Ventricular aneurysms, outpouchings of the ventricle often after myocardial infarction (MI), can lead to heart failure and arrhythmias. Early MI treatment may prevent their formation and associated complications.

Area of Science:

  • Cardiology
  • Cardiovascular Medicine
  • Medical Diagnostics

Background:

  • Ventricular aneurysms are thin-walled outpouchings of the ventricle, typically occurring after transmural myocardial infarction (MI).
  • Infarct expansion early after acute MI is a precursor, with aneurysm formation related to infarct size.
  • Hypertension and certain medications may promote aneurysm development.

Purpose of the Study:

  • To review the pathophysiology, clinical sequelae, diagnosis, and management of ventricular aneurysms.
  • To highlight the importance of early MI treatment in preventing aneurysm formation.
  • To outline diagnostic methods and therapeutic strategies for managing complications.

Main Methods:

  • Review of existing literature on ventricular aneurysms.

  • Discussion of diagnostic modalities including echocardiography, radionuclide ventriculography, and cardiac catheterization.
  • Overview of management strategies encompassing prevention, medical therapy, and surgical options.

    • Main Results:

    • Ventricular aneurysms can result in congestive heart failure (CHF), thromboembolism, angina, and ventricular tachyarrhythmias.
    • Late rupture is a risk, particularly with false aneurysms.
    • Diagnosis is supported by clinical findings, ECG, chest X-ray, and confirmed by imaging.

    Conclusions:

    • Early therapeutic interventions during MI can limit infarct size, reducing aneurysm formation.
    • Management of CHF, thromboembolism, arrhythmias, and angina requires tailored approaches.
    • Prompt diagnosis and comprehensive management are crucial for improving patient outcomes.
