title: [Evaluation of postoperative mortality and quality of life of patients over 75 years of age after valve replacement for aortic stenosis. Report of 110 cases].
abstract: The authors carried out a retrospective study of short and long-term mortality after aortic valve replacement and assessed the quality of life by the IRIS scale in patients over 75 years of age operated for severe aortic stenosis at the University Hospital of Brest between June 1990 and March 1995. The hospital files of 110 consecutive patients (71 women, 39 men; average age 78 +/- 2 years, range 75-85 years) were studied. The pre- per- and postoperative data was studied. Each survivor was contacted by telephone during the year 2000 and a health and IRIS quality of life questionnaire was sent to them. Precise information about patients who had died was obtained from the family and/or medical practitioner. In the preoperative period, 30.9% of patients had left ventricular failure. The average aortic valve surface area was 0.53 +/- 0.12 cm2. Of the patients who underwent coronary angiography (60%), one third had significant coronary lesions. Coronary artery bypass surgery was associated with aortic valve replacement in 10% of cases. Biological prostheses were used in 108 patients. The operative mortality was 8.2%. One year, 5 year and 10 year survival rates were 89.9%, 75.5% and 33.3% respectively. Of the survivors, 16.7% were in institutional care and 83.3% lived at home. A total of 77.8% were readmitted to hospital, about half of them for cardiac problems. Cardiac treatment was prescribed for 97% of patients. The quality of life questionnaire was completed by 35 patients: the quality of life was better than average in nearly 83% of these patients. Aortic valve replacement for aortic stenosis in patients over 75 years of age improves life expectancy which is almost the same as that of the normal population of the same age, and improves the quality of life by restoring functional autonomy, enabling the majority of them to live in their own houses most of the time.
