Key result
Crimping and deployment of balloon-expandable valved stents significantly increased the hydraulic conductance of pericardial leaflets from 45.2 to 667.9 ml/h/m2/mmHg (P<0.001).
Why the study?
Does crimping and deployment of balloon-expandable valved stents increase the hydraulic conductance of bovine pericardial leaflets?
Does crimping and deployment of balloon-expandable valved stents increase the hydraulic conductance of bovine pericardial leaflets?
Absolute Event Rate: 667.9% vs 45.2%
p-value: p=<0.001
Crimping and deployment of balloon-expandable valved stents dramatically increases the hydraulic conductance of pericardial leaflets, providing a quantifiable measure of structural leaflet injury.

May indicate crimping-related leaflet injury risk; leaves open effects on clinical valve durability.
Convelbo et al. (2013) studied Leaflet injury during deployment of valved stents (n=6). Crimping and deployment of balloon-expandable valved stents vs. Non-crimped valved stents was evaluated on Hydraulic conductance of valved stent leaflets (p=<0.001). Crimping and deployment of balloon-expandable valved stents significantly increased the hydraulic conductance of pericardial leaflets from 45.2 to 667.9 ml/h/m2/mmHg (P<0.001).
