RODRIGUEZ, Álvaro H  e  RIVERA, Diana P. Mitral valve repair in ischemic functional mitral insufficiency and echocardiography: Case series. Rev. Colom. Cardiol. [online]. 2011, vol.18, n.1, pp.55-58. ISSN 0120-5633.

Ischemic mitral valve insufficiency is a complication of coronary disease associated to poor results. Its basic mechanism is remodeling of ischemic left ventricle that causes the displacement of papillary muscles, annular dilation and valves apical traction. Although there is enough evidence that mitral valve repair is superior to mitral valve replacement for correction of severe organic mitral insufficiency, there is still a great dilemma as to which procedure is more suitable for its treatment. Apparently, now the most used technique for the surgical treatment of patients with severe ischemic mitral insufficiency is restrictive annuloplasty of the mitral valve; however, this procedure is associated to 10% to 20% of early post-operative persistence, and to 50% to 70% of recurrence rate at five years. Furthermore, the presence of persistent or recurrent severe ischemic mitral insufficiency is associated with increased incidence of cardiac events and reduced survival.
