Overview
Aneurysm of the heart, particularly involving the left ventricular wall, represents a localized dilation of the myocardium often associated with myocardial infarction or genetic conditions. These aneurysms exhibit distinct morphological features including dystrophic changes, hypertrophy, and varying degrees of fibrosis and inflammation 1.Diagnosis
Clinical Presentation: Often asymptomatic but can present with heart failure symptoms, arrhythmias, or embolic events.
Imaging: Echocardiography is crucial for initial detection and assessment of aneurysm size and function 1.
Histopathology: Demonstrates specific features such as dystrophic calcification, myocyte hypertrophy, and fibrosis; inflammatory infiltration may be noted in some cases 1.
Metabolic Activity: Increased proteosynthesis and pentose-phosphate shunt activity observed in affected tissues, particularly in areas with significant inflammation 1.Management
Surgical Intervention: Indicated for symptomatic aneurysms or those causing hemodynamic compromise, typically involving resection and patch repair 1.
Medical Management: Includes anticoagulation to prevent thromboembolism, especially in mobile aneurysms 1.
Risk Factor Modification: Control of hypertension, lipid management, and lifestyle modifications to reduce cardiovascular risk 1.Special Populations
Elderly: Surgical risks increase with age; careful risk-benefit assessment is essential 1.
Comorbidities: Presence of comorbidities like diabetes or chronic kidney disease may influence management decisions, emphasizing the need for tailored approaches 1.Key Recommendations
Echocardiography for Diagnosis and Monitoring: Essential for diagnosing and assessing the progression of heart aneurysms 1. (Evidence: Moderate)
Surgical Repair for Symptomatic Aneurysms: Recommended for symptomatic patients or those with hemodynamic instability 1. (Evidence: Moderate)
Anticoagulation for Mobile Aneurysms: To prevent thromboembolic events, particularly in mobile left ventricular aneurysms 1. (Evidence: Moderate)References
