BACKGROUND:Off-pump coronary artery bypass grafting (OPCAB) is a well-established alternative to conventional on-pump surgery, offering potential benefits in selected patients. This study presents a single-center, twelve-year experience with OPCAB, analyzing trends in surgical mortality and conversion rates to on-pump coronary artery bypass (ONCAB).
METHODS:Between January 2013 and March 2025, a total of 5,500 patients underwent OPCAB at our institution. Annual in-hospital mortality and the rate of intraoperative conversion to ONCAB were evaluated. Patient selection, surgical team experience, and perioperative protocols remained consistent but evolved with growing expertise over time.
RESULTS:Overall in-hospital mortality showed a significant downward trend from 4.5% in 2013 to 0.6% in 2024, reflecting improvements in patient selection, surgical technique, and perioperative care. Yearly mortality rates were: 2013 - 4.5%, 2014 - 4.8%, 2015 - 3.6%, 2016 - 3.4%, 2017 - 3.8%, 2018 - 4.2%, 2019 - 3.3%, 2020 - 2.8%, 2021 - 2.5%, 2022 - 1.5%, 2023 - 0.8%, and 2024 - 0.6%. The overall conversion rate from OPCAB to ONCAB was 4.5%. However, a consistent year-by-year decline was observed, culminating in only
2 conversions out of 500 cases in 2024 (0.6%), highlighting growing surgeon proficiency and better intraoperative planning.
CONCLUSIONS:Over a 12-year period, our experience with OPCAB demonstrates a significant reduction in operative mortality and conversion rates. The data suggest that with increasing experience and optimized protocols, OPCAB can be performed safely and effectively in a wide range of patients. Continued refinement of patient selection and technical skills contributes to improved outcomes and reduced need for intraoperative conversion to cardiopulmonary bypass.
