Normal mitral valve area
Normal mitral valve area (MVA)
Normal mitral valve area (MVA)
[A] ≥ 2.0 cm2
[B] ≥ 3.0 cm2
[C] ≥ 4.0 cm2
[D] ≥ 6.0 cm2
Normal mitral valve area (MVA)
- Normal mitral valve area (MVA) ≥ 4.0 cm2
- Normal area of the mitral valve orifice is about 4–6 cm2
- Mitral valve area less than 2 cm2 – valve create pressure gradient across the mitral valve.
- Mitral valve area less than 1 cm2- there will be an increase in the left atrial pressure to overcome the valve gradient.
- Symptoms consistently develop at MVA ≤1.5 cm
