A variety of innovative techniques and devices are being developed for the percutaneous management of mitral insufficiency.
More than 30 devices are in stages of development from early stage to human pivotal trials. Two devices for the management
of degenerative myxomatous disease of the mitral valve replicate the Alfieri edge-to-edge surgical repair. One of those devices,
the Evalve Mitraclip, is in a pivotal trial at the current time. The other devices address functional mitral regurgitation
by a variety of techniques for performing mitral valve annuloplasty. The majority of devices take advantage of the proximity
of the coronary sinus to the posterior mitral annulus to deliver devices that remodel the mitral annulus. Two devices perform
septal lateral cinching decreasing the anterior posterior diameter of the mitral annulus and correcting leaflet malcoaptation.
Numerous issues are discussed including regulatory hurdles and the integration of percutaneous techniques into clinical practice
in a safe and efficacious manner.
