Abstract 【Objective】To evaluate the importance of the HATCH score on predicting effects of atrial fibrillation radiofrequency catheter ablation (AFRCA)．【Methods】 A retrospective analysis was carried out for 118 cases who underwent AFRCA with CARTO guidance from Dec. 2010 to Dec. 2013. They were divided into a recurrence group and a nonrecurrence group based on one year followup of sinus rhythm preservation. The clinical data and HATCH scores of the two groups were analyzed. 【Results】 The ratio of patients with hypertension, diabetes and stroke were higher in the recurrence group, and hsCRP,LAD and HATCH scores were significantly higher in the recurrence group compared to those in the nonrecurrence group(P＜0.05 and P<0．01). Furthermore, Multivariate Logistic regression analysis presented that increased HATCH score and LAD were independent influence factors of atrial fibrillation (AF) recurrence. The AF recurrence curves show that the cumulative recurrence rate of patients with a HATCH score≥2 was significantly higher than that of the nonrecurrence patients with a HATCH score of 0 or 1(P<0．01)． 【Conclusion】 When the HATCH score of the AF patients≥2 ,the recurrence risk after AFRCA is significantly elevated. So, HATCH score may be an effective predictor of the success rate of AFRCA．
