[Early outcomes of isolated aortic valve replacement in octogenarians].

We retrospectively studied early outcomes of isolated aortic valve replacement (AVR)in octogenarians. From November 2006 to October 2012, 70 patients underwent AVR and we divided them into 2 groups:group O (24 patients aged 80 years or older, 80~91 years;mean age, 85.0 years);and group Y(46 patients aged younger than 80, 39~79 years;mean age, 69.0 years). There were no significant differences in preoperative comorbidities between the groups, but the logistic EuroSCORE( 13.5% in the group O, 5.3%in the group Y) and EuroSCORE II (4.5% in the group O, 1.7% in the group Y) were significantly higher in the group O. The amount of blood transfusion needed was greater in the group O, but there were no differences between the groups with regard to the operation time, cardiopulmonary bypass time or aortic cross-clamp time. Operative mortality (4.2% in the group O, 2.2%in the group Y)and postoperative complications were not significantly different between the groups. Early outcomes of AVR in octogenarians were good and the newly refined EuroSCORE II showed a good correlation within the studied population.
