Doppler echocardiography is the method of choice to evaluate prosthetic valve function, involving 2D imaging, leaflet mobility, transprosthetic gradients, and effective orifice area.
Doppler echocardiography is the preferred, non-invasive method for comprehensive evaluation of prosthetic valve function.
Affirms Doppler echocardiography for prosthetic valve surveillance; leaves open prospective comparisons with multimodality imaging.
Owing to its versatile, non-invasive, radiation-free, and low cost nature, Doppler echocardiography is undoubtedly the method of choice to evaluate prosthetic valve function. This evaluation follows the same principles used for the evaluation of native valves, with some important specifics and caveats described in this article. A complete echocardiography includes two dimensional imaging of the prosthetic valve, evaluation of valve leaflet/occluder morphology and mobility, measurement of the transprosthetic gradients and valve effective orifice area (EOA), estimation of the degree of regurgitation, evaluation of left ventricular size and systolic function, and calculation of systolic pulmonary arterial pressure.1

Pîbarot et al. (2011) conducted a review in Prosthetic valve function. Doppler echocardiography was evaluated. Doppler echocardiography is the method of choice to evaluate prosthetic valve function, involving 2D imaging, leaflet mobility, transprosthetic gradients, and effective orifice area.
