Vorhofohrverschluss – Schritt für Schritt

Thromben im linken Vorhofohr infolge von Vorhofflimmern sind die häufigste Ursache embolischer Schlaganfälle [1]. Antikoagulanzien sind eine wirksame Prophylaxe [2]. Patienten mit nicht-valvulärem Vorhofflimmern mit Kontraindikationen gegen eine Antikoagulation können von einem Vorhofohrverschluss profitieren [3].

Abstract

Thrombus formation due to atrial fibrillation is the most common cause of embolic stroke. Anticoagulation offers an effective prophylaxis. However, anticoagulation in turn has an inherent increased risk of bleeding. Patients with non-valvular atrial fibrillation who have contraindications for anticoagulation may profit from a closure of the left atrial appendage. The most commonly and best studied devices for this are the WATCHMAN™ and the AMPLATZER Amulet™ Occluders.

In this How-To article, the aim is to offer a general overview of the indications, contraindications and complications as well as the implantation and postoperative management of patients receiving LAA closure by example of the WATCHMAN FLX™ Occluder.
