BACKGROUND: Direct oral anticoagulants (DOACs) are contraindicated in patients with atrial fibrillation (AF) and mechanical cardiac valves. However, safety and efficacy are controversial in patients with biological cardiac valves.
OBJECTIVE: We report the safety and feasibility of periprocedural and long-term treatment with DOACs in patients with biological valves undergoing ablation for AF.
METHODS: A total of 127 patients with AF and biological cardiac valve undergoing CA on uninterrupted DOAC were matched by gender and age with 127 patients with AF and biological cardiac valves undergoing CA on uninterrupted warfarin. All patients were anticoagulated for at least 3-4 weeks prior to ablation with either rivaroxaban (70%) or apixaban (30%), which were continued for at least 3 months and subsequently based on CHA2DS2-VASc score.
RESULTS: Mean age of the study population was 63.0 ± 10.9 with 66% being male. The majority of patients on NOACs had aortic valve replacement (59%), while mitral valve was replaced in 41% of patients, which did not differ from the matched cohort on coumadin (aortic valve 57% and mitral valve 43%, (p = 0.8) (p = 0.8), respectively). The CHADS2 score was ≥ 2 in 90 patients (71.0%) on DOAC and 86 patients in (68%) the control (p = 0.6) group. Patients underwent ablation predominantly with uninterrupted rivaroxaban [89 (70%)], while the remaining 38 patients (30%) underwent ablation while on apixaban. Two groin hematomas were observed periprocedurally in both groups. No stroke/transient ischemic attack (TIA) was observed both periprocedurally and at long-term follow-up in either group.
CONCLUSION: Periprocedural and long-term administration of DOACs in patients with biological cardiac valves undergoing AF ablation appears as safe as warfarin therapy.
