Figure 1. Transthoracic Echocardiogram showing severe Mitral annular calcification (MAC) and Degenerative Mitral stenosis (DMS). Parasternal Long axis (A) showing calcification of the posterior mitral annulus (arrow) and color flow acceleration across the mitral valve; Parasternal short axis (B) showing an extensive calcification of posterior mitral annular ring (arrow); Apical 4 chamber view (C) shows the extension of calcium on to the mitral valve leaflets (arrowheads) causing restriction; Continuous wave doppler across Mitral valve (D) shows a peak and mean gradient of 24 and 12 mmHg consistent with severe degenerative Mitral stenosis)
Figure 2. DMSI (Dimensionless Mitral Stenosis Index) sample calculation.
LVOT VTI (27 cm) / MV VTI (78 cm) = DMSI (0.35). LVOT-left ventricular outflow tract; MV VTI-Mitral valve velocity time integral; DMSI- Dimensionless Mitral Stenosis Index
