Pre-procedural imaging of the aortic root is essential for selection of the correct valve prosthesis and to minimize complications as prosthesis mismatch, possibly subsequent embolization, coronary obstruction, annulus rupture or severe aortic regurgitation.\n\nThe aim of the study is to compare the different imaging modalities for aortic root measurements.\n\nAortic root imaging will be performed prior to TAVI-procedure. The contrast injection will be performed either into the aorta or into the left ventricle. The datasets will be assessed by blinded-independent observers in a multi-planar reconstruction view.\n\nThe study will be performed retrospectively (2009-2012) and prospectively starting 2013.",[78],"Aortic Valve Stenosis",[80,81,82,83,84,85],"transcatheter aortic valve implantation","CT","MRI","angiography","echocardiography","rotational C-arm CT","2020-10-28",{"date":88,"type":89},"2020-10-30","ACTUAL",{"date":91,"type":7},"2013-01",{"date":93,"type":73},"2030-12",{"name":60,"class":6},1]
