The study endpoints analysed the correlation between the number and types of grafts with the survival time following isolated CABG surgery.Results: The total arterial revascularization (Group A) group had an admirable mean long-term survival of ~19 years, compared to 18.6 years (Group B), 15.86 years (Group C), and 10.99 years (Group D). A Kaplan-Meier curve demonstrated confidence interval (CI) for study groups- (95% CI 18.33– 19.94), (95% CI 18.14– 19.06), (95% CI 15.40– 16.32), and (95% CI 9.61– 12.38) in Group A, B, C, D respectively. In the Holm-Sidak method analysis, significant associations existed between the number of arterial grafts and the long-term outcome. A statistically significant (P≤ 0.05) long-term survival advantage for arterial grafting was demonstrated, especially total arterial revascularisation over all other combinations except single internal mammary artery + radial artery grafting.Conclusion: In this series, over 20 years, total arterial CABG use has excellent long-term survival, achieving complete myocardial revascularisation. There is no significant difference between the BIMA group and SIMA with radial artery. However, there is a reduced survival with decreased use of arterial conduits.Keywords: coronary artery bypass graft, CABG, bilateral internal mammary artery, total arterial CABG, long term outcome, multiple arterial graft, mortality, survival benefits
