Mitral valve leaflets

Mitral valve leaflets

The mitral valve is made up of two valve leaflets (the anteromedial leaflet and the posterolateral leaflet) and a ring around the valve, known as the mitral valve annulus. The orientation of the two leaflets resembles a bishop's miter, which is where the valve receives its name.

Percutaneous mitral commissurotomy (PTMC) has been approved as a standard treatment in patients with severe rheumatic mitral stenosis with suitable valve score.1,2 The procedure is technically successful in over 90% patients, and the long-term durability of commissurotomy is excellent in those with pliable mitral valve leaflets and minimally deformed submitral apparatus.The results are comparable to surgical commissurotomy in relieving the obstructed valve and maintaining a favourable outcome.2-7 Majority of cases undergo the procedure successfully using traditional transfemoral approach.
