Non-Contrast Magnetic Resonance Angiography Assessment of Patients Referred for Transcatheter Aortic Valve Implantation

Can Non-Contrast Magnetic Resonance Angiography Accurately Define Arterial Access and Aortic Root Anatomy in Patients Referred for Transcatheter Aortic Valve Implantation?

The overall objective of this proposal is to examine the feasibility and accuracy of non-contrast magnetic resonance angiography (MRA) to comprehensively evaluate individuals referred for transcatheter aortic valve implantation (TAVI).

Inclusion Criteria:

• Adults with severe aortic stenosis referred for possible transcatheter aortic valve implantation with clinically indicated computed tomography imaging

Exclusion Criteria:

• Inability or unwillingness to consent
• Inability to complete magnetic resonance imaging (MRI) study
• Contraindication to MRI
• Participation in another research study
• Non-diagnostic computed tomography scan
