Ineffective Orifice Area: Practical Limitations of Accurate EOA Assessment for Low-Gradient Heart Valve Prostheses

ConclusionsThe volatility of the standard EOA formulation at low mean gradients combined with the difficulty in accurately measuring such small differentials with industry-standard fluid pressure transducers results in a performance metric which is very sensitive to test execution, particularly for low-gradient prostheses.
