title: Role of CMR in TAVR.
abstract: Multimodality imaging plays a critical role in planning, performing, and evaluating transcatheter aortic valve replacement (TAVR). Cardiovascular magnetic resonance (CMR) has been underutilized in this patient population to date, but there is increasing evidence that it can offer equivalent or even superior information to more commonly used imaging modalities, such as echocardiography or computed tomography for specific applications. In addition, CMR can provide incremental information, including advanced tissue characterization with late gadolinium enhancement and T1 mapping. In this paper, we review the evidence for CMR in TAVR and explore whether CMR should still be considered a research tool, or whether it is now ready for implementation into clinical practice.
