Atrial Fibrillation and Catheter Ablation
Abstract
This multimedia educational feature outlines key principles in the diagnosis and management of atrial fibrillation (AF), focusing on catheter ablation as a therapeutic option. Experts explain the classification of AF paroxysmal, persistent, and permanent—and its relationship to elevated stroke risk due to atrial thrombus formation. The overview covers ECG-based diagnosis, risk stratification using the CHA₂DS₂-VASc score, and indications for anticoagulation therapy. Treatment pathways include rate control, rhythm control using antiarrhythmic drugs, and increasing adoption of catheter ablation for symptom relief and restoration of sinus rhythm. Ablation is shown to be effective for paroxysmal AF and is increasingly considered in persistent cases, with potential benefits for heart failure patients. The presentation emphasizes a personalized approach to AF care based on symptom burden, risk profile, and treatment goals, supporting the integration of procedural and medical therapy to optimize outcomes.
