Methods of estimation of mitral valve regurgitation for the cardiac surgeon Apostolakis EE; Baikoussis NGJ Cardiothorac Surg 2009[Jul]; 4 (�): 34Mitral valve regurgitation is a relatively common and important heart valve lesion in clinical practice and adequate assessment is fundamental to decision on management, repair or replacement. Disease localised to the posterior mitral valve leaflet or focal involvement of the anterior mitral valve leaflet is most amenable to mitral valve repair, whereas patients with extensive involvement of the anterior leaflet or incomplete closure of the valve are more suitable for valve replacement. Echocardiography is the recognized investigation of choice for heart valve disease evaluation and assessment. However, the technique is depended on operator experience and on patient's hemodynamic profile, and may not always give optimal diagnostic views of mitral valve dysfunction. Cardiac catheterization is related to common complications of an interventional procedure and needs a hemodynamic laboratory. Cardiac magnetic resonance (MRI) seems to be a useful tool which gives details about mitral valve anatomy, precise point of valve damage, as well as the quantity of regurgitation. Finally, despite of its higher cost, cardiac MRI using cine images with optimized spatial and temporal resolution can also resolve mitral valve leaflet structural motion, and can reliably estimate the grade of regurgitation.|Cardiac Catheterization[MESH]|Echocardiography, Doppler[MESH]|Humans[MESH]|Magnetic Resonance Imaging[MESH]|Mitral Valve Insufficiency/*diagnosis/*surgery[MESH]|Mitral Valve/diagnostic imaging/*surgery[MESH]|Severity of Illness Index[MESH]|Thoracic Surgery/methods[MESH] |
