Zusammenfassung

Wir berichten über eine 31-jährige Patientin mit einem operativ korrigierten „double outlet right ventricle“ und rezidivierenden Schmalkomplextachykardien. Die elektrophysiologische Untersuchung zeigt eine atriale Tachykardie (AT). Nach Anlage einer linearen Läsion entlang der ermittelten Grenzzone der Narbe, welche mit den Inzisionsstellen der Korrekturoperation korreliert, terminiert die AT spezifisch an der Stelle des im fusionierten Voltage- und Coherent-Map visualisierten kritischen Isthmus nach wenigen Sekunden. Das Coherent-Modul bietet somit große Vorteile durch individuelle Ablationsstrategien.

Abstract

A 31-year-old woman with a surgically corrected double outlet right ventricle and recurrent narrow QRS complex tachycardia was admitted to our hospital. The patient was scheduled for electrophysiology study. Coherent mapping identified the critical isthmus as a slow conduction area within posterolateral intercaval scar tissue. A continuous line of ablation was applied resulting in termination of the atrial tachycardia at the site of the critical isthmus from coherent mapping. Thus, coherent mapping facilitates complex ablation procedures and improves efficacy and efficiency.
