A systematic review and meta-analysis of non-vitamin K antagonist oral anticoagulants vs vitamin K antagonists after transcatheter aortic valve replacement in patients with atrial fibrillation.

Purpose: Transcatheter aortic valve replacement (TAVR) is increasingly carried out in patients with aortic valvular conditions. Atrial fibrillation (AF) is a common comorbidity among patients undergoing TAVR. Despite this, there remains a paucity of data and established guidelines regarding anticoagulation use post-TAVR in patients with AF.
