ABSTRACT
With the progressive aging of the Japanese population, cardiac surgeons are increasingly faced with elderly patients. We have studied 29 consecutive patients, 80 years of age or older, who underwent aortic valve replacement at our institution between January 2000 and December 2003. Mortality, morbidity and late follow-up results were compared to those in 36 patients aged from 64 to 75 years old undergoing the same procedure over the same time period. The older patient group had a significantly higher incidence of calcified aortic stenosis and emergency operations and a higher score of NYHA functional class. Hospital mortality was 2 of 29 (6.9%) in the older patient group and 2 of 36 (5.6%) in the control group (ns). Postoperative renal failure and respiratory failure which needed prolonged ventilator support occured significantly more often in the older patient group. However, there was no significant difference between the 2 groups in terms of hospital stay. Almost all octogenarians showed improved NYHA functional class to class I or II after the operations. The actuarial survival rate was 89% in the older patient group and 78% in the control group at 3 years. The late survival rate and cardiac event-free rate were not significantly different between these 2 groups. Following aortic valve replacement, octogenarians, despite more compromised pre-operative status had good relief of symptoms, a favorable quality of life and a similar late survival to the younger patient groups. These findings support the recommendation that valve replacement should be performed in octogenarians with symptomatic aortic valvular disease.
