An L wave in pulse wave Doppler and M mode echocardiography represents continued pulmonary vein mid diastolic flow through the left atrium in to LV across mitral valve after early rapid filling. Presence of an L ‘ wave in these patients associated with higher E/E’ is indicative of advance diastolic dysfunction with elevated filling pressures.
mitral L wave in patients with atrial ?brillation (AF). Methods and Results Ninety-nine consecutive non-valvular chronic persistent AF patients were enrolled. The mitral L wave was de?ned as a distinct mid-diastolic ?ow velocity following the E wave with a peak velocity >20cm/s.
An L -wave is recorded as mid-diastolic ?ow across the mitral valve by M-mode echocardio-graphyorpulsed-waveDoppler.1 Recently,atis-sue Doppler correlate ( L `) has also been de-scribed.2 The term “ L -wave” was coined, as it follows the “J-” and “K-”waves of pulmonary To access a continuing medical education exam for this ar-, La onda L mitral puede encontrarse en la mesodiástole del flujo mitral . Puede evidenciarse mediante el Doppler pulsado, el Doppler tisular o el modo M sobre la válvula. Representa la continuación del pasaje de sangre desde las venas pulmonares a la aurícula izquierda luego de la fase de llenado rápido. Su presencia se atribuye a la combinación de varios factores: presiones de llenado …
Background Although Doppler color flow mapping is widely used to assess the severity of mitral regurgitation (MR), a simple, accurate, and quantitative marker of MR by color flow mapping remains elusive. We hypothesized that vena contracta width by color flow mapping would accurately predict the severity of MR. Methods and Results We studied 80 patients with MR.

Transmitral Doppler shows an early diastolic A wave and and an atrial systolic A wave, normally separated by a short interval in diastasis where there is no pressure gradient across the mitral valve when the normal valve is widely open. Tachycardia shortens the period of diastasis and leads to E-A fusion.
E/E’ ratio is not useful in mitral stenosis, although some studies suggest that tissue Doppler of the mitral annulus may provide a potential diagnostic role for the assessment of the left ventricular diastolic function in patients with mitral stenosis 4. Assessment of left ventricular filling pressures in mitral …
