Background. Multivessel coronary artery disease (CAD) and left ventricular dysfunction (LVD) present challenges in CABG. We aimed to compare early outcomes of total arterial revascularization (TAR) versus conventional CABG in this high-risk population. Methods. This was a retrospective cohort study based on a single-center registry of patients who underwent isolated CABG for multivessel CAD and LVD between January 2014 and December 2022. Primary outcome was in-hospital mortality. Secondary outcomes were early complications, graft patency rate at 3 months, readmission rate within 6 months, and freedom from angina rate within 6 months. Results. A total of 112 cases were included in this study; 52 patients for TAR and 60 patients for conventional CABG. Both groups had comparable baselines and operative profiles. In-hospital mortality was similar between TAR and conventional CABG (2 deaths, 3.85% vs 4 deaths, 6.67%,
