Key result
Evaluation of 12 explanted bioprosthetic heart valves revealed early structural degeneration with collagen disruption, apoptosis, and serum osteopontin and TGF-β2 below the cohort mean in 70%.
Why the study?
Structural valve degeneration limits the durability of bioprosthetic heart valves, especially in younger recipients at index implantation.
Population
Twelve explanted BHVs from symptomatic patients undergoing redo valve replacement
Design
Prospective study

Should not yet change bioprosthetic valve selection or surveillance; hypothesis-generating for matrix-targeted strategies to enhance durability.
Observational (n=12)
Early structural degeneration of bioprosthetic heart valves is associated with collagen matrix disruption, cellular apoptosis, and pannus formation, highlighting potential targets for improving valve durability.
Gupta et al. (2026) conducted an observational in Structural valve degeneration (n=12). Bioprosthetic heart valves was evaluated on Histopathological, ultrastructural, and biochemical features of early SVD. Evaluation of 12 explanted bioprosthetic heart valves revealed early structural degeneration with collagen disruption, apoptosis, and serum osteopontin and TGF-β2 below the cohort mean in 70%.
