Which of the following is a primary goal of catheter ablation in the treatment of atrial fibrillation?

Rationale: A. Catheter ablation does not directly improve myocardial contractility; its purpose is focused on electrical conduction rather than muscle strength. B. While controlling ventricular response may occur with medications, ablation targets the atrial electrical pathways rather than directly controlling ventricular rate. C. Anticoagulation decisions depend on stroke risk (e.g., CHA₂DS₂-VASc score); ablation does not automatically remove the need for anticoagulants. D. The primary goal of catheter ablation in atrial fibrillation is to eliminate abnormal electrical pathways causing arrhythmia, thereby restoring and maintaining normal sinus rhythm and reducing symptoms.
