DOACs Offer Safer Profile but No Added Efficacy in Preventing Device-Related Thrombosis After LAAO
This news is covered by the Medical Dialogues Bureau present at the TCT Conference 2025, being held in San Francisco, USA.
Short-term use of direct oral anticoagulants (DOACs) following left atrial appendage closure (LAAC) did not significantly reduce device-related thrombosis (DRT) compared with dual antiplatelet therapy (DAPT).
However, DOACs were associated with a notably better safety profile, primarily due to reduced bleeding events, based on findings from the ANDES trial presented at TCT 2025, San Francisco and simultaneously published in Circulation.
The ANDES trial, the largest of its kind, was conducted across 13 centers in Canada and Europe between 2018 and 2025.
Josep Rodés-Cabau of Laval University, Quebec, led the study aimed to identify the optimal short-term antithrombotic strategy following LAAC in patients with non-valvular atrial fibrillation (NVAF).
