Figure 1 Echocardiographic images of the mitral valve. (A) Yellow arrow indicates flail P3 portion of the MV with chordae rupture. (B) Color doppler images of TEE shows a severe mitral regurgitation with a big PISA radius. (C) Biplane images of targeting lesion on TEE. (D, E) Pathologic lesion and its corresponding color jet targeted for TEER in 3D views. (F) The MV opening area measure by 3D was 6.1 cm2.3D = 3-dimensional; MV = mitral valve; PISA = proximal isovelocity surface area; TEE = transesophageal echocardiogram.
Figure 2 TEER for severe mitral regurgitation. (A) second XT MitraClip was deployed adjusted to the first clip. (B) the second XT MitraClip became unclipped and unlocked.TEER = transcatheter edge-to-edge repair.

Figure 4 Fluoroscopic and TEE image of TEER for severe mitral regurgitation. (A) Fluoroscopic image of embolized clip was stucked in orifice of guiding catheter. (B) TEE image of embolized clip was stucked and did not pass through inter-atrial septum.TEE = transesophageal echocardiography; TEER = transcatheter edge-to-edge repair.
