Interventioneller Vorhofohrverschluss

ZUSAMMENFASSUNG

Bedauerlicherweise existieren bisher keine randomisierten Studiendaten hinsichtlich des Stellenwerts eines Vorhofohrverschlusssystems (LAAC: „left atrial appendage closure“) im Vergleich zu oralen Antikoagulanzien (OAK) bei CKD-Patienten (CKD: „chronic kidney disease“). Eine derartige Studie (WATCH AFIB in CKD) wurde wegen geringer Rekrutierungszahlen eingestellt. Aus den im Beitrag angesprochenen Beobachtungsstudien kann allerdings eine gute Sicherheit und Effektivität der Therapie abgeleitet werden. In Anbetracht der unzureichenden Evidenz sollte bei VHF Patienten (VHF: Vorhofflimmern) mit CKD bis zu einer glomerulären Filtrationsrate (GFR) von 30 ml/min/1,73 m² primär eine NOAK-Therapie (NOAK: neue OAK) verordnet werden. Im Falle von Blutungen kann dann gemäß Leitlinienempfehlung eine LAAC alternativ angeboten werden. Im Falle von Patienten mit dialysepflichtiger CKD muss eine individuelle Entscheidung getroffen werden, ob und wie eine Thromboembolieprophylaxe durchgeführt werden soll.
