This is a case of atrial tachycardia 2 years after pulmonary transplantation. After excluding right atrial involvement, tachycardia origin was located in a scar region medial to the anastomosis of the left inferior pulmonary donor vein. Tachycardia mechanism was microreentry. Noninvasive electrocardiographic mapping performed before the ablation procedure matched with results of invasive Carto mapping and predicted both tachycardia mechanism and origin. We discuss arrhythmia mechanism found after pulmonary transplantation and benefit of noninvasive electrocardiographic mapping for procedure planning.
这是一例肺移植后 2 年发生的房性心动过速。在排除右心房受累后，心动过速起源于吻合线内侧的左肺下静脉供体的瘢痕区。心动过速机制为微折返。消融前进行的无创性心电图标测与心内 Carto 标测结果相匹配，预测了心动过速的机制和起源。我们讨论了肺移植后发现的心律失常机制以及无创性心电图标测对手术规划的益处。
