|Recommendation||Grade of Recommendation∗|
|At present, routine CT imaging following TAVI/TAVR is not recommended||Strong|
|CT should be considered in the setting of clinical concern for valve thrombosis, infective endocarditis, or structural valve degeneration||Strong|
|Leaflet thickening should be described based on location, extent in length and overall thickness||Strong|
|Restricted motion should be reported as present or absent||Strong|
|When available the size of the surgical valve in situ should be obtained from the patient records. When this is not possible, internal diameter may be measured and used for calculating the valve to be inserted||Strong|
|The relationship of the uppermost aspect of the surgical valve struts to the STJ and to the coronaries should be described||Strong|
|When the surgical valve struts end below the level of the coronary ostia, virtual transcatheter valve to coronary ostia distances do not need to be measured.||Strong|
|Stentless surgical valve in valve procedures should be interpreted and reported as for native TAVI/TAVR cases regarding risk of coronary occlusion||Strong|
CT = computed tomography; SOV = sinus of valsalva; STJ = sinotubular junction; TAVI = transcatheter aortic valve implantation; TAVR = transcatheter aortic valve replacement.
