Echocardiographical demonstration of a progressively expanding left ventricular aneurysm preceded by endomyocardial tearing

Abstract

A 70-year-old woman with acute myocardial infarction (AMI) had a narrow necked left ventricular (LV) aneurysm and pericardial effusion. Although there had been no obvious sign of pseudoaneurysm at the first operation on the 13th day after onset, LV volume increased so dramatically that dyspnea on mild exertion was induced only 2 months after the onset of AMI. She underwent Dor's operation for the expanded LV aneurysm. The histological findings of the resected tissue, which were fibrotic epicardial lesion with small myocyte islands, indicated a true aneurysm. The ultrasound manifestation of a narrow necked aneurysm with abrupt thinning of the myocardium at the hinge point may be a valuable predictor of free wall rupture in the early phase and severely progressive LV remodeling in the late phase. Such aneurysms need to be considered as high risk.

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
