title: Influence of design and fixation pressure on fibrous sheathing in right-sided porcine aortic bioprostheses.
abstract: Valve dysfunction in right side implanted bioprostheses can be caused by fibrous sheathing and cusp retraction. A scoring system was employed to grade the macroscopic appearance of the cusp retraction. Stentless porcine aortic valves exhibit less cusp retraction when implanted in right-sided position than stented porcine aortic valves.
