Zusammenfassung

Die Lungenvenen gelten seit Langem als Hauptquelle atrialer Trigger, und ihre Isolierung ist zum Eckpfeiler der Ablation von Vorhofflimmern geworden. Die radiofrequenzbasierte Pulmonalvenenisolation (PVI) ist jedoch technisch anspruchsvoll, und die langfristigen Erfolgsraten sind begrenzt. In diesem Artikel werden mehrere vielversprechende neue Mappingtechniken beschrieben, die darauf abzielen, die Mechanismen besser zu verstehen, die der Entstehung und Aufrechterhaltung von Vorhofflimmern zugrunde liegen, und effektivere Ablationsstrategien zu entwickeln.

Abstract

The pulmonary veins have been recognized as the primary source of atrial triggers, and their isolation has become the cornerstone for ablation of atrial fibrillation. However, long-term success rates after pulmonary vein isolation (PVI) are limited. Several promising new mapping techniques are described in this article, aiming to better understand the mechanisms underlying the induction and maintenance of atrial fibrillation and to develop more effective ablation strategies.
