The Mitral Apparatus
This review deals with the functional anatomy of the six components of the mitral apparatus, namely, the left atrial wall, annulus, leaflets, chordae tendineae, papillary muscles, and left ventricular wall. Each component is considered individually, in the context of the apparatus as a whole, in relation to the mode of closure of the normal mitral valve, and in the light of many acquired and co...

متن کاملthe impact of sub-valvular apparatus preservation on prosthetic valve dysfunction during mitral valve replacement
conclusions preservation of mitral annulus and papillary muscle continuity may enhance post- mvr cardiac performance with low mortality and morbidity rates. the risk of pvd was not significantly higher than conventional mvr in our series. results the improvement of functional status was seen in almost all survivors but was more obvious in the group i. in early follow-up, 56.4% of group i cases ...
متن کاملMitral valve apparatus: echocardiographic features predicting the outcome of percutaneous mitral balloon valvotomy
OBJECTIVES To evaluate the significance of involvement of subvalvular apparatus in the outcome of percutaneous mitral balloon valvotomy (PMBV) in patients with mitral stenosis (MS) and to determine the predictive value of chordal length compared with current echocardiographic scores. METHODS Patients with significant MS were selected according to the Massachusetts General Hospital score (MGHS...
متن کاملMotion of mitral apparatus in hypertrophic cardiomyopathy with obstruction.
Motion of the mitral apparatus in hypertrophic cardiomyopathy with obstruction was investigated by conventional single dimensional and multidimensional echocardiography. In systole, anterosuperior displacement of the posterior papillary muscle, failure of mitral valve closure, and anterior motion of both mitral leaflets were shown. The anterior leaflet was seen to impinge on the posterior papil...
