Abstract
Transcatheter mitral repair and replacement is a broad area in which many investigational devices exist. Due to the complexity of the mitral anatomy and the breadth of surgical options to treat the pathology, it is unlikely that a single transcatheter device can meet the clinical needs of this patient population. As such, transcatheter mitral devices are discussed in several groups including replacement devices, indirect annuloplasty devices, direct annuloplasty devices, edge-to-edge repair devices, chordal replacement devices, and left ventricular repair devices. Design criteria for an ideal device are discussed for each group, followed by a state-of-the-art description of the devices currently being developed.
