[PATHOPHISIOLOGY OF POSTINFARCTION ANEURYSM OF LEFT VENTRICLE.]

Area of Science:

• Cardiology
• Cardiac Surgery
• Anesthesiology

Background:

• Postinfarction left ventricular aneurysm (LVA) is a serious complication following myocardial infarction.
• Transmural myocardial infarction leads to significant geometric alterations in the left ventricle.
• Anesthesiologists may encounter specific challenges related to LVA during surgical procedures.

Purpose of the Study:

• To define postinfarction left ventricular aneurysm.
• To describe geometric changes in the left ventricle post-transmural myocardial infarction.
• To outline adaptive mechanisms and potential arrhythmias associated with LVA, and review corrective procedures.

Main Methods:

• Review of existing literature on postinfarction left ventricular aneurysm.
• Analysis of geometric changes in the left ventricle.
• Discussion of anesthesiological considerations and arrhythmia sources.
• Overview of surgical correction techniques, with and without myocardial revascularization.

Main Results:

• Detailed definition and geometric characteristics of postinfarction LVA are provided.
• Adaptive physiological responses to LVA are described.
• Potential sources of life-threatening arrhythmias are identified.
• Evolution of surgical correction procedures, including revascularization, is presented.

Conclusions:

• Postinfarction LVA involves specific geometric remodeling and adaptive responses.
• Understanding potential arrhythmias and anesthesiological implications is crucial.
• Surgical correction, with or without revascularization, offers treatment options for LVA.
