Aortic systolic ejection murmurs are common in elderly persons.1–3 Calcific deposits in the aortic valve are also common in elderly persons and may lead to valvular aortic stenosis (AS).2–4 We reported that aortic systolic ejection murmurs were heard in 220 of 473 elderly persons (47%) in a long-term health care facility in whom technically adequate M-mode and 2-dimensional (2-D) echocardiograms of the aortic valve were recorded.3 Two-dimensional echocardiographic evidence of valvular AS was present in 123 of 473 elderly persons (26%), and in 118 of 220 elderly persons (54%) with aortic systolic ejection murmurs.3 Continuous-wave (CW) Doppler recordings correlate well with direct pressure gradient measurements derived from cardiac catheterization in patients with AS.5–8 We performed a blinded prospective study to determine the prevalence of AS and its severity determined by technically adequate CW Doppler recordings correlated with physical signs of AS.
