Results of off-pump coronary artery bypass grafting with off-pump first strategy in octogenarian.

BACKGROUND AND AIM

Ischemic heart disease is the leading cause of death around the world. Coronary artery bypass grafting offers efficient surgical revascularization for ischemic disease. Both on- or off-pump coronary artery bypass methods provide promising results to octogenarians, once complete vascularization is achieved. However, off-pump bypass requires a certain level of experience to achieve sufficient results. We have applied an off-pump coronary artery bypass-first strategy to all generations since 2008. This study investigated early and long-term results of surgical revascularization for octogenarians by a team with an off-pump-first strategy.

METHODS

All cases of isolated coronary artery bypass grafting performed since 2008 were identified and divided into a young group (age < 80 years) and an old group (age ≥ 80 years). Peri-operative results were investigated retrospectively in both groups and long-term results for the old group were assessed.

RESULTS

Among the 707 patients, 97% underwent off-pump bypass, and 94 cases were classified to the old group. Distal anastomoses and ventilator time were identical between groups (young vs. old: 3.3 vs. 3.2; 3.7 h vs. 3.7 h). In-hospital death rates were 0.5% and 0% in the young and old groups, respectively. With a mean follow-up of 1318 days, actual 1-, 3-, and 5-year survival rates for octogenarians were 92.1%, 81.2%, and 68.3%, respectively. Nearly half of the patients reached their nineties, which was close to the life expectancy of the national general octogenarian.

CONCLUSIONS

An experienced team with an off-pump-first strategy could provide valid therapeutic options for octogenarians.
