OBJECTIVE: The number of older patients being referred for aortic valve replacement with or without combined coronary bypass grafting (CABG) is increasing. The aim of this study was to evaluate operative risk factors, early and long-term results of isolated aortic valve and aortic valve replacement combined with CABG in octogenarians and nonagenarians. METHODS: In the last 10 years, 285 very elderly patients who underwent aortic valve replacement either alone or in combination with coronary artery bypass grafts were retrospectively studied. The population was divided into two groups; isolated aortic valve replacement was performed in 188 patients (group A) and 97 patients had aortic valve replacement combined with coronary surgery (group B). RESULTS: The overall hospital mortality was 5.3%, without statistical difference between groups. The incidence of low-output syndrome was higher in group B (P = 0.0001). The multivariate analysis for hospital mortality showed that urgency status, ejection fraction (EF) <35%, intra-operative variables such as clamping time, need for intra aortic balloon pump and post-operative variables such as prolonged ventilation, dialysis, post-operative myocardial infarction and re-thoracotomy for bleeding were independent prognostic factors for hospital mortality. The mean follow-up time was 49.03 ± 19 months. Survival at one, three and five years was 97.1 ± 1.8%, 92.2 ± 2.2% and 82.4 ± 3.6% for group A and 97.2 ± 2.0%, 88.4 ± 2.7% and 75.6 ± 3.2% for group B (P = 0.62), respectively. Age, male gender, post-operative myocardial infarction, urgency status, dialysis, low EF, mean aortic gradient were risk factors for the impaired survival. CONCLUSIONS: In our experience, a careful pre-operative evaluation has yielded good surgical results even in older patients with different comorbidities. Associated coronary grafts slightly increase the surgical risk. The role of revascularization on long-term morbidity and mortality is still not clear. It is essential to compare the results of percutaneous and trans-apical aortic valve replacement with the literature results of conventional aortic valve replacement with and without CABG before it can be used as an alternative for very older patients.
