Abstract
The conventional non-invasive and invasive technique have limitations in evaluating cardiac prosthetic valves and artificial valves. We have used continuous wave Doppler echocardiography to evaluate 48 patients with tissue and mechanical mitral valves implanted within 4 months prior to examination. The results are as follows. 1) Of these patients, male are 28. The mean ages of male are 35.60 (yr) and female are 41.82. 2) The differences of peak and mean velocities of prosthetic acardiac valves between male and female are not significant, but the differences of valvular size between male and female are significant(male:31.00±1.30(mm), female:29.36±2.11, p<0.01). 3) The difference of size and flow velocities between mechanical (Edwards-Duromedics) and tissue(Ionescue-Shiley) valves are not significant, but the ages of patients with mechanical valves are significantly lower than tissue valves(mechanical valve; 34.05±11.28, tissue valve; 43.62±11.26, p<0.01). 4) The differences of flow velocities between mechanical and tissue valves, sizes of which are 31mm, are significant statistically (peak velocity; 130.15±24.59 vs 110.00±19.41, mean velocity; 74.49±23.14 vs 51.38±12.71, p<0.01). 5) The sizes of valves are larger, the peak and mean velocities are lower, but it is not significant statistically. The results indicated that Doppler echocardiography is a useful method for evaluating function of prosthetic valves.
