Prosthetic patient mismatch aortic valve
WebbProsthesis-patient mismatch (PPM) occurs when the effective orifice area (EOA) of the prosthetic valve is too small in relation to a patient's body size, thus resulting in high … WebbPatient-Prosthesis Mismatch After Aortic Valve Replacement 97 Fig. 2. Curvilinear relation of the gradient and indexed EOA at stress. Based in this chart, PPM is considered present if indexed EOA (iEOA) is < 0,85 cm2/m2. It is graded moderate if the iEOA stands between 0,65 and 0,85 cm2/m2 and severe if less than
