[Quantification of mitral insufficiency in color Doppler by studying the convergence zone].
Many in vitro and in vivo studies have recently emphasized the value of analysis of the colour Doppler convergence zone for quantification of mitra insufficiency. This approach provides an estimation of the maximal instantaneous regurgitation flow rate, the area of the regurgitating orifice, the volume regurgitated with each beat and the regurgitation fraction. After a brief review of fluid mechanics, this review of the literature with be focus on the principle, results, advantages and limitations of this method.
