Definition

Noun: A ventricular aneurysm is a localized, abnormal bulging or ballooning of a weakened section of the wall of the heart's left ventricle. This condition typically develops as a complication following a myocardial infarction (heart attack), where the damaged heart muscle tissue is replaced by non-contractile scar tissue that stretches under pressure.

Usage

The term is used in medical contexts to describe a specific cardiac pathology. * The echocardiogram confirmed the presence of a ventricular aneurysm. * Surgical intervention may be required to repair a large ventricular aneurysm. * A complication of the heart attack was the formation of a ventricular aneurysm.

Advanced Usage

• "Aneurysmal dilation": This is a more general clinical term for an abnormal widening, of which a ventricular aneurysm is a specific type.
• The condition is often discussed in terms of its risk of complications, such as mural thrombus formation (blood clots within the heart chamber) or cardiac arrhythmias.

Variants and Related Words

• Cardiac aneurysm: A broader term that can refer to an aneurysm in any chamber of the heart, though it most commonly implies a ventricular aneurysm.
• Left ventricular aneurysm (LVA): A more precise synonym specifying the affected chamber.
• Aneurysm (noun): The general term for an abnormal bulge in the wall of a blood vessel or the heart.

Synonyms

• Left ventricular aneurysm (LVA)
• Cardiac aneurysm (in context)

Antonyms

• Normal ventricular wall
• Intact myocardium

Notes

This is a specialized medical term. It is not used in idiomatic expressions or phrasal verbs. The condition is distinct from aneurysms in arteries (e.g., aortic aneurysm).

Noun

1. a localized dilation or protrusion on the wall of the left ventricle of the heart (occurring after a myocardial infarction)
