| ====Hemodynamic and Clinical Outcomes====
| |
| * Results of the commissurotomy should be assessed with hemodynamics and echocardiography
| |
| * If second inflation is needed mitral regurgitation should be assessed
| |
| * In general increasing valve area to greater than 1 cm2/m2 is an acceptable result
| |
| * Usually the valve area doubles and the pulmonary pressures degrease immediately
| |
| * 5 year survival is in the 90% range

| == Factors favouring successful percutaneous mitral valvuloplasty ==
| |
|
| |
| Mitral stenosis is amenable to percutaneous mitral valvuloplasty if the echocardiography demonstrates :
| |
|
| |
| * Thickening confined to valve tips
| |
| * Good mobility of Anterior mitral valve leaflet
| |
| * Little chordal involvement
| |
| * not more than trivial [[mitral regurgitation]]
| |
| * no left atrial thrombus
| |
| * no commissural calcification.

| === Wilkins score ===
| |
|
| |
| A scoring system exists to grade the morphological changes in the mitral valve during assessment with echocardiography. This takes into account 4 characteristics: leaflet mobility, leaflet thickening, valve calcification and involvement of the subvalvular apparatus. The involvement is graded from 0-4. A total score of more than 8 is predictive of a low success post percutaneous mitral valvuloplasty.<ref>Wilkins GT, Weyman AE, Abascal VM, Block PC, Palacios IF.
