Albes and colleagues have documented the first prospective randomized trial comparing the hemodynamic performance of mechanical aortic prostheses with enhanced internal diameter to a conventional mechanical prosthesis with standard internal diameter. There has been extensive interest over the past decade in optimizing the effective orifice area of prostheses to achieve low mean transvalvular gradients and effective orifice area indices (EOAI) to prevent or reduce the phenomena of patient-prosthesis mismatch (PPM) (EOAI <0.85 cm²m²) and . . .
