Left ventricular posterior wall movement in 20 patients with mitral stenosis (MS) was measured using M‐mode echocardiogram in order to evaluate the improvement of myocardial function after open mitral commissurotomy (OMC) and compared between the cases with (10 patients) and without (10 patients) papilloplasty. The maximum left ventricular end‐diastolic posterior wall velocity (LVPEVd max ) was increased from 71 ± 12 to 90 ± 16 mm/s in OMC patients (p < 0.01) and from 59 ± 19 to 101 ± 28 mm/s in OMC + P patients (p < 0.001). The maximum left ventricular systolic posterior wall velocity (LVPWVs max ) showed an increase from 51 ± 9 to 62 ± 10 mm/s in OMC patients (p < 0.02) and from 48 ± 10 to 69 ± 8 mm/s in the OMC + P group (p < 0.001). The mean LVPWVs increased from 35 ± 8 to 48 ± 8 mm/s in the OMC + P group (p < 0.01). These parameters correlate fairly well with stroke volume index (SVI), ejection fraction (EF), and fractional shortening (FS) derived from internal LV dimensions. Thus, the posterior wall movement may prove to be useful as an index for evaluating the improvement of LV function after OMC.
