Evaluation of bioprosthetic valve performance as a function of geometric orifice area and space efficiency— A reliable alternative to effective orifice area
Performance comparisons among commercially available bioprosthetic valves are needlessly complicated by unreliable and complex parameters and exaggerated information from manufacturers. In addition to the issues surrounding the comparisons among valves, surgeons who are selecting the best fit for the patient on the operating table are hampered not only by the faulty parameters mentioned above but by selection tables based on these faulty parameters and by the often unachievable boundary between a proper match and an improper mismatch of the valve to the patient.
