Abstract

In my present study (which included adult and foetal cadaveric study and clinical study) the morphology and morphometric analysis of mitral valve complex were studied and then compared and analysed with the works of many eminent scientists in this field. The present study to understand the anatomy of the constituent parts of the mitral valve complex not only helps examination of these parts in cross sectional interrogation but also enhances appreciation of valvar anomalies. The present study to analyse the detailed knowledge of the anatomy of slits and scallops of the mitral valve provides improved understanding of mitral valve function, which aids the surgeon in understanding valve pathophysiology and in designing reconstructive procedures. Detailed knowledge of normal papillary muscle formation is important to understand when and how various papillary muscle malformations develop and it is also of relevance in the early detection of these anomalies. In essence, the reparative procedure adopted for mitral incompetence should restore the chordal fan on either side. With this aim it is necessary to judge the type of repair required and to assess the length and number of chordal substitutes and location of site for reimplantation of ruptured chordae and papillary muscles. In mitral valve prolapse syndrome the left ventricle assumes various configurations which is possibly dependent on the architecture and location of papillary muscles, subject to pull by the prolapsing leaflet. In mitral valve replacement, retention of chordo papillary support is being favoured to preserve optimum function of left ventricle. However, if the native valve has too many chordae and papillary muscle bellies, these may interfere with the function of the disc or ball, especially if they were mostly intraluminal. Replacement of mitral valve with mitral homograft has been tried and is reemerging as a surgical alternative. Obviously, it is preferable to use homograft mitral valves with single anterolateral and posteromedial papillary muscle rather than multiple papillary muscles, which will be cumbersome to fix. The present study will be useful for cardiologists and cardiac surgeons in echocardiography, invasive cardiology and surgical reconstructive of mitral valves. The morphometric analysis is useful for cardiacsurgeons for determining the size of the prosthetic valve replacement, commissurotomy, commissuroplasty, valvuloplasty and artificial chordae tendineae replacement.
