Objectives: Robotic-enhanced minimally invasive direct coronary artery bypass grafting surgery (RE-MIDCAB) is based on the use of a robotic console and instrumentation for the dissection of the left internal thoracic artery (LITA). The LITA to left anterior descending (LAD) artery anastomosis is subsequently constructed through a mini thoracotomy. The purpose of this study is to present our experience of RE-MIDCAB outcomes in elderly patients.
Methods: From 2002 until 2015, 44 octogenarians (the mean age of 82.9 years) underwent RE-MIDCAB. The mean logistic EuroSCORE was 9.2. The majority of the patients were male with a medical history of hypertension, dyslipidaemia and previous coronary interventions. Of these patients 25% underwent RE-MIDCAB combined with percutaneous coronary intervention (PCI) for the treatment of multi-vessel disease (hybrid revascularization).
Results: All RE-MIDCABs and combined 'hybrid' PCI procedures were successfully completed. The mean intensive care unit (ICU) and hospital stay were 1.6 days and 10.9 days, respectively. There was 1 in-hospital mortality (2.3%). After an average follow-up period of 29.2 months, 5 patients required repeat revascularization procedures (9.1%). Mortality on follow-up was estimated at 25.6%.
Conclusions: Our report suggests that considering the age and frailty of the octogenarian population, RE-MIDCAB is a feasible and safe procedure which is associated with acceptable mid-term results.
