Abstract
Objectives: Myocardial infarction is one of the leading causes of death worldwide. Beyond the acute mechanical complications, it is clear the pathophysiological evolution that affects the left ventricle which in some cases generates a “new valvulopathy” of the mitral valve. We will focus on secondary, post ischemic mitral insufficiency with particular attention to surgical indications and the new repair techniques. Methods: In this chapter the triggering factors and physiopsathological mechanisms that characterize the onset of mitral valve insufficiency will be analyzed. In addition, the surgical indications for the best treatment of mitral valve insufficiency according to international guidelines will be presented. Results: Our work has shown the importance of understanding the pathophysiological mechanism in order to perform the repair of mitral valve disease in the best possible way, highlighting the most modern and recent techniques of mitral valve repair using subanular techniques. Conclusions: Having established the pathophysiological mechanism well and applying the most suitable mitral repair techniques, it is now possible to perform a correct and lasting repair of the mitral valve by means of subanular techniques as regards post ischemic mitral valve disease.
