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.
探讨左心房外侧嵴（LLR）的几何形态在射频消融（RFA）术后房颤（AF）复发中的作用。回顾性纳入225例首次接受RFA治疗的AF患者，分为复发组（n = 53）和非复发组（n = 172）。分析临床资料、左心房容积（LAV）及LLR几何形态。复发组的LAV大于非复发组（P < 0.001）。复发组的LLR呈矩形的比例高于非复发组（43% 对77%，P < 0.001）。复发组LLR开口的前后径小于非复发组（P = 0.001），而复发组LLR的长度更长（P = 0.012）。多因素分析显示LLR的形态是房颤复发的显著独立预测因素。LLR的形态是RFA术后复发的独立预测因素。
