Left Ventricular Pseudoaneurysm after Left Ventricular Remodeling
Innovations: Technology and Techniques in Cardiothoracic and Vascular Surgery, 2014Cases of left ventricular pseudoaneurysm caused by patch leakage after left ventricular remodeling are quite rare. We describe the case of a 66-year-old man operated on through a left thoracotomy using the Port Access platform to treat patch detachment after left ventricular remodeling.

[Left ventricular remodelling].
Cardiologia (Rome, Italy), 1991An acute myocardial infarction, particularly one that is large and transmural, can produce expansion and alterations in the topography of both the infarcted and non-infarcted regions or the ventricle. This remodelling can importantly affect the function of the ventricle and the prognosis. Side-to-side slippage of myocytes in the myocardium occurring in

Myocyte cell death and ventricular remodeling
Current Opinion in Nephrology and Hypertension, 1997The recognition that cell death in the myocardium is not only necrotic in nature but is also mediated by activation of the suicide program of myocytes has raised several questions concerning the magnitude of this phenomenon, and whether these two distinct forms of cell death are disease-dependent or coexist in the pathologic heart.

Bradycardia‐Mediated Ventricular Electrical Remodeling
Journal of Cardiovascular Electrophysiology, 2006Bradycardic states are associated with myocardial electrical remodeling predisposing to potentially lethal ventricular tachydysrhythmias. We used a novel model of complete heart block (CHB) in the rabbit to test the hypothesis that ventricular activation rate is the primary determinant of early bradycardic electrical remodeling.

Left Ventricular Remodelling in Aortic Stenosis
Canadian Journal of Cardiology, 2014Aortic stenosis (AS) is a progressive condition associated with high mortality if not treated. The hemodynamic effects of AS have serious implications for the left ventricle. In this review, we describe the responses of the left ventricle to AS by highlighting the process of adaptive remodelling, which begins as a beneficial compensatory mechanism but ...

Surgical ventricular remodeling
Current Opinion in Cardiology, 2017The surgical management of patients with ischemic cardiomyopathy, especially those with left ventricular ejection fractions less than 20% has historically been controversial. The original trials of surgical revascularization versus medical therapy intentionally excluded those patients with an ejection fraction less than 35%. The significant advances in

Adrenergic pathways and left ventricular remodeling
Journal of Cardiac Failure, 2002Cardiac insufficiency, acute or chronic, engenders an increase in systemic and local myocardial sympathetic tone with release of the endogenous sympathetic hormones epinephrine and norepinephrine. These catecholamines activate cardiomyocyte alpha- and beta-adrenergic receptors which, although responsive to the same hormonal ligands, stimulate almost ...

Ventricular remodeling without cellular contractile dysfunction
Journal of Cardiac Failure, 2002A number of factors may contribute to progressive left ventricular (LV) remodeling and global LV dysfunction after myocardial damage. Important among these are loss of myocytes from necrosis or apoptosis, changes in the extracellular matrix (ECM), myocyte contractile dysfunction, and the purely geometric or mechanical effects of structural alterations ...
