Graphical abstract
Figure 1
Figure 1
Two-dimensional TTE zoomed apical 4-chamber view, without (left) and with (right) color flow Doppler of the mitral inflow, demonstrates severe MAC (∗) and leaflet calcification (#) with associated proximal diastolic flow acceleration (A). Continuous-wave Doppler spectrum demonstrates an increased mean TMG of 10 mm Hg (B).
Figure 2
Figure 2
Two-dimensional TEE midesophageal apical 4-chamber view (0°), diastolic phase, demonstrates severe MAC (∗) with calcification of the mitral leaflets (#) and restricted leaflet opening (A). Continuous-wave Doppler spectrum across the mitral inflow demonstrates a normal TMG of 3 mm Hg (B). Spectral ghosting (mirroring artifact) is seen and should be avoided when tracing. The LVOT was measured in the apical 3-chamber, midsystolic view (120°) inner edge to inner edge at the hinge points (blue double arrow) while avoiding the calcification (∗) on the anterior mitral leaflet (C).
Figure 3
Figure 3
Three-dimensional TEE acquisition and multiplanar, diastolic reconstruction demonstrates the MV leaflets in 2 orthogonal planes (A, B), short-axis leaflet tip display (C), and volume-rendered reconstruction in the surgeon's view orientation from the perspective of the LA (D).
Figure 4
Figure 4
Two-dimensional TTE parasternal long-axis view (A) and apical 4-chamber (B) diastolic images demonstrate moderate posterior MAC (∗). The continuous-wave Doppler spectral display of the mitral inflow obtained from the apical 4-chamber view demonstrates an increased TMG of 9 mm Hg (C).
Figure 5
Figure 5
Three-dimensional TEE acquisition and multiplanar, diastolic reconstruction demonstrates the MV leaflets in 2 orthogonal planes (A, B) and short-axis leaflet tip display (C), which allows for direct planimetry (MVA = 4.4 cm2). A corresponding CCT-derived short-axis slice of the MV leaflet tips (D) during diastole demonstrates a similar MVA by planimetry (MVA = 4.4 cm2).
