We describe a case of a 49-year-old patient with left atrial flutter after atrial fibrillation ablation. Left atrium activation map (CARTO) and entrainment mapping revealed local reentry on the posterior wall of the left atrium, close to the proximal coronary sinus. Arrhythmia was terminated with a single RF application and remained noninducible. However, after 6-weeks follow-up patient presented with a roof line and mitral isthmus - dependent atrial flutters which were successfully ablated.
我们描述了一例49岁患者，在房颤消融术后发生左房扑动。左房激动标测图（CARTO）和拖带标测显示左房后壁靠近冠状窦近端存在局部折返。通过单次射频消融终止了心律失常，且心律失常不再能被诱发。然而，6周随访后，患者出现了依赖于房顶线和二尖瓣峡部的房扑，并成功进行了消融。
