Left Atrial Appendage Transcatheter Occlusion with AMPLATZER™ Amulet™ Device: Real Life Data with Mid-Term Follow-Up Results

Conclusion: We concluded that LAA occlusion using the Amulet ™ LAA occluder can be performed with high procedural success and acceptable outcomes.Resumo Fundamento: A oclus ão do apêndice atrial esquerdo (AAE) é uma terapia alternativa para pacientes com fibrilação atrial que tenham alto risco embólico e contraindicações à terapia anticoagulante. Objetivo: Avaliar a viabilidade, segurança e resultados de médio prazo da oclusão percutânea do AAE, incluindo a trombose relacionada à prótese. Métodos: Sessenta pacientes consecutivos que foram submetidos à oclusão percutânea do AAE com a prótese AMPLATZER ™ Amulet ™ de setembro de 2015 a mar ço de 2018 foram incluídos no estudo. Os pacientes foram acompanhados por 21 ± 15 meses (mediana - 20 meses, intervalo interquartílico - 9 a 27 meses). A avaliação pós-procedimento foi feita no 1º, 6º e 12º mês. Os pacientes foram examinados clinicamente e um ecocardiograma transesofágic o foi realizado a cada visita. A condição de normalidade das variáveis foi avaliada por meio do teste de Kolmogorov-Smirnov. Os valores de p3 mm) na avalia ção do 1º mês, que desapareceu no 12º mês de seguimento. Conclusão: Concluiu-se que a oclusão do AAE com o ...

Authors: Cohen AT, Hunt BJ Abstract The direct oral anticoagulants (DOACs) have transformed the management of thrombotic disorders. Large clinical trials have demonstrated that DOACs can replace vitamin K antagonists (VKAs) in the 2 existing major indications for anticoagulation: the prevention of stroke in atrial fibrillation and the acute treatment and secondary prevention of venous thromboembolism (VTE); this literature is widely known. In this article, we will concentrate on the less well-discussed benefits of the use of DOACs-using low doses as primary and secondary prophylaxis in both venous and arterial thro...

Authors: Kimpton M, Siegal DM Abstract A 77-year-old man with atrial fibrillation and a CHA2DS2Vasc score of 6 for hypertension, age, diabetes, and previous stroke is brought to the emergency department with decreased level of consciousness. He is anticoagulated with rivaroxaban (a direct oral factor Xa inhibitor [FXaI]) and received his last dose about 4 hours before presentation. Urgent computed tomography of the head shows intracerebral hemorrhage. Because of his previous stroke, the patient's family is concerned about treating the bleed with pharmacological agents that may increase the risk of stroke. What are ...

Atrial fibrillation (AF) is associated with a substantially higher risk of thromboembolism, particularly stroke events, resulting in significant morbidity and mortality. Oral anticoagulation (OAC), while effective in reducing embolic events in AF patients, is associated with an increased bleeding risk. Thus, not all patients with AF are candidates for OAC and some are only candidates for OAC in the short term. Of the available nonpharmacologic strategies for the management of AF, left atrial appendage occlusion (LAAO) has emerged as a potential approach for reducing the risk of systemic thromboembolism in AF patients eligi...

CONCLUSIONS: Compared to warfarin, NOACs were associated with a significantly lower risk of adverse events, with heterogeneity in treatment effects among different age strata. Overall, the clear safety signal in favor of NOACs over warfarin was evident irrespective of age strata, being most marked in the most elderly. PMID: 31809694 [PubMed - as supplied by publisher]

AbstractThe best strategy in atrial fibrillation (AF) after  >  12 months after an acute coronary syndrome or in patients with chronic coronary syndrome without an indication for interventional revascularization remains unclear. European guidelines generally recommend therapy with oral anticoagulation (OAC) alone, whereas North American guidelines advise com bination therapy consisting of OAC plus antiplatelet therapy in some patients. We performed a meta-analysis of available trials comparing these treatment strategies. The primary endpoint was major adverse cardiac events (MACE), secondary endp...

AbstractSeveral studies have explored the use of NOACs compared with vitamin K antagonists (VKAs) in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF); and therefore, we aimed to compare the efficacy and safety outcomes of NOACs with VKAs in this population. We systematically searched the PubMed and Embase databases until August 5, 2019 for studies that compared the effect of NOACs with VKAs in patients with HCM and AF. The risk ratios (RRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. A total of four observational studies were included in this meta-analysis. Over...

CONCLUSION:  In AF patients with malignancy, NOACs appear at least as effective as VKAs in preventing thrombotic events and reduce intracranial bleeding. NOACs may represent a valid and more practical alternative to VKAs in this setting of high-risk patients. PMID: 31785599 [PubMed - as supplied by publisher]

CONCLUSIONS: HAS-BLED is a balanced bleeding risk assessment tool in terms of sensitivity and specificity, whereas the European score, ABC, and mOBRI are high sensitivity tools and ORBIT, ATRIA, Shireman, and GARFIELD-AF are high specificity tools. PMID: 31782613 [PubMed - as supplied by publisher]

Angelika Batta, Bhupinder S Kalra, Raj KhirasariaNeurology India 2019 67(5):1200-1212 As the population is aging, clinicians are coming across more patients with atrial fibrillation and venous thromboembolism requiring anticoagulation to prevent stroke and systemic embolisms. Due to a high prevalence and unfavorable consequences, managing thromboembolic diseases have become areas of clinical concern. Traditional anticoagulants like heparin, low molecular weight heparin and warfarin have been used for the prevention and treatment of venous and arterial thromboses. But, issues of bleeding, parenteral route of administration...
