Aortic stenosis in elderly hip fractured patients

Abstract

Aortic stenosis (AS) and hip fractures are unrarely seen in elderly patients. The decision whether to operate these patients or not remains difficult. The present study examined the characteristics of such patients and the possible interrelations with management and outcome. This retrospective chart review study was conducted in a tertiary hospital during a 10-year period. We looked for demographic, clinical and echocardiographic characteristics of the patients, as well as their in-hospital course, compared with 100 hip fracture patients without AS. We identified 71 patients with AS hospitalized for acute hip fractures, 62 out of whom were included in the final analysis. Mean age of AS patients was 85.9+/-7.4. Mean and peak AV gradient were 35.8+/-16.3 and 59.0+/-26.7 mmHg, respectively. Mean valve area was 0.97+/-0.64. Fifty-six AS patients (91%) were operated. Rate of major in-hospital complications was 8% compared with 3.6% in non-AS patients. In-hospital mortality was 6.5% compared with 3.3% in non-AS patients (p=0.01), respectively. One-year mortality was 17.7% (11/62) among AS patients and 16.1% in non-AS patients. Death of AS patients was not interrelated with age, gender, pre-fracture function or echocardiographic data (mean and peak AV gradients, ejection fraction and valve area). We conclude that surgery of hip fractured elderly with AS was associated with increased rate of major complications and in-hospital mortality rates, compared with controls; however, 1-year mortality rate was similar in both groups. It remains to be determined whether a more careful medical and surgical management of such patients will result in less eventful hospital course.
