SUPERIOR SEPTAL APPROACH VS LEFT ATRIOTOMY IN REDO MITRAL VALVE REPLACEMENT - A COMPARATIVE STUDY

Abstract :

Mitral valve replacement needs a good exposure of the mitral valve apparatus to assess the valve mobility, thickening, calcification  and  nature of sub valvular apparatus . In Redo surgeries , there will be dense adhesions of the pericardium with the underlying right ventricle, left ventricle and right atrium.1 In such conditions, selection of the surgical approach plays a crucial role for good visualisation of the mitral valve apparatus. Larger<o:p></o:p> operation area can be achieved by superior septal approach in which the inter atrial septum and  left atrial ( LA) roof will be opened .Conventional left atrial approach is a more familiar approach for mitral valve procedures in which sinus node artery will be well preserved2. In our study, we compared these two approaches for redo mitral valve replacement and analysed various parameters. Two groups were divided with 25 patients in each group. One group of patients undergo superior septal approach and the other group of patients with conventional left<o:p></o:p> atriotomy incision in redo mitral valve replacement.Our study results conveyed that superior septal approach appeared to be good alternative to conventional left atriotomy incision in redo mitral valve replacement.<o:p></o:p>
