Arrhythmogenic right ventricular cardiomyopathy--time for Nordic cooperation!

Area of Science:

• Cardiology
• Electrophysiology
• Medical Imaging

Background:

• Arrhythmogenic right ventricular cardiomyopathy (ARVC) presents diagnostic challenges.
• Patient care organization requires specialized expertise and data collection.

Discussion:

• Echocardiographic studies reveal progressive right ventricular structural and functional changes over time in ARVC patients.
• Body surface ECG analysis shows prolonged electrical systole and action potential dispersion in ARVC, with greater right-sided alterations.
• Autonomic maneuvers impact right-sided ECG parameters more significantly in ARVC, correlating with stress-induced arrhythmias.

Key Insights:

• Increasing right ventricular outflow tract diameter is a consistent long-term echocardiographic finding in ARVC.
• Distinctive ECG patterns in ARVC, particularly concerning QT-end and QT peak-end intervals, aid in differentiating from healthy controls.
• Sympathetic activation disproportionately affects right-sided cardiac electrophysiology in ARVC.

Outlook:

• A Nordic registry for ARVC is proposed to consolidate data and enhance research.
• Collaborative efforts through registries are crucial for improving diagnosis and patient care in rare conditions like ARVC.
• Future research should focus on longitudinal studies and advanced ECG techniques for early ARVC detection and management.
