Figure 4: Three-di- mensional transe- sophageal echocardi- ography color Doppler data for mitral regur- gitation quantifica- tion. The multiplanar reformation planes are aligned to obtain the three-dimension- al vena contracta (1.0 cm) and EROA (0.90 cm2). Panel a displays the three-dimension- al rendering of the mi-
tral valve. Panel b displays the reconstructed bicommissural mitral view, whereas panel c shows the reconstructed long-axis view. Panel d displays the transversal plane of the mitral valve at the level of the coaptation line where the anatomical vena contracta can be planimetered. EROA, effective regurgitant orifice area; mitral regurgitation, mitral regurgitation.
Figure 5: Fusion image of echocardiography and fluo- roscopy, facilitating the pro- cedural guidance during the MitraClip procedure. Panel a demonstrates real-time transesophageal image during the procedure where- as panel b shows the spatial orientation of that two-di- mensional view based on the fluoroscopic projection. The probe is detected indicating that the position of the probe relative to the C-arm has been detected leading to the overlaid of the transesopha- geal echocardiographic view
