We describe the first case of the use of pulsed-field ablation (PFA) to treat focal atrial tachycardia (FAT) in a pediatric patient.
An 11-year-old girl with obesity was referred to our center for ablation of incessant atrial tachycardia. The earliest atrial activation was shown to be present in the left superior pulmonary vein. Radiofrequency ablation of FAT seems to be associated with a lower success rate and, especially, with a higher complication rate than in adult patients.
We performed ablation by means of a novel nonthermal energy source (PFA) that is able to reduce the risk of complications due to injury to anatomic structures surrounding the heart. After the first application, stable sinus rhythm was restored.
PFA can be used to treat FAT arising from pulmonary veins in young children as a good alternative to RFA ablation, thereby reducing the risk of potential procedure-related complications.
我们描述了首例使用脉冲场消融（PFA）治疗小儿局灶性房性心动过速（FAT）的病例。
一名肥胖的 11 岁女孩因无休止的房性心动过速被转诊至我们中心进行消融治疗。最早的心房激活显示存在于左上肺静脉。与成人患者相比，FAT 的射频消融似乎与较低的成功率相关，特别是与较高的并发症发生率相关。
我们使用一种新型的非热能源（PFA）进行消融，这种能源能够降低由于心脏周围解剖结构损伤而导致并发症的风险。第一次应用后，稳定的窦性心律得到恢复。
PFA 可用于治疗来自小儿肺静脉的 FAT，作为 RFA 消融的一种替代方法，可降低潜在的与手术相关的并发症的风险。
