What Is the Role of Cardiac Magnetic Resonance Imaging in Transcatheter Management of Aortic Valve Stenosis?

Transcatheter aortic valve replacement (TAVR) has changed the management paradigm of severe aortic stenosis. Cardiac magnetic resonance (CMR) has an emerging role in the evaluation of aortic stenosis. MRI provides excellent tissue characterization, endocardial definition, and is considered the gold standard for the assessment of left and right ventricular volumes, remodeling, mass, and chamber function. In addition, CMR is free from ionizing radiation, noninvasive, and an iodine-contrast sparing modality. CMR has a role in the assessment of annular dimensions, especially in individuals in whom computed tomography is contraindicated. This review discusses the contemporary role of CMR in patients with aortic stenosis, particularly in those being considered for TAVR.
