| |
|
| |
| '''Congenital Mitral Stenosis:'''
| |
| This is a rare entity which includes the following:
| |
| *hypoplasia of mitral valve annulus which is considered part of the spectrum of [[hypoplastic left heart syndrome]],
| |
| *mitral valve commissural fusion,
| |
| *double orifice mitral valve,
| |
| *thickened [[chordae tendinae]], and
| |
| *[[Shone's syndrome]] which consists a set of four cardiac defects:
| |
| :::*parachute mitral valve,
| |
| :::*supra-valve mitral membrane (SVMM),
| |
| :::*sub-[[aortic stenosis]],
| |
| :::*[[coarctation of the aorta]],
| |
|
| |
|
| |
| '''Acquired Mitral Stenosis:'''
| |
| *[[Rheumatic heart disease]]: MS is synonymous with [[rheumatic fever]] which occurs as a complication of '''group A streptococcal''' infection in genetically susceptible individuals.
| |
|
| |
| *[[Prosthetic mitral valve]]
| |
| *Mitral valve obstruction from [[left atrial myxoma]]
| |
| *Mitral annular calcification
