Early recurrence is a predictor of late failure in surgical ablation of atrial fibrillation Maroto Castellanos, Luis Carlos Carnero, Manuel Silva Guisasola, Jacobo Alberto Cobiella, Javier Pérez Castellano, Nicasio Reguillo Lacruz, Fernando José Pérez Villacastín Domínguez, Julián Rodríguez, José E. 616.12 Atrial fibrillation surgery Failure Risk factors Medicina Cardiología 32 Ciencias Médicas 3205.01 Cardiología We sought to determine if early recurrence of atrial fibrillation (AF) after surgical ablation is a risk factor of late failure. Between February 2004 to May 2009, 106 patients underwent surgical ablation of concomitant permanent AF with radiofrequency. Operations primarily consisted of valve surgery in 85% of patients. Hospital mortality was 2.8% (n = 3). The median follow-up was 37 months (interquartile rank 12-77), and was complete in 99% of patients. Freedom from AF was 82%, 76% and 68% at one, two and three years, respectively. Patients with early recurrence of AF had less prevalence of sinus rhythm in late follow-up (P < 0.001). Multivariate Cox regression analysis showed that AF duration [hazard ratio (HR) 1.014, 95% CI 1.009-1.020, P < 0.001] and early recurrence of AF (HR 3.45, 95% CI 1.50-7.95, P = 0.004) were independent risk factors for failure. In conclusion, in our series, early recurrence of AF after surgical ablation is a strong predictor of late failure.
