Zusammenfassung
Bei Patienten mit paroxysmalem Vorhofflimmern ist derzeit die Punkt für Punkt HFS-basierte PVI der Goldstandard. Die Erfolgsraten sind mit rund 80 % während eines Nachbeobachtungszeitraumes von 5 Jahren hoch. Jedoch sind Zweiteingriffe häufig. Die Pulmonalvenenisolation mittels Kälteballon ist ein etabliertes Verfahren, das bei vergleichbarer Sicherheit und Effektivität deutlich einfacher durchführbar ist. Neue Technologien sind in Entwicklung mit dem Ziel, den Eingriff noch sicherer, effektiver und einfacher zu gestalten. Vor dem Hintergrund der hohen Erfolgsraten bei paroxysmalem VHF und der Progressionsrate zu persistierendem Vorhofflimmern wird eine frühzeitige Ablation empfohlen.
Abstract
The gold standard in ablation of paroxysmal atrial fibrillation (PAF) is radiofrequency (RF) based point by point pulmonary vein isolation (PVI). In the majority of patients with PAF (80 %) PVI can restore stable SR even during long-term follow-up of up to 5 years. However multiple procedures are often required. Cryo-balloon based PVI is an established technique. Safety and efficacy are comparable to RF ablation. Due to the high success rates in patients with PAF and the progression rate to persistent atrial fibrillation (AF) an early intervention is recommended as implemented in the latest guidelines for AF treatment.
