Benefit of Robotic Beating-Heart Totally Endoscopic Coronary Artery Bypass in Octogenarians

Abstract

Objective An important advantage of robotic beating-heart totally endoscopic coronary artery bypass (TECAB) is early functional recovery, in which fragile patients like octogenarians (age >80 years) benefit most. The aim of this study was to investigate the safety and feasibility of TECAB in octogenarians. Methods We retrospectively reviewed patients undergoing TECAB from July 2013 to September 2017 at our institution. Perioperative outcomes of octogenarian patients and that of younger patients were compared. Results Of 308 patients who underwent TECAB, 28 patients (9.1%) were octogenarians (mean age 83.8 ± 3.0 years). Octogenarians had a higher rate of hypertension and atrial fibrillation compared to younger patients. TECAB was successfully performed without conversion to any larger incisions in octogenarians. Mean operative time (299 ± 83 minutes vs 281 ± 89 minutes, P = 0.309) and the rate of multivessel bypass (60.7% vs 58.2%, P = 0.798) were similar between octogenarians and younger patients. New atrial fibrillation was observed more frequently in octogenarians compared to younger patients (35.7% vs 18.6%, P = 0.031). Mean length of hospital stay was similar between the 2 groups (octogenarians: 3.9 ± 1.8 days vs younger patients: 3.5 ± 3.0 days, P = 0.475). Twenty-two octogenarians (78.6%) were discharged directly to home. In-hospital mortality was zero in octogenarians. Conclusions Robotic beating-heart TECAB had favorable results in octogenarians with acceptable morbidity and mortality and excellent short length of stay similar to younger patients.
