Abstract
INTRODUCTION: Patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF) require chronic anticoagulation due to a high thromboembolic risk. Evidence supporting use of non-vitamin K oral anticoagulants (NOACs) in patients with HCM remains sparse, and there are no data regarding the use of NOACs in HCM patients undergoing catheter ablation of AF. METHODS: Observational non-randomised study in 4 European Centres. We aimed to investigate the safety and efficacy of NOACs compared with vitamin-K antagonists (VKAs) in patients with HCM undergoing catheter ablation for AF. RESULTS: One hundred thirty-seven HCM patients (mean age 55.0±13.4, 29.1% female) underwent 230 catheter ablations for AF (1.7±1.0 per patient). A total of 55 patients (39.4%) underwent 70 procedures (30.4%) on NOAC, while the remaining were on VKA. Warfarin (97.6%) and rivaroxaban (56.4%) were the most frequently used agents in the respective groups. No procedure-related deaths were reported. We observed no significant difference in the rate of thromboembolism (VKA 0.6%; NOAC 0%; p=1.0) or minor bleeding (VKA 0.6%; NOAC 1.4%; p=0.54). There was a non-significant trend towards a lower incidence of major bleeding (VKA 6.9%; NOAC 1.4%; p=0.09). CONCLUSION: These preliminary data suggest that NOACs are at least as safe and effective as VKAs in patients with HCM undergoing catheter ablation for AF. This article is protected by copyright.
