    Abstract:
    OBJECTIVES: In the last decade, cardiac surgery in octogenarians is becoming a routinely performed procedure in our Western countries. The functional benefit of this surgery had already been proved. The aim of this study was to evaluate operative mortality, to identify pre- and post-operative risk factors of early and late mortality, to assess the Euroscore count in this high-risk group of patient and to evaluate late results of this surgery. METHODS: We reviewed 215 consecutive patients with a mean age of 83+/-2 years having undergone valvular surgery. There were 127 female patients (57.1%) and 88 males (42.9%). One hundred and fifty-nine patients (74%) underwent aortic valve replacement 42 (19.5%) mitral surgery and 14 (6.5%) double valve surgery. There were 32 (14.9%) re-operative cases. Twenty-seven patients (12.6%) were operated on in emergency. There were 32 re-operations (14%). The EuroSCORE was used to assess predicted operative risk. Mean Euroscore additive count was 9.5+/-2.3 and mean logistic Euroscore was 15.1%. RESULTS: Operative mortality was 8.8% (19 patients). Left ventricular dysfunction was the only pre-operative significant risk factors of mortality (P=0.05). Low cardiac output (P<0.001), gastrointestinal complications (P=0.03) and surgical reexploration (P=0.001) were significant risk factors of mortality. Mean survival was 84% after one year and 56% after 5 years. CONCLUSIONS: Valvular surgery in octogenarians is a safe and low risk procedure compared to functional benefit and long-term survival. Our data how that logistic Euroscore overestimates the mortality in this high-risk group of patients.
