Key result
Bovine jugular veins for RVOT reconstruction are linked to ~10% more intact conduits versus cryopreserved homografts.
Why the study?
Does the use of bovine jugular veins improve long-term durability compared to homografts for RVOT reconstruction?

Comparison
Bovine jugular veins (n=444) vs Cryopreserved homografts (n=267)

Conduit durability comparisons via dual-center pooling warrant cautious interpretation; leaves open optimal selection pending randomized confirmation.

Does the use of bovine jugular veins improve long-term durability compared to homografts for RVOT reconstruction?
Bovine jugular veins appear to offer superior durability compared to cryopreserved homografts for RVOT reconstruction in patients younger than 25 years.
Blanz et al. (2015) conducted a cohort in Reconstruction of the right ventricular outflow tract (RVOT) (n=711). Bovine jugular veins vs. Homografts was evaluated on Fraction of patients whose conduits were not explanted, postinterventional, stenotic, insufficient, or stenotic and insufficient. In patients younger than 25 years, bovine jugular veins for RVOT reconstruction yielded at least a 10% higher fraction of intact conduits over 12 years compared with cryopreserved homografts.
