To compare a comprehensive cardiovascular magnetic resonance imaging (MRI) protocol with contrast-enhanced computed tomography angiography (CTA) for guidance in transcatheter aortic valve replacement (TAVR) evaluation.
Methods and results
Non-contrast three-dimensional (3D) ‘whole heart’ MRI imaging for aortic annulus sizing and measurements of coronary ostia heights, contrast-enhanced MRI angiography (MRA) for evaluation of transfemoral routes as well as aortoiliofemoral-CTA were performed in 16 patients referred for evaluation of TAVR. Aortic annulus measurements by MRI and CTA showed a very strong correlation (r=0.956,

p
<0.0001; effective annulus area for MRI 430±74 vs. 428±78 mm
2
for CTA,
p
=0.629). Regarding decision for valve size there was complete consistency between MRI and CTA. Moreover, vessel luminal diameters and angulations of aortoiliofemoral access as measured by MRA and CTA showed overall very strong correlations (r= 0.819 to 0.996, all
p
<0.001), the agreement of minimal vessel diameter between the two modalities revealed a bias of 0.02 mm (upper and lower limit of agreement: 1.02 mm and -0.98 mm).
Conclusions
In patients referred for TAVR, MRI measurements of aortic annulus and minimal aortoiliofemoral diameters showed good to excellent agreement. Decisions based on MRI measurements regrading prosthesis sizing and transfemoral access would not have modified TAVR-strategy as compared to a CTA-based choice.
Key Points
• ‘Whole heart’ MRI and CTA measurements of aortic annulus correlate very strongly.
• MRI- and CTA-based prostheses sizing are in excellent agreement.
• MRA and CTA equally guide TAVR access strategy.</description><identifier>ISSN: 0938-7994</identifier><identifier>EISSN: 1432-1084</identifier><identifier>DOI: 10.1007/s00330-018-5386-2</identifier><identifier>PMID: 29736853</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Aged ; Aged, 80 and over ; Angiography ; Angiography - methods ; Annuli ; Aortic valve ; Aortic Valve - diagnostic imaging ; Aortic Valve Stenosis - surgery ; Cardiac ; Cardiac Imaging Techniques - methods ; Cardiovascular system ; Computed tomography ; Correlation analysis ; Diagnostic Radiology ; Evaluation ; Female ; Heart ; Heart Valve Prosthesis ; Humans ; Imaging ; Imaging, Three-Dimensional - methods ; Internal Medicine ; Interventional Radiology ; Magnetic resonance imaging ; Magnetic Resonance Imaging - methods ; Male ; Medical imaging ; Medicine ; Medicine & Public Health ; Middle Aged ; Neuroradiology ; NMR ; Nuclear magnetic resonance ; Patients ; Pilot Projects ; Prostheses ; Prosthetics ; Radiology ; Sizing ; Surgery, Computer-Assisted - methods ; Tomography, X-Ray Computed - methods ; Transcatheter Aortic Valve Replacement - methods ; Ultrasound</subject><ispartof>European radiology, 2018-11, Vol.28 (11), p.4625-4634</ispartof><rights>European Society of Radiology 2018</rights><rights>European Radiology is a copyright of Springer, (2018).

To compare a comprehensive cardiovascular magnetic resonance imaging (MRI) protocol with contrast-enhanced computed tomography angiography (CTA) for guidance in transcatheter aortic valve replacement (TAVR) evaluation.
Methods and results
Non-contrast three-dimensional (3D) ‘whole heart’ MRI imaging for aortic annulus sizing and measurements of coronary ostia heights, contrast-enhanced MRI angiography (MRA) for evaluation of transfemoral routes as well as aortoiliofemoral-CTA were performed in 16 patients referred for evaluation of TAVR. Aortic annulus measurements by MRI and CTA showed a very strong correlation (r=0.956,
p
<0.0001; effective annulus area for MRI 430±74 vs. 428±78 mm
2
for CTA,
p
=0.629). Regarding decision for valve size there was complete consistency between MRI and CTA. Moreover, vessel luminal diameters and angulations of aortoiliofemoral access as measured by MRA and CTA showed overall very strong correlations (r= 0.819 to 0.996, all
p
<0.001), the agreement of minimal vessel diameter between the two modalities revealed a bias of 0.02 mm (upper and lower limit of agreement: 1.02 mm and -0.98 mm).
Conclusions
In patients referred for TAVR, MRI measurements of aortic annulus and minimal aortoiliofemoral diameters showed good to excellent agreement. Decisions based on MRI measurements regrading prosthesis sizing and transfemoral access would not have modified TAVR-strategy as compared to a CTA-based choice.
