Why the study?
Does a collagen-sealed knitted Dacron conduit improve freedom from conduit replacement compared to tightly woven low-porosity Dacron conduits in patients requiring extracardiac conduits?

Collagen-sealed knitted Dacron conduits showed unsatisfactory clinical results with high rates of early reoperation for stenosis, indicating alternative sealing methods are needed.
No takes yet. Share an insight, caveat, or question.
Similar 3-year durability for valved and nonvalved conduits warrants caution with current Dacron options; leaves open need for improved materials.
Jonas et al. (1987) studied this question.
