Transkatheter Aortenklappenimplantation (TAVI)
Fig. 1 Example of angiography‐derived implantation depth (ID) measurement for balloon-expandable (A) and self-expanding (B) transcatheter heart valve (THV) as the range between the prosthesis below the aortic annulus plane (short arrows) at the noncoronary cusp to the native aortic annulus plane in the prosthesis in an orthogonal view. ID is expressed as length and percentage of frame height below the aortic annulus. Example of multislice computed tomography (MSCT)-derived coronal membranous septum (MS) length as the distance from the most superior thinnest part of the muscular interventricular septum to the annular plane in the coronal view under the systolic phase (at 40% of the RR interval) (C)
