Diagnosis of aortic stenosis in the elderly: role of echocardiography.
Doppler echocardiography provides accurate hemodynamic information for the diagnosis, assessment and follow-up of patients with aortic stenosis, making diagnostic cardiac catheterization redundant in most cases. Considering the rapid growth of the aging population and the high incidence of aortic stenosis, as the most common valvular heart disease in the age group, the authors have described the utility of the Doppler technique with a brief discussion of the clinical evaluation of these patients. Close observation of patients with asymptomatic aortic stenosis has been emphasized. Decision-making about the appropriate timing for aortic valve replacement is of immense clinical significance, which may be facilitated and achieved by the periodic follow-up and the use of this noninvasive method. Following a comprehensive echo-Doppler evaluation, the patient would only need coronary arteriography prior to surgery. The utility of hemodynamic and anatomic information by echocardiography in this type of surgery is emphasized.
