Abstract

AbstractIntroductionWe describe the first case of the use of pulsed‐field ablation (PFA) to treat focal atrial tachycardia (FAT) in a pediatric patient.MethodsAn 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.ResultsWe 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.ConclusionsPFA 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.
