Role of the Imager in Transcatheter Mitral Valve Repair.

PURPOSE OF REVIEW

To describe the key role of the structural imager/interventional echocardiographer in transcatheter mitral valve therapies, particularly edge-to-edge repair. In addition, we review important recent advances in structural imaging and briefly describe several novel devices for transcatheter mitral valve repair.

RECENT FINDINGS

Structural imagers represent a new subspecialty in cardiology and anesthesiology with specific skillset and training requirements. Their role is particularly important in imaging-based transcatheter interventions such as edge-to-edge mitral valve repair. This therapy has increasingly been used to treat primary (degenerative) mitral regurgitation when surgical risk is prohibitive and has recently been extended to patients with secondary (functional) mitral regurgitation. As novel transcatheter therapies continue to emerge, so do new multimodality imaging technologies. Structural imagers have become an integral part of the heart team. Their role is particularly visible in transcatheter mitral procedures. Rapidly developing transcatheter therapies have helped shape this new subspecialty and spark innovation in imaging technologies.
