Focus on arrhythmogenic right ventricular cardiomyopathy.

Area of Science:

• Cardiology
• Genetics
• Pathology

Background:

• Arrhythmogenic cardiomyopathy (ACM) is a myocardial disease characterized by fibro-fatty replacement of cardiomyocytes.
• Desmosomal mutations are a common cause, predominantly affecting the right ventricle, but biventricular and left-dominant forms are recognized.
• ACM primarily impacts young adults and athletes, presenting with ventricular arrhythmias, heart failure, and sudden cardiac death.

Purpose of the Study:

• To provide an overview of arrhythmogenic cardiomyopathy, including its evolving definition and clinical presentation.
• To highlight diagnostic criteria and current management strategies, focusing on sudden cardiac death prevention.
• To discuss risk factors and the emerging role of risk prediction tools.

Main Methods:

• Review of current literature on arrhythmogenic cardiomyopathy.
• Analysis of diagnostic criteria (Task Force Criteria, 2010).
• Discussion of therapeutic strategies, particularly implantable cardioverter-defibrillators.

Main Results:

• ACM is defined by progressive fibro-fatty tissue replacement of the myocardium.
• Diagnosis relies on a combination of clinical, instrumental, and genetic findings.
• Implantable cardioverter-defibrillators are the primary strategy for preventing sudden cardiac death.

Conclusions:

• Arrhythmogenic cardiomyopathy is a complex myocardial disease with significant implications for young individuals and athletes.
• Adherence to diagnostic criteria and timely intervention are crucial for patient management.
• Further validation of risk stratification tools is necessary for optimizing patient care.
