Table 1: Staging of Mitral Stenosis (MS)*
Stage | Definition | MV Anatomy | MV Hemodynamics | Hemodynamic Consequences | Symptoms |
A | At the risk of MS | -Mild MV doming during diastole | -Normal transmitral flow velocity | None | None |
B | Progressive MS | -MV area >1.5cm2 | -Diastolic pressure half-time <150ms | -Normal pulmonary pressure at rest | None |
C | Asymptomatic severe MS | -MV area ≤1.5cm2 | -Diastolic pressure half-time ≥150ms | Elevated PASP >50mm Hg | None |
D | Symptomatic severe MS | Same as C above | Same as C above | Same as C above | -Reduced exercise tolerance
-Exertional dyspnea |
MS – Mitral stenosis – Mitral value; PASP – pulmonary artery systolic pressure
