"WebIn general, evaluation of prosthetic valve function is more challenging, on the basis of the variability of inherent mild obstruction observed with the wide range of prosthetic valve types and sizes. Thus, the cardiac history plays a major role in the echocardiographic evaluation by documenting the type and size of the inserted valve or conduit. " - Hahn normal tavr gradients
