Abstract
In adults with congenital heart disease, atrial fibrillation occurs at a lower age due to the increased atrial stress compared to structurally normal hearts. The ablation target thus results from the underlying heart defect and the specific arrhythmia: in the case of atrial fibrillation, pulmonary vein isolation with left atrial substrate modification can be performed safely and effectively taking into account the individual cardiac lesion, which is often related to difficult transseptal access. This case is a representative example of catheter ablation of atrial fibrillation in a patient with a functional univentricular heart using intracardiac echocardiography-guided double transseptal puncture.
Zusammenfassung
Bei Erwachsenen mit angeborenem Herzfehler tritt Vorhofflimmern, bedingt durch die vermehrte atriale Belastung im Vergleich zu strukturell Herzgesunden, in jüngerem Lebensalter auf. Das Ablationsziel resultiert somit aus dem zugrunde liegenden Herzfehler und der spezifischen Herzrhythmusstörung. Eine Pulmonalvenenisolation, ggf. mit linksatrialer Substratmodifikation ist unter Berücksichtigung des zugrunde liegenden Herzfehlers ein sicheres und wirksames Verfahren, ist jedoch häufig mit einem erschwerten transseptalen Zugang verbunden. Der hier vorgestellte Fall ist ein repräsentatives Beispiel für die Katheterablation von Vorhofflimmern bei einem Patienten mit funktionell univentrikulärem Herzen unter Anwendung einer intrakardial-echokardiographisch geführten doppelten transseptalen Punktion.
