There is also a rare form of congenital mitral stenosis. In rheumatic mitral stenosis‚ the mitral valve orifice is slowly diminished by progressive fibrosis‚ calcification of the valve leaflets‚ and fusion of the cusps and subvalvular apparatus.

the backwater valve system and the overhead sewers. Backwater Valve System An option that you can use in implementing backflow prevention is to use backwater valve system on the sewer line. This kind of valve has a horizontal check valve that is designed in such a way that waste will flow in only one side. A metal disc is in such a manner that it will open as waste flows forward and then closes as it tries to come backwards. An option is to install a basin in front of the check valve at the waste
