Doppler evaluation of prosthetic mitral valves.
For the evaluation of patients with prosthetic heart valves Doppler echocardiography is superior over other noninvasive techniques because it allows quantitative assessment of valve function. As a noninvasive method Doppler is safe, easily repeatable and provides haemodynamic data that closely correlate with parameters obtained by invasive procedures (Sagar et al., 1986: Simpson et al., 1986; Wilkins et al., 1986; Gibbs, 1987). The purpose of our study was to evaluate Doppler characteristics of mechanical and tissue mitral prostheses; Starr-Edwards, Björk-Shiley, Hall-Medtronic and Hancock in patients with clinically normal valve function.
