Clinical algorithm for assessment of non-central leakage of a bio-prosthetic valve. After assessment of the morphology of the implanted valve demonstrating leaflet motion and valve seating, the location of the leak, whether central or non-central, is assessed by CFD. If the leak is non-central, further detailed examination is needed to determine the location of the leak and whether it is non-paravalvular or paravalvular. If the leak is non-paravalvular, it is possible that the leak is the same as in this case and would require only protamine administration and observation.
