Abstract

Left ventricle dysfunction and comorbidities are responsible for a large number of complications after CABG. OPCAB could be an interesting alternative for very high-risk patients. Patients were included if EuroSCORE >9, or with at least two of the following criteria, severe LV dysfunction, recent myocardial infarction (MI), terminal renal failure, lung dysfunction, PVD, BMI>30. Patients were operated using the Octopus (Medtronic) system. One hundred and twenty patients, mean age 68+/-10 years, 72% male, were operated. Mean EuroSCORE was 10.2+/-5.3, LV function 36.79+/-11.3%, recent MI 57%, renal failure 52%, COPD 44%, PVD 52%, obesity 34%. Mean graft per patient was 2.1+/-0.8. Three patients underwent secondary PTCA treatment for incomplete revascularization. Combined surgery was required for 20%. Early mortality was 3%. Intensive care unit stay was 2.7 days. Early complications were: low output syndrome 3%, MI 0.8%, stroke 0.8%, kidney support 7%. Graft patency was systematically analyzed with MCTA or angiocardiography. OPCAB strategy seems to be safe and secure in this population of very high-risk patients reducing multi-organ failure. However, long-term results are needed to confirm this strategy.
