Implantation Depth and Rotational Orientation Effect on Valve-in-Valve Hemodynamics and Sinus Flow.

CONCLUSIONS: (a) Supra-annular axial deployment is associated with lower PGs irrespective of commissural alignment; (b) sub-annular deployment is associated with more favorable sinus hemodynamics, and less LF. Further in-vivo studies are needed to substantiate these observations and facilitate optimal prosthesis positioning during ViV procedures. PMID: 29501642 [PubMed - as supplied by publisher]
