Abstract

BACKGROUND
Because of rarity of study on aortic stenosis in the elderly which has progressively increased the clinical significance, we have performed this study to assess the degree and the clinical significance of aortic stenosis in the elderly. METHOD: According to the clinical features and echocardiographic findings, we have analyzed the trans-aortic peak pressure gradient, trans-aortic mean pressure gradient, left ventricular outflow tract(LVOT)/trans-aortic peak velocity ratio and aortic valve area from 3889 consecutive the elderly above the age of 60 or older(mean age 68, male 1953, female 1936) using Doppler echocardiography prospectively. RESULT: We have observed 162 cases of aortic stenosis in the elderly and among this, 16 cases were bicuspid aortic stenosis. The criteriae of hemodynamically significant aortic stenosis in the elderly using Doppler echocardiography and their frequencies were 23.4% as trans-aortic peak pressure gradient 45mmHg or more, 22.2% as trans-aortic mean pressure gradient 25mmHg or more, 26.5% as LVOT/trans-aortic peak velocity ratio 0.32 or less and 26.5% as aortic valve area 1.0cm2 or less.
CONCLUSION
In the current study, we have found that trans-aortic peak pressure gradient, trans-aortic mean pressure gradient, LVOT/trans-aortic peak veolcity ratio and aortic valve area using Doppler echocardiography were useful and adjuvant in diagnosing and evaluating the aortic stenosis in the elderly.
