HYDRODYNAMIC RESULTS

Comparative study of the hydrodynamic function of six sizes 19 mm bileaflet heart valves.
J. Fischer - Eur J Cardiothorac Surg. 1995;9(12):692-5 discussion 695-6.

This figure shows that the largest effective orifice area during forward flow was calculated for Sorin Bicarbon valves.

This figure "shows the mean (± one standard deviation) pressure difference across the valve as a function of root mean square forward flow for the four flow conditions. The pressure difference across all six valves increased as the flow increased [...]. The HP and Bicarbon valves had the lowest pressure differences and these were significantly lower than the other four devices"

POST OPERATIVE DATA

Authors Comment
"We analyzed the cases of 105 patients who received a Bicarbon prosthetic heart valve implantation at the mitral and/or aortic position. This long-term single center study with a Bicarbon prosthetic heart valve shows excellent clinical results associated with a low incidence of valve related mortality and morbidity."
