Introduction:
Arrhythmogenic cardiomyopathy (ACM) is a rare but serious condition linked to specific genetic mutations, such as TMEM43 and phospholamban mutations. These mutations can significantly impact heart function, often leading to sudden cardiac death or heart failure. Understanding electrocardiographic (ECG) criteria is crucial for early detection and management.

Key Findings from the Study

  • Founder Mutations & Their Impact:
    • TMEM43 (p.S358L) mutation is highly aggressive, requiring primary prophylactic implantable cardioverter defibrillator (ICD) implantation in men and women over 30.
    • Phospholamban p.Arg14del mutation leads to biventricular cardiomyopathy and is associated with progressive heart failure.Electrocardiographic
    • Poor R-wave progression in right precordial leads.
    • T-wave inversions in lateral leads (common in TMEM43 mutations).
    • Low voltage ECG and right bundle branch block (common in phospholamban mutations).
    • Presence of epsilon waves in right precordial leads and lead aVR.

Broader Implications in Cardiovascular Medicine

The American Heart Association (AHA) emphasizes the importance of genetic screening and ECG analysis in high-risk families for early intervention in arrhythmogenic cardiomyopathy. Identifying these mutations can help in preventing sudden cardiac deaths and optimizing treatment for affected individuals.
