Case report: Unusual focal atrial tachycardia from the left inferior pulmonary vein in a pediatric patient treated by high-power short duration catheter ablation

Year: 2025

Type: article

Abstract: We describe an unusual case of focal atrial tachycardia (FAT) from the left inferior pulmonary vein (PV) in a 12- year old boy treated successfully by high power short duration (HPSD) ablation. The patient was referred to our center for ablation of incessant FAT with recurrent transient degeneration into atrial fibrillation. The electrophysiological study revealed FAT with a micro-reentrant like activation from the left inferior PV. To reduce the risk of complications to surrounding structures, isolation of the left pulmonary veins was performed using HPSD (65 W, 6-15 s) ablation. During a follow-up period of 12 months, the patient remained in stable sinus rhythm.
