Mitral valve Wilkins echo score has have shown to be an important factor in determining immediate outcome of patients undergoing surgical mitral commissurotomy. Patient selection has an important impact on the outcome of percutaneous balloon mitral commissurotomy.
Nine hundred and ninety (990) patients with rheumatic mitral stenosis who underwent PTMC were evaluated . Out of 990 patients 60 patients had Wilkins Echo score more than 8(9-12) (Group-1) and rest 930 patients had low and medium Wilkins Echo score less than 8(Group-2)
After PTMC mean mitral valve area increased from 0.80+/-0.11 cm2 to 1.46+/-0.27 cm2 as measured by echocardiography in group-1 and from 0.85+/-0.32 cm2 to 1.81 +/- 0.33 cm2 in group-2 . Mitral valve gradient reduced to 11.63 +/- 4.15 mm Hg from 32.46 +/- 03.94 mm Hg after PTMC in group-1 and 10.45+/-3.76 mm Hg from 26.64+/-04.12 mm Hg after PTMC in group-2 . Mean left atrial pressure as recorded by catheter before PTMC was 33.99+/-08.37 mm Hg while after PTMC it was 21.81+/-06.28 mm Hg in group-1 and 28.81+/-07.32 mm Hg while after PTMC it was 17.76+/-05.11 mm Hg in group-2.
Though PTMC is an effective procedure for patients with high Wilkins score but result is inferior to patients with low and medium echo score .
