Artificial Heart Valve - Mechanical Valves - Fluid Mechanics
... Bileaflet valves typically have higher PI’s than tilted-disc models, which in turn have higher PI’s than caged-ball models ... dramatic in caged-ball valves than in tilting-disc and bileaflet valves ... Tilting-disc and bileaflet valves are comparable, with the bileaflet valves have a slightly larger regurgitation volume ...
Artificial Heart Valve - Mechanical Valves - Cavitation
... rare occurrence, in 1988 the Edwards-Duramedics bileaflet had 46 reported failures in 20,000 implants related to cavitation damage ... investigations have found that several tilting disc valves and only one bileaflet valve, the Edwards-Duromedics, generate cavitation within the ... Investigations have repeatedly demonstrated that bileaflet valves, with the exception of the Edwards Duramedics design, cavitate only at dP/dt levels well above the physiological range ...
