BACKGROUND One of the most important advantages of robotic beating heart connector totally endoscopic coronary artery bypass (C-TECAB) is early functional recovery, which would be beneficial for fragile patients, like octogenarians. However, the safety of C-TECAB in this challenging group of patients is still controversial. The aim of this study is to investigate the benefit of C-TECAB in octogenarians. METHODS We retrospectively reviewed patients undergoing C-TECAB from July 2013 to September 2017 in our center. We compared perioperative outcomes of patients 80 years or older versus younger. RESULTS During the study period, 308 patients underwent C-TECAB. Of these, 28 patients (9.1 %) were octogenarians. The majority of octogenarians were male (N = 22, 79 %), mean age of 83.8 ± 3.0 years. Octogenarians had higher rate of hypertension and atrial fibrillation compared to younger patients. C-TECAB was successfully performed with no conversion to sternotomy in octogenarians. The mean operative time (299 ± 83 minutes vs 281 ± 89 minutes, P = 0.309), rate of multi-vessel bypass (61% vs 58%, P = 0.798) and concomitant procedures (18 % vs 8 %, P = 0.084) were similar between octogenarians and younger patients. Postoperative complications including prolonged ventilation (> 24 hours), wound problems, acute kidney injury, myocardial infarction, and stroke were not observed in octogenarians. New atrial fibrillation was observed more frequently in octogenarians compared to younger patients (36 % vs 19 %, P =0.031). The mean length of hospital stay was similar between octogenarians and younger patients (3.9 ± 1.8 days vs 3.5 ± 3.0 days, P = 0.475). Twenty-two octogenarians (79%) were discharged directly to home. Perioperative mortality was 0 in octogenarians. Mortality at mid-term follow-up (mean 185 days) was 11 % (3/28) in octogenarians, and the reason of death was non-cardiac in all 3 patients. CONCLUSIONS In our experience, C-TECAB had favorable results in octogenarians with acceptable morbidity, mortality and excellent short length of stay similar to younger patients. Further studies will be necessary to evaluate longer-term outcomes of this approach in this group of patients.
