Key result
Canine valve strips demonstrated a lower proportion of calcium after 9 weeks of subdermal implantation in rats compared to bovine pericardial and porcine valve strips.
Why the study?

Hypothesis-generating for canine valves in bioprostheses; leaves open translation to human durability.
Does the type of bioprosthetic tissue (bovine, porcine, or canine) affect the degree of calcification in a rat subdermal implantation model?
Canine cardiac valves may offer improved durability and reduced calcification for bioprostheses compared to bovine or porcine tissues.
Chung et al. (2001) studied Calcification of bioprostheses. Canine valve strips vs. Bovine pericardial and porcine valve strips was evaluated on Weight and calcium content. Canine valve strips demonstrated a lower proportion of calcium after 9 weeks of subdermal implantation in rats compared to bovine pericardial and porcine valve strips.
