RESUMO

In this study of 46 patients with mitral valve prostheses, we report on the accuracy of the left ventricular maximum filling velocity (LVMFV) index as a diagnostic tool for valve dysfunction. Echocardiographic left ventricular internal dimensions were measured every 0.05 seconds, and every measure was transferred to an axis system. The tangent to this curve was traced at the point of maximum rate of increase of dimension, and the slope in mm/sec represents the LVMFV index.
