Hypothesis-generating for 19-mm bileaflet valve selection; leaves clinical translation and outcomes open pending in vivo data.
How do the hemodynamic performances of the Sorin Bicarbon, St. Jude Standard, and St. Jude HP 19 mm bileaflet prosthetic heart valves compare in steady and pulsatile conditions?
In vitro hemodynamic testing demonstrates that the Sorin Bicarbon 19 mm valve exhibits improved hemodynamics in pulsatile flow compared to steady flow due to its specific leaflet geometry.
