Incremental value of three-dimensional transesophageal echocardiography over the two-dimensional technique in the assessment of a partially detached MitraClip

Abstract

We describe an elderly male patient with two MitraClip devices, one fixed and the other detached, in whom live/real-time three-dimensional echocardiography (3DTEE) provided incremental value and additional information compared to two-dimensional transesophageal echocardiography (2DTEE). 3DTEE offered the ability to comprehensively assess the mitral valve (MV) utilizing full volume and multiplanar reconstruction (MPR) modes. 3DTEE proved useful in assessing the position of the properly attached and the partially detached MitraClip, including assessment of orifice size and degree of mitral regurgitation (MR). In addition, trapping of MV chordae by both clips was noted in the 3DTEE image dataset and confirmed at the time of surgery. Chordal trapping was not detected by 2DTEE. 3DTEE proved useful in more accurately estimating the severity of residual MR with the MitraClips in place since the regurgitant jet vena contracta (VC) could be viewed en face and VC area measured by planimetry in the correct imaging plane as compared to limited linear images from 2DTEE.
