Measurement of mitral orifice area in patients with mitral valve disease by real-time, two-dimensional echocardiography.
A quantitative assessment of mitral valve orifice area can be achieved in patients with pure mitral stenosis by cardiac catheterization. In the presence of mitral regurgitation, however, accurate measurement often is impossible because total diastolic flow through the mitral valve frequently is unknow. Using a recently developed real-time, two-dimensional echocardiography system, we are able to...
متن کاملNon-invasive assessment of mitral valve area during percutaneous balloon mitral valvuloplasty: role of real-time 3D echocardiography.
BACKGROUND In the last decade, multiple studies depicted discrepancies between mitral valvular orifice area (MVA) measurements obtained with the pressure half-time (PHT) method and invasive methods during the immediate post-percutaneous mitral valvuloplasty (PMV) period. Our aim was to assess the accuracy of Real-Time 3D echo (RT3D) to measure the MVA in the immediate post-PMV period. The invas...
متن کاملReal‐Time 3‐Dimensional Echocardiographic Assessment of Effective Regurgitant Orifice Area in Dogs With Myxomatous Mitral Valve Disease
BACKGROUND Effective regurgitant orifice area (EROA), calculated from the vena contracta width (VCW) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation. However, this simplified assumption only holds when the EROA is circular, which might not be true in dogs with myxomatous mitral valve disease (MMVD). HYPOTHESIS Effective regu...
متن کاملReal-time 3D transoesophageal measurement of the mitral valve area in patients with mitral stenosis.
AIMS Planimetry measured by two-dimensional transthoracic echocardiography (TTE, MVA2D) is the reference method for the evaluation of the severity of mitral stenosis (MS) but requires experienced operators and good echocardiographic windows. Real-time three-dimensional transoesophageal echocardiography (3D-TEE, MVA3D) may overcome these limitations but its accuracy has never been evaluated. M...
متن کاملTwo-dimensional echocardiography in double orifice mitral valve.
In a patient with endocarditis and significant aortic insufficiency, two-dimensional echocardiography revealed an abnormal mitral valve configuration with division of the valve into two separate orifices. At autopsy, a double orifice mitral valve with two sets of valve leaflets was observed. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is a...
