摘要：

To investigate the role of the geometry of the left atrial lateral ridge (LLR) in the atrial fibrillation (AF) recurrence after radiofrequency ablation (RFA). A total of 225 patients with AF who underwent RFA for the first time were retrospectively enrolled and divided into the recurrence (n = 53) and non-recurrence (n = 172) groups. The clinical data and the volume of left atrium (LAV) and the LLR geometry were analyzed. The LAV in the recurrence group was greater than that in the non-recurrence group (P < 0.001). There were more rectangular LLR in the recurrence group than the non-recurrence group (43% vs. 77%, P < 0.001). The anteroposterior diameter of the LLR orifice in the recurrence group was smaller than that in the non-recurrence group (P = 0.001), while the length of the LLR in the recurrence group was longer (P = 0.012). Multivariate analysis revealed the shape of the LLR was significant independent predictor of recurrence AF. The shape of the LLR is an independent predictor of recurrence after RFA.
