Study Notes
- Mitral annulus is a D or elliptical shape and measures 8.5-10 cm in length.
- Mitral annulus has two important structures: the right and left fibrous trigones.
- Mitral annulus contracts during atrial systole, which helps with left atrial filling.
- Mitral valve consists of two leaflets with equal surface area and three scallops.
- Papillary muscles and chordae tendineae support the leaflets and prevent prolapse.
- Mitral stenosis can be caused by thickening and fusion of the commissures, leaflets, or chordae.
- Mitral stenosis is usually asymptomatic until the 3rd or 4th decade of life.
- Mitral valve area <2 cm2 can lead to LA/LV gradient and elevated LAP.
- Mitral stenosis is often associated with rheumatic fever or other conditions such as SLE or RA.
- Mimicking pathologies include LA myxoma, ball-valve thrombus, and obstructive TPVDA.
