Forty octogenarians (OCTO) undergoing a variety of cardiac and thoracic aortic surgeries using cardiopulmonary bypass (CPB) between 1994 and 2002 were retrospectively studied. The results were compared with those of high-risk younger patients aged less than 60 years (YOUNG) (n=89). All patients had an expected operative mortality of EuroSCORE 5 and over. The EuroSCORE score was 9.9±3.3 (range, 5-18) in the OCTO group and 6.8+2.3 (range, 5-16) in the YOUNG patients (p<0.0001). There were 4 (10%) and 10 (11%) hospital deaths, respectively (p>0.99). Major postoperative complications occurred in 50% of the OCTO and 36% of the YOUNG patients (p=0.17). There were 10 and 7 late deaths, respectively. Actuarial survival including hospital death was significantly lower in the OCTO group than in the YOUNG (p=0.033). Actuarial survival was significantly higher in female octogenarians than in male (p=0.046). The overall 3-year survival rate was 88±8% and 64±11%, respectively. Multivariate analysis showed that predictors of late death were male gender (p=0.0005) and a high EuroSCORE (p=0.0010). Cardiac and thoracic aortic surgery using CPB can be performed in octogenarians with an acceptable hospital mortality rate and gratifying medium-term survival results. (Circ J 2003; 67: 539-544)
