[The new ESC guidelines on the management of ventricular tachyarrhythmias : Implications for daily practice]

Area of Science:

• Cardiology
• Electrophysiology
• Public Health

Context:

• The European Society of Cardiology (ESC) has released updated guidelines for managing ventricular arrhythmias and preventing sudden cardiac death, superseding the 2015 version.
• These guidelines introduce novel recommendations, including a dedicated section on public basic life support and updated acute treatment strategies for ventricular arrhythmias and electrical storm.

Purpose:

• To provide clinicians with the latest evidence-based recommendations for the diagnosis, risk stratification, and management of ventricular arrhythmias and sudden cardiac death.
• To integrate advancements in diagnostic tools like genetic testing and cardiac magnetic resonance imaging, and refine long-term management strategies, including pharmacotherapy and catheter ablation.

Summary:

• The guidelines update electrical cardioversion protocols, introduce a focus on electrical storm management, and present new diagnostic evaluations structured by clinical scenarios.
• Genetic testing and cardiac magnetic resonance imaging are emphasized for both diagnosis and risk stratification. Long-term pharmacotherapy aligns with heart failure guidelines.
• Catheter ablation's role is expanded for various ventricular arrhythmias, while primary preventive implantable cardioverter defibrillator (ICD) recommendations for dilated cardiomyopathy are adjusted, incorporating risk factors and calculators beyond left ventricular ejection fraction (LVEF).

Impact:

• These comprehensive guidelines offer a user-oriented reference with practical algorithms, aiming to improve patient outcomes in ventricular arrhythmias and sudden cardiac death prevention.
• The updated recommendations facilitate more precise risk stratification and personalized treatment strategies, particularly concerning ICD implantation and catheter ablation.
• The inclusion of public basic life support underscores a broader public health approach to managing cardiac emergencies.
