In classical mitral stenosis (MS) a reduced early diastolic closing motion of the anterior mitral leaflet (AMD is associated with anterior motion of the posterior mitral leaflet (PML), parallel to AML, Reduced diastolic motion of AML is also caused by reduced left ventricular compliance or primary pulmonary hypertension. In these cases, however, the PML moves normally, posteriorly, away from the AML. Posterior motion of PLM has been used to exclude MS. We report 16 out of 167 cases of MS in whom the PML moved posteriorly in normal direction. In these cases, echocardiograohic diagnosis of MS was made by (a) thickening of the mitral leaflets and (b), reduction of absence of atrial wave of AML, when in sinus rhythm. The degree of MS or mitral insufficiency did not correlate with the direction of the PML motion. We suggest that the PML motion depends on the type of MS: Cuspul versus Commissural or Chordal. While in most cases the PML moves anteriorly, its posterior motion should not exclude MS. |
