[Postinfarction remodeling and left ventricular aneurysm]

Abstract

The degree of cardiac insufficiency, which to a large extent is determined by changes in the volume and geometric characteristics of the left ventricle (LV), is an important prognostic factor of survival of patients after myocardial infarction. The term "postinfarction LV remodeling" was introduced to describe processes that lead to its dysfunction. This process becomes most important when postinfarction LV aneurysm (LVA) is formed. Recent research into the role of LV structure and mechanics show the hemodynamic significance of postinfarction LVA, especially in cases of its substantial expansion onto the interventricular septum (IVS). That is why a clear concept of the hemodynamic significance of postinfarction LVA and the extent of IVS involvement in a case with a prominent disorder of stereometric characteristics is a key factor for both choice of the optimal tactics and prediction of the end result of treatment of this threatening complication of coronary heart disease.
