Outcomes and costs of left atrial appendage closure from randomized controlled trial and real-world experience relative to oral anticoagulation

Aims The aim of this study was to analyse randomized controlled study and real-world outcomes of patients with non-valvular atrial fibrillation (NVAF) undergoing left atrial appendage closure (LAAC) with the Watchman device and to compare costs with available antithrombotic therapies.Methods and results Registry data of LAAC from two centres were prospectively collected from 110 patients with NVAF at risk of stroke, suitable and unsuitable for long-term anticoagulation (age 71.3 ± 9.2 years, CHADS2 2.8 ± 1.2, CHA2DS2-VASc 4.5 ± 1.6, and HAS-BLED 3.8 ± 1.1). Outcomes from PROTECT AF and registry study LAAC were compared with warfarin, dabigatran, rivaroxaban, apixaban, aspirin, and no treatment using a network meta-analysis. Costs were estimated over a 10-year horizon. Uncertainty was assessed using sensitivity analyses. The procedural success rate was 92% (103/112). Follow-up was 24.1 ± 4.6 months, during which annual rates of stroke, major bleeding, and all-cause mortality were 0.9% (2/223 patient-years), 0.9% (2/223 patient-years), and 1.8% (4/223 patient-years), respectively. Anticoagulant therapy was successfully stopped in 91.2% (93/102) of implanted patients by 12 months. Registry study LAAC stroke and major bleeding rates were significantly lower than PROTECT AF results: mean absolute difference of stroke, 0.89% (P = 0.02) and major bleeding, 5.48% (P

AbstractThe association between atrial fibrillation (AF) and thromboembolic (TE) complications in left ventricular assist device (LVAD) recipients is controversial, and there is paucity of large-scale data evaluating the impact of AF on early outcomes after device implantation. Using the National Inpatient Sample, we identified hospitalizations where patients underwent LVAD implantation from 2010 to 2015. Multivariate logistic regression was used to evaluate the association of AF on in-hospital outcomes. A total of 18,378 patients (41.7% with AF) underwent LVAD implantation. Patients with AF were older (59.9 vs. 54.0  years,p

Conclusion: Our meta-analysis suggests that uninterrupted DOAC is not superior to VKA in patients undergoing catheter ablation of AF with comparable rates of major bleeding and stroke. PMID: 32056498 [PubMed - as supplied by publisher]

Abstract BACKGROUND: The management of antithrombotic therapy in patients undergoing percutaneous coronary intervention (PCI) with an indication for long-term oral anticoagulant therapy (OAT) is still a matter of debate. We aim to evaluate the safety and the efficacy of dual therapy (DT) compared to triple therapy (TT) in this clinical setting. METHODS: A study level meta-analysis and a review of randomized trials selected using PubMed, Embase, EBSCO, Cochrane database of systematic reviews, Web of Science, and abstract from major cardiology congresses. Six randomized trials with 12,156 patients evaluating th...

CONCLUSION: In a national cohort of Medicare beneficiaries with newly-diagnosed AF, overall oral anticoagulant initiation was lower in blacks and women, with no difference observed by Hispanic ethnicity. Among oral anticoagulant initiators, blacks were less likely to initiate novel DOACs, with no differences identified by Hispanic ethnicity or sex. Identifying modifiable causes of treatment disparities is needed to improve quality of care for all patients with AF. PMID: 32035755 [PubMed - as supplied by publisher]

ConclusionsIn patients with AF and VHD, rates of major bleeding were similar among the DOACs and valve types; however, more patients receiving dabigatran experienced SSE. Further studies are needed to validate these findings.

With safety concerns about increasing bleeding, off-label underdosing of non-vitamin K antagonist anticoagulants (NOACs) is common in East Asian patients with atrial fibrillation (AF). We tried to investigate the pattern of NOAC underdosing and associated clinical outcomes in patients with AF who are indicated for standard dosing. Using the Korean National Health Insurance Service database, we evaluated 16568 patients with a new prescription of NOAC who are indicated for standard NOAC dosing and compared 4536 patients with warfarin with respect to thromboembolic events (ischemic stroke or systemic embolization), all-cause ...

Conclusion: DOAC discontinuation rates varied significantly and appeared related to drug-specific side effects, patient-initiated discontinuation, and bleeding. We observed longer-term administration of apixaban, suggesting that this drug is better tolerated than dabigatran or rivaroxaban. PMID: 32011180 [PubMed - as supplied by publisher]
