Ventricular Remodeling after Myocardial Infarction

1993
Acute transmural myocardial infarction initiates a series of changes in left ventricular (LV) volume, regional function and geometry. This process, known as post-infarction LV remodeling, may continue for months or years following the initial ischemic event.

Ventricular remodelling: consequences and therapy

European Heart Journal, 1993
The mammalian left ventricle can change its size and shape in response to a variety of stimuli including loss of tissue and external work. These changes in size and shape, defined as remodelling, are the sum total of a number of processes that involve the myocyte and the interstitial fibrous structures which provide the matrix in which the myocyte ...

Myocyte proliferation and ventricular remodeling

Journal of Cardiac Failure, 2002
Improvement in the methodological approach to the analysis of the myocardium has provided clear evidence of cardiac myocyte proliferation, questioning the general belief that the growth of the adult heart under physiological and pathological conditions can occur only by cellular hypertrophy.

Global structural ventricular remodeling: Summation

Journal of Cardiac Failure, 2002
That the heart enlarges in patients with heart disease has long been known, but the structural details of this enlargement and the mechanism and rationale of this enlargement have only become apparent in recent years. As noted by Marc Pfeffer in his historical perspective, concepts were confused until quite recently.

Ventricular remodeling following myocardial infarction

The American Journal of Cardiology, 1992
Ventricular remodeling denotes structural changes that occur in ventricular chamber size, wall thickness, and composition following myocardial damage. Following acute coronary occlusion, there are various factors to consider at different times that may contribute to subsequent ventricular dilation.

Left Ventricular Pseudoaneurysm after Left Ventricular Remodeling

Innovations: Technology and Techniques in Cardiothoracic and Vascular Surgery, 2014
Cases 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), 1991
An 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, 1997
The 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, 2006
Bradycardic 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, 2014
Aortic 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 ...
