Transcatheter Interventions for Mitral Regurgitation: Multimodality Imaging for Patient Selection and Procedural Guidance

JJ Bax, P Debonnaire, P Lancellotti et al. Keywords: cardiac magnetic resonance; computed tomography; mitral regurgitation; transesophageal echocardiography

ABSTRACT

Transcatheter therapies to treat mitral regurgitation are rapidly developing. Currently, there are several devices commercially available to treat mitral regurgitation. The underlying cause of mitral regurgitation and specific anatomical aspects of the mitral valve and surrounding structures are considered when patients with symptomatic severe mitral regurgitation for transcatheter mitral valve therapies are selected. Multimodality imaging plays an important central role in the selection of patients, providing information about the mechanism of mitral regurgitation, the anatomy of the mitral valve and spatial relationships with the coronary sinus, the circumflex coronary artery and left ventricular outflow tract and to predict the procedural outcomes. During the transcatheter procedure, transesophageal echocardiography and fluoroscopy are key for monitoring the procedural steps to maximize the outcomes and minimize the complications. This paper provides a comprehensive review of the most important aspects to visualize in order to appropriately select patients for transcatheter mitral valve repair and replacement and to guide the procedure for the different transcatheter devices.
