Key result
Larger surgical valve size, supra-annular transcatheter heart valve type, and higher implantation depth reduce the incidence of elevated post-procedural gradients in aortic valve-in-valve procedures.
Why the study?
Does optimizing technical factors (THV type, implantation depth) improve hemodynamics in patients undergoing transcatheter aortic valve-in-valve procedures for failed bioprostheses?

May increase residual stenosis risk after valve-in-valve TAVR; leaves optimal valve selection and positioning open.
Does optimizing technical factors (THV type, implantation depth) improve hemodynamics in patients undergoing transcatheter aortic valve-in-valve procedures for failed bioprostheses?
Technical considerations such as supra-annular valve type and higher implantation depth are crucial for optimizing hemodynamics and reducing residual stenosis in aortic valve-in-valve procedures.
Yao et al. (2017) conducted a review in Failed surgical bioprostheses requiring aortic valve-in-valve procedures. Aortic valve-in-valve procedures was evaluated. Larger surgical valve size, supra-annular transcatheter heart valve type, and higher implantation depth reduce the incidence of elevated post-procedural gradients in aortic valve-in-valve procedures.
