Piccini, MD, MHS; on behalf of the ORBIT-AF Investigators
Background-—The characteristics of patients undergoing atrial fibrillation (AF) ablation and subsequent outcomes in community practice are not well described. Methods and Results-—Using the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF), we investigated the prevalence and impact of catheter ablation of AF. Among 9935 patients enrolled, 5.3% had previous AF ablation. Patients with AF ablation were significantly younger, more frequently male, and had less anemia, chronic obstructive pulmonary disease, and previous myocardial infarction (P
