Small Björk-Shiley valves show in vitro promise for paediatric use; leaves open clinical translation and growth-related obstruction risk.
Do paediatric size Björk-Shiley tilting disc valves offer better hydrodynamic performance compared to Starr-Edwards ball valves in an in vitro model?
In an in vitro model, paediatric-sized Björk-Shiley tilting disc valves showed favorable hydraulic performance compared to larger ball valves, though the smallest sizes may still cause obstruction as stroke volume increases with growth.
Björk et al. (1972) studied this question.
