POST-MI REMODELING OF THE LEFT VENTRICLE REMODELING: A CARDIAC SURGEON’S STANDPOINT

ECG and echocardiography data of 152 coronary patients have shown posterolateral wall, as the most adaptable to hemodynamical stress and most compliant, to be the first involved in the process of post-MI dilation of the LV cavity in cases of ventricle aneurysm. Subsequently volume load on the posterior wall decreases thus alleviating regional subendocardial ischemia and improving contractility, assuring the participation of this LV area in global hemodynamics. In such cases LV posterior wall and particularly its basal areas contribute significantly to intotropic function maintaining sufficient stroke volume.
