[HSF] re: Porcine vs pericardial for Hal and others

[Ani Anyanwu]

Hal
 
This would be most unusual as there are no reports I can find of stenosis as a dominant cause of failure of porcine valves - many papers do not report stenosis at all as a mode of failure in their porcine explants. Most series report calcification and cusp tears as cause of failure in the vast majority and of course this is the reason why anti-calcification therapy is touted as the magic that will improve longevity of porcine valves.
 
Are you including valves that you took out because they were undersized (relative stenosis or so called patient-prosthesis mismatch) or are these valves which were truly stenotic with fused leaflets with restricted motion. Do you usually see calcification in these stenotic porcine valves?
