Abstract

To evaluate the utility of echo-Doppler (ED; PW, CW and color), 67 patients affected by pure mitral stenosis (20 M, 47 F, mean age 52 years) were submitted to ED examination. Right and left cardiac catheterization were performed in 20 patients within 24 hours before ED. Mitral area obtained by Doppler method (Hatle's formula) correlated highly with both echo-2 dimensional and hemodynamic area (r = 0.93, p less than 0.001; r = 0.95, p less than 0.001 respectively). It was possible to calculate systolic pulmonary pressure, in patients with tricuspid incompetence, (43.9 +/- 14.9 mmHg, range 25-80) which correlated significantly (r = 0.95, p less than 0.001) with hemodynamic data (40.2 +/- 12.7 mmHg, range 20-70). The left atrial-left ventricular pressure gradient was 15.6 +/- 6.9 mmHg, range 6-32; the mean pressure gradient was 8.4 +/- 3.7 mmHg, range 3-17; the pressure half time 170.2 +/- 62.3 ms, range 83-330. We observed different types of direction of transmitral jets: centrally directed (n = 34); forward antero-lateral wall (n = 28); toward interventricular septum (n = 5). The transmitral jets presented 4 different appearances: scimitar-shaped (n = 28); candle flame (n = 24); mushroom (n = 9); double-jets (n = 6). No correlation was observed between the different types of transmitral jets (direction and appearance) and the parameters obtained by Doppler (PW and CW): velocities, pressure half-time, gradients. Thus, Doppler echocardiography permits a complete anatomic and functional evaluation of patients with pure mitral stenosis. We have not observed any correlation between the hemodynamic data and the different types of transmitral jets visualized by color Doppler.
