Why the study?
The age of persons treated actively for valve disorders is increasing, necessitating more information about the prevalence of aortic valve disease in old age.
Population
501 randomly selected persons aged 75-86 years plus 76 persons aged 55-71 years
Design
Random population-based echocardiographic study

Informs expected aortic stenosis burden in aging populations; leaves open optimal screening and intervention strategies.
Calcific aortic valve stenosis is a significant health problem in the elderly, with a prevalence of 2.9% in those aged 75-86 years, yet many potentially operable patients do not undergo surgery.
Lindroos et al. (1993) studied this question.
