The indication for TAVI will be based on each local Heart Team decision. As per local institution\'s regulatory policy, each patient will provide a written informed consent for the TAVI procedure, anonymous data collection and analysis. Each center will use its own consent template.\n\nAll data will be collected in an electronic clinical report form (eCRF).\n\nSTUDY POPULATION Population\n\nAll consecutive patients diagnosed with type 0 or type 1 bicuspid aortic valve stenosis or steno-insufficiency disease, undergoing transcatheter aortic valve implantation, as per local standard of care.\n\nCASPER algorithm\n\nThe sizing of the THV will be performed according to the proposed algorithm.\n\nFirst step ("calcium impact"): subtract 1 mm in patients with aortic calcium volume ≥300 mm3 (i.e. ≥ Class I); no subtraction in patients with aortic calcium volume \\<300 mm3 (i.e. Class 0).\n\nSecond step ("raphe impact"): subtract 1 mm if the raphe length is ≥50% of the perimeter derived mean annulus diameter Further 0.5 mm will be subtracted if a high burden of calcium is distributed predominantly on the raphe site.\n\nIn case of bicuspid Type 0 the second step should be skipped.\n\nTranscatheter Aortic Valve Implantation Procedure\n\nTAVI will be performed according to the local standards of care. Balloon valvuloplastywill be performed to prepare for TAVI deployment, at operator\'s discretion. Balloon size should not exceed the minimal diameter of the aortic annulus at baseline.\n\nTAVI deployment will be performed as the current best practices. All Centers will be encouraged to implant THV according to the two cusp alignment technique. If necessary, post dilatation will be performed, based on the final hemodynamics and aortic regurgitation assessment. The postdilatation will be performed according to the calcium burden with a balloon size diameter equal to the minor annulus diameter or to the mean diameter.\n\nPost-procedural MSCT scan\n\nThe post-procedural MSCT scan must be performed between 2 and 30 days after the index procedure.\n\nPost implant measurements of THV dimensions (perimeter and area) will be obtained at inflow level, raphe level, and stent waist level (defined as the smallest dimension observed at any plane of the implanted prosthesis). If the raphe level corresponds to the stent waist level, only one measurement will be reported.\n\nEccentricity index will be calculated for each level. Eccentricity will be defined as 1-(minimal diameter/maximal diameter) and will be calculated both at the inflow and at the narrowest level.\n\nThe post-procedural raphe length (defined as the longest measurable dimension of the structure) will be measured at the same level of pre-procedural MSCT. The ratio between the pre and post-procedure raphe length will be calculated for the assessment of raphe shortening.\n\nStrut separation data will be acquired (maximal strut distance, mean strut distance, strut eccentricity index, i.e. maximal-minimal strut separation). The stent strut spaces will be measured separately at the inflow level, with the first stent strut defined as the strut closest to the commissure between the non-coronary and right coronary sinuses. The subsequent struts will be numbered clockwise in an ascending order (1-15 for the Evolut THV).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
