Postmyocardial Infarction Ventricular Aneurysm: JACC Focus Seminar 5/5.

Area of Science:

• Cardiology
• Cardiac Surgery

Background:

• Ventricular aneurysm is a rare but serious complication following transmural acute myocardial infarction.
• It can also arise from other cardiac, congenital, or metabolic conditions.
• This condition involves expansion across all cardiac layers, often affecting large segments.

Purpose of the Study:

• To review the complications and management of ventricular aneurysms.
• To highlight the role of multimodality imaging in diagnosis and therapeutic decision-making.
• To discuss current evidence regarding surgical and medical interventions.

Main Methods:

• Review of existing literature on ventricular aneurysms.
• Analysis of adverse events associated with ventricular aneurysms.
• Evaluation of the STICH trial findings regarding surgical ventricular reconstruction.

Main Results:

• Adverse events include angina, heart failure, mitral regurgitation, thromboembolism, and ventricular arrhythmias.
• Multimodality imaging is crucial for comprehensive assessment.
• The STICH trial found no survival benefit for surgical ventricular reconstruction added to coronary artery bypass surgery.

Conclusions:

• Surgical intervention is considered the gold standard but may not always improve outcomes.
• Additional therapies like heart failure management, anticoagulation, and antiarrhythmic treatment are often necessary.
• Implantable cardiac defibrillators can mitigate the risk of fatal arrhythmias.
