-CABG patients (59.03%),   and the later was the control group. These patients underwent surgery from May 1996 to January 2014 This was a retrospective single-center analysis approach comparing conventional redo-CABG with the redo-OPCAB cohort. The study was also anonymous as the researchers did not know the identity of the patients and comparing patient outcomes between the two groups helps to determine, which approach to use for the patient in different physical conditions.  Previous research on the OPCAB for redo coronary surgery has mainly focused on small cohorts, and there are few types of research to compare with, but they seem to indicate that the techniques associated with lower mortality and fewer day in hospitals. The researchers focused on both matched and unmatched analysis, and in the unmatched analysis, there were less of diseased coronary vessels.   For the redo-OPCA group,  the in-hospital mortality rate was 2.8 times higher for the redo CABG patients.  Nonetheless, the long-term survival rate was similar for both groups. In case of Matched Analysis A where there 111 pates in each group with patients having undergone surgery for CABG only, valve as well as CABG and the value with or without the other [4]. There was higher reopening for bleeding for the redo-CBG group at 4% compared to 1% for the other group p=0.17) [4]. As there was less need for intra-aortic balloon pumping, the redo-OPCAB group at 2% versus 10% and lower in-hospital mortality, redo-OPCAB is feasible to improve hospital survival and health outcomes [4]. The study was conducted in a single center, and there is a need for more research and evidence to identify the risk factor associated with redoes valve surgery to inform surgical decision-making and improve the quality of life. Redo-OPCAB can be conducted safely, has similar and at times outcomes that redo- CABG) and ought to be considered in cardiac surgery Journal article 5 The purpose of the study was ...
