[Interventional management of atrial fibrillation]

Area of Science:

• Cardiology
• Medical Technology
• Electrophysiology

Background:

• Atrial fibrillation (AF) prevalence is rising in the EU, projected to affect 14-17 million by 2030.
• Increasing AF cases necessitate advanced therapeutic interventions beyond traditional antiarrhythmic drugs.
• Current management strategies are evolving to address diverse patient needs and disease complexities.

Purpose of the Study:

• To review and highlight advanced therapeutic strategies for managing atrial fibrillation.
• To discuss the efficacy of ablation and left atrial occlusion in specific AF patient populations.
• To emphasize the role of personalized medicine and imaging in future AF treatment.

Main Methods:

• Review of current therapeutic interventions for atrial fibrillation.
• Analysis of outcomes for ablation (radiofrequency, cryoablation) and antiarrhythmic therapy.
• Evaluation of atrioventricular junction ablation with biventricular pacing for heart failure patients.
• Assessment of percutaneous left atrial occlusion for embolic risk reduction.

Main Results:

• Endocavitary or epicardial ablation offers superior symptom control and heart failure prevention compared to antiarrhythmic therapy for paroxysmal/persistent AF.
• Atrioventricular junction ablation with biventricular pacing is highly effective in advanced AF with heart failure.
• Percutaneous left atrial occlusion is a valuable alternative for preventing embolic events in patients with high bleeding risk and anticoagulant contraindication.

Conclusions:

• Advanced ablation techniques and left atrial occlusion represent significant progress in AF management.
• Personalized treatment strategies, guided by pre-procedural imaging, will be crucial for optimizing patient selection and outcomes.
• Future advancements will likely focus on new technologies and tailored approaches for individual AF patients.
