AUSTIN, Texas, 3. September 2026 /PRNewswire/ -- Das Texas Cardiac Arrhythmia Institute (TCAI) am St. David's Medical Center hat sich kürzlich als erste Einrichtung des Landes an einer klinischen Studie beteiligt, in der die Sicherheit sowie Wirksamkeit eines Mapping- und Pulsfeld-Ablationssystems der nächsten Generation zur Behandlung von Patienten mit paroxysmalem sowie persistierendem Vorhofflimmern untersucht werden. Andrea Natale, M.D., F.H.R.S., F.A.C.C., F.E.S.C., geschäftsführender medizinischer Leiter des TCAI und globaler Studienleiter der Studie, führte den ersten Eingriff durch.

Vorhofflimmern, die häufigste Form von Herzrhythmusstörungen, betrifft weltweit Millionen von Menschen. Es tritt auf, wenn die beiden Vorhöfe des Herzens zu schnell und unregelmäßig schlagen. Paroxysmales Vorhofflimmern ist eine Herzrhythmusstörung, deren Symptome höchstens sieben Tage andauern, während persistierendes Vorhofflimmern eine anhaltende Herzrhythmusstörung ist, die länger als eine Woche andauert. Eine frühzeitige Behandlung von paroxysmalem und persistierendem Vorhofflimmern kann das Risiko für Blutgerinnsel, Schlaganfall und Herzinsuffizienz senken – und möglicherweise verhindern, dass die Erkrankung in eine permanente Form übergeht.

„Die Pulsfeldablation stellt einen der bedeutendsten Fortschritte in der Elektrophysiologie seit Jahrzehnten dar, und diese klinische Studie wird Ärzten weltweit helfen, die Sicherheit und Wirksamkeit dieser Technologie besser zu verstehen", sagte Dr. Natale. „Das Texas Cardiac Arrhythmia Institute ist weiterhin führend in der Behandlung von Herzrhythmusstörungen und trägt dazu bei, Technologien voranzutreiben, die die Zukunft der Elektrophysiologie prägen werden."

Das neuartige Kathetersystem nutzt elektrische Felder, um gezielt Herzgewebe zu veröden, ohne dabei die bei herkömmlichen Ablationsverfahren eingesetzte extreme Hitze oder Kälte zu verwenden, wodurch das Risiko einer Schädigung umliegender Strukturen verringert wird. Das System verfügt über eine fortschrittliche 3D-Herzkartierungstechnologie, die eine detaillierte Darstellung der elektrischen Aktivität des Herzens liefert und Ärzten ermöglicht, die Position des Katheters und den Kontakt zum Gewebe vor und nach der Energieabgabe zu visualisieren. Bei einem herkömmlichen Ablationsverfahren wird ein Katheter in das Innere des Herzens eingeführt, wo er mithilfe extremer Hitze oder Kälte Gewebe zerstört, das mit Herzrhythmusstörungen in Zusammenhang steht. Dabei besteht ein erhöhtes Risiko, dass umliegende Strukturen beschädigt werden.

Das TCAI ist ein hochmodernes elektrophysiologisches Zentrum, das sechs mit modernster Technologie ausgestattete Labore umfasst, in denen eine Gruppe renommierter kardialer Elektrophysiologen eine große Anzahl der komplexesten elektrophysiologischen Verfahren durchführt.
