TAVR Imaging Checklist
Region of Interest	Recommended Approach and Key Measures	Additional Comments
Preprocedure
Aortic valve morphology	TTE: Trileaflet, bicuspid or unicuspid Valve calcification Leaflet motion Annular size and shape	TEE if can be safely performed, particularly useful for subaortic membranes Cardiac MRI if echocardiography nondiagnostic ? ECG-gated thoracic CTA if MRI contraindicated
