OBJECTIVE To find various commissural morphologic predictors of immediate outcome of percutaneous transvenous mitral commissurotomy by two and three dimensional echocardiography. METHODS Design: Cross sectional study Setting: Teratiry care hospital Participants: Symptomatic patients with severe rheumatic mitral stenosis aged more than 12 years without any contraindications for the procedure. Intervention: 2D and 3D echocardiographic evaluation of commissural morphology was done by measuring

RESULTS Sixty-five patients were screened. Ten were excluded because of (commissural calcification 5, > moderate mitral regurgitation 2, thrombus in left atrium 2 and emergency procedure in a pregnant lady 1). Fifty five patients (29 (53%) men and 26 (47%) women), mean age 30.58 ± 9.27 were studied. The procedure was successful in 47 (86%) patients. The following parameters predicted the success; lower commissural fusion score by 3D echo 1.5 (0.5 – 2.0) vs. 2.0 (0.5 -2.0); p ≤ 0.002, higher intercommissural distance by 2D echo 19.0 (12.5 – 21.5) vs. 16.5 (12.0 – 18.5); p ≤ 0.009, lesser commissural thickness score 3D echo 5.0 (0.4 – 10.2) vs. 8.8 (3.9 – 10.0); p ≤ 0.028 as well as by 2D echo 5.1 (1.7 - 9.8) vs 8.5 (4.3 - 9.7); p < 0.037. Commissural thickness score by 2D echo was the best predictor of outcome (r=0.509, P<0.0001). CONCLUSIONS Comissural morphology is an important independent predictor of immediate outcome of percutaneous transvenous mitral commissurotomy.
