ABSTRACT
Background:
The role of left atrial appendage occlusion (LAAO) for atrial fibrillation patients that during oral anticoagulant therapy (OAC) suffer from ischemic events or present LAA sludge, and the best postinterventional anticoagulant regimen, need to be defined. We present our experience with a hybrid approach of LAAO+ lifelong OAC therapy in this cohort of patients.Methods:
Out of 425 patients treated with LAAO, 102 underwent LAAO because, despite OAC, suffered from ischemic events or presented with LAA sludge. Patients without high bleeding risk were discharged with the aim of maintaining lifelong OAC. This cohort was then matched to a population who underwent LAAO in primary ischemic events prevention. The primary endpoint was the composite of all-cause death and major adverse cardiovascular events consisting of ischemic stroke, systemic embolism (SE), and major bleeding.Results:
Procedural success was 98%, and 70% of patients were discharged with anticoagulant therapy. After a median follow-up of 47.2 months, the primary endpoint occurred in 27 patients (26%). At multivariate analyses, coronary artery disease (OR 5.1, CI 1.89-14.27, p = .003) and OAC at discharge (OR 0.29, CI 0.11-0.80, p = .017) were associated with the primary endpoint. After propensity score matching, no significant difference was found in the survival free from the primary endpoint according to the indication for LAAO (p = .19).Conclusions:
In this high-ischemic risk cohort, LAAO + OAC seem a long-term safe and effective therapeutical approach, with no difference in the survival free from the primary endpoint according to the indication for LAAO in a matched cohort.
