我们报告一位18岁的男性，术后出现外侧隧道（LT）全腔静脉连接（TCPC）和室上性心动过速（SVT）。LT TCPC后的患者具有复杂的缝合线和LT中相当大面积的受损心肌，这可能成为心动过速的复杂致心律失常基质。LT和心房的详细三维（3D）标测对于成功消融非常重要。在该患者中，使用LT内的超高密度3D标测系统成功完成了两种类型复杂心动过速的导管消融。
We report a case of an 18-year-old male with a postsurgical lateral tunnel (LT) total cavopulmonary connection (TCPC) and supraventricular tachycardia (SVT). Patients after an LT TCPC have complicated suture lines and a considerable area of damaged myocardium in the LT, which could become a complex arrhythmogenic substrate of tachycardias. Detailed three-dimensional (3D) mapping of the LT and atrium is important for a successful ablation. In this patient, successful catheter ablation of two types of complex tachycardias was accomplished using an ultra-high density 3D mapping system inside the LT.
