Quantitation of mitral regurgitation using the systolic/diastolic pulmonary venous flow velocity ratio.
OBJECTIVES The purpose of this study was to test the hypothesis that pulmonary venous flow velocity ratios during systole and diastole in patients with mitral regurgitation (MR) correctly predict the quantitative degree of MR. BACKGROUND Pulmonary venous flow velocity measurements have thus far been used only for the qualitative assessment of MR. Recent studies have evaluated this method usin...
متن کاملEvaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملPeak mitral inflow velocity predicts mitral regurgitation severity.
OBJECTIVES Mitral regurgitation (MR) is a common echocardiographic finding; however, there is no simple accurate method for quantification. The aim of this study was to develop an easily measured screening variable for hemodynamically significant MR. BACKGROUND The added regurgitant volume in MR increases the left atrial to left ventricular gradient, which then increases the peak mitral inflo...
متن کاملColor M-mode regurgitant flow propagation velocity: a new echocardiographic method for grading of mitral regurgitation.
PURPOSE The aim of this study was to evaluate the reliability of mitral regurgitation color M-mode regurgitant flow propagation velocity (RFPV) in grading mitral regurgitation (MR). METHODS We prospectively examined 52 consecutive patients with grades of MR mild in 10 patients, moderate in 19 patients, and severe in 23 patients with quantitative pulse Doppler echocardiography. MR was evaluate...
متن کاملMitral regurgitation.
Accurate clinical assessment of the severity of mitral regurgitation is often difficult, and left ventricular cine-angiocardiography is probably the most commonly used method of estimating it. It is therefore important to try to determine the accuracy of this method and to identify as far as possible any causes of error. We have attempted to do this in a series of 137 patients submitted to oper...
