title: [Aortic valve replacement in 80- and over 80-year-old patients. Short-term and long-term results].
abstract: Due to demographic changes in average life expectancy, the age of patients undergoing cardiac surgery is increasing as well. We have reviewed the short- and long-term outcome in patients over 80 years of age after aortic valve replacement. From 01 Jan 1995 until 31 Dec 1998, 105 patients (76 women, 29 men between 80 and 89 years, median: 83) underwent aortic valve replacement. 42% presented with aortic stenosis, 58% with combined valve disease with leading stenosis. 53% (group A) received isolated valve replacement, 47% (group B) underwent myocardial revascularization as well. The in-hospital mortality rate was 8.9% for group A and 14.3% for group B. The follow-up time ranged between 10 and 243 weeks (median: 112 weeks). None of the patients had to be reoperated for prosthetic valve dysfunction or endocarditis. Bleeding complications due to anticoagulant therapy were not observed. Of the 11 deaths during the follow-up period, 5 (45%) were cardiac in nature and 2 (18%) related to stroke. Actuarial survival rates for group A were 98, 95 and 88% at 1, 2 and 3 years, and for group B 92, 84 and 84%, respectively. Permanent nursing care was not required 1 year after the operation by 98% of patients in group A (2 years: 95%, 3 years: 88%) and by 100% of patients in group B (2 years: 95%, 3 years: 88%). At an interval of 1 year after the operation 98% of patients in group A had not been hospitalized as a result of cardiac disorders (2 years: 98%, 3 years: 94%). The rates for group B were 90, 82 and 82%. Compared with younger age groups, aortic valve replacement in patients 80 years of age and older is associated with a distinctly increased mortality and morbidity. However, our data suggest that considering the poor prognosis of conservative therapy of symptomatic aortic valve disease, the functional status as well as life expectancy in this age group seems to be positively influenced by aortic valve replacement.
