dabigatran ablation

Left atrial or left atrial appendage thrombosis (LAT) is contraindicated for cardiac ablation (CA) or cardioversion (CV) of atrial fibrillation (AF). This study was aimed to compare the frequency of LAT detected by transesophageal echocardiography (TEE) before CA or CV in patients with AF treated with direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs). We searched PubMed, Scopus, Web of Science, and Cochran Library databases from inception through July 13, 2023 to select studies reporting data on LAT identification before CA or CV using TEE in patients with AF treated with DOACs or VKAs...

BACKGROUND AND OBJECTIVES: Long-term oral anticoagulation (OAC) following successful catheter ablation of atrial fibrillation (AF) remains controversial. Prospective data are missing. The ODIn-AF study aimed to evaluate the effect of OAC on the incidence of silent cerebral embolic events and clinically relevant cardioembolic events in patients at intermediate to high risk for embolic events, free from AF after pulmonary vein isolation (PVI). METHODS: This prospective, randomized, multicenter, open-label, blinded endpoint interventional trial enrolled patients who were scheduled for PVI to treat paroxysmal or persistent AF...

BACKGROUND: The safety and efficacy of an uninterrupted direct anticoagulation (DOAC) strategy during catheter ablation (CA) for atrial fibrillation (AF) has not been fully investigated with different ablation techniques. METHODS: We evaluated consecutive AF patients undergoing catheter ablation with three different techniques. All patients were managed with an uninterrupted DOAC strategy. The primary endpoint was the rate of periprocedural thromboembolic and bleeding events...

Strokes are a common cause of death. Cardiovascular disease, including atrial fibrillation and atrial flutter, is a frequent cause of ischemic strokes. A 64-year-old man developed isolated dysarthria without any other neurologic manifestations as the presentation of an ischemic stroke resulting from occlusion to the middle cerebral artery and affecting the cortex supplied by the artery. He was discovered to be in atrial flutter which was determined to be the likely etiology of his stroke. He was hospitalized and anticoagulated with heparin; as an outpatient, his anticoagulation was maintained with the direct oral anticoagulant apixaban...

BACKGROUND AND AIMS: Since the introduction of direct oral anticoagulant (DOAC) for atrial fibrillation (AF) therapy, inappropriate and/or underdosing of these drugs has been a major clinical challenge. We evaluated the characteristics of AF patients treated with inappropriate and low dose DOACs. METHODS: AF patients treated with inappropriate and low dose DOACs from October 2021 to December 2021 were evaluated from the Prospective French National Registry (PAF)...

AIMS: In patients undergoing catheter ablation for atrial fibrillation (AF), direct oral anticoagulants (DOACs) are as effective and safe as the vitamin K antagonist (VKA) warfarin. Phenprocoumon has a different pharmacokinetic profile compared with warfarin and is the most used VKA in Germany. The aim of the study was to compare DOAC with phenprocoumon. METHODS AND RESULTS: In this retrospective single-centre cohort study, 1735 patients who underwent 2219 consecutive catheter ablations for AF between January 2011 and May 2017 were included...

BACKGROUND: Based on the few available studies on the prognostic benefit of using direct oral anticoagulants (DOACs) after atrial fibrillation (AF) ablation. Therefore, this study aimed to evaluate the prognostic differences between patients who underwent radiofrequency ablation (RFA) and those without RFA taking DOACs. METHODS: This is a multicenter retrospective cohort study enrolling 6137 patients with non-valvular AF (NVAF) at 15 hospitals in China. Patient information was collected through a mean follow-up of 10 months and medical record queries...

BACKGROUND: Unfractionated heparin (UFH) is used as an anticoagulant during the atrial fibrillation (AF) ablation procedure to prevent the occurrence of thromboembolic events. Guidelines recommend an activated clotting time (ACT) greater than 300 s (s) based on studies of patients treated with vitamin K antagonist (VKA) for their AF. However, direct oral anticoagulants (DOACs) have supplanted VKAs in AF and are now used as first-line therapy. It is recommended not to interrupt them during the procedure, which could interfere with the ACT measures...

BACKGROUND: Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. Totally thoracoscopic ablation (TTA) is a surgical treatment showing a high success rate as a hybrid procedure with radiofrequency catheter ablation to control AF. This study compared the early complications of warfarin and non-vitamin K antagonist oral anticoagulants (NOACs) in patients who underwent TTA. METHODS: This single-center retrospective cohort study enrolled patients who underwent planned TTA for AF from February 2012 to October 2020...

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed...

BACKGROUND: Direct oral anticoagulants (DOACs) have increasingly become an alternative to warfarin in atrial fibrillation (AF) patients. Nonetheless, data on the effectiveness and safety of DOACs in periprocedural of catheter ablation (CA) in real-world practice was relatively rare. METHODS AND RESULTS: 3385 AF patients underwent initial CA and never used oral anticoagulant before enrollment between April 2013 and December 2018 were involved from China Atrial Fibrillation (China-AF) Registry...

Atraumatic splenic rupture (ASR) is a rare condition mostly associated with neoplastic, infectious, and inflammatory diseases. ASR associated with drug treatment is even rarer. In this case report, we highlight an unusual complication of the direct oral anticoagulant rivaroxaban. A 64-year-old male patient was admitted to the emergency department with complaints of faintness and diffuse abdominal cramps. The patient had no history of recent trauma. Clinical examination revealed hemodynamic instability with a moderate response to filling and mild abdominal discomfort on palpation...

BACKGROUND: Uninterrupted use of oral anticoagulants before atrial fibrillation (AF) ablation can reduce the incidence of perioperative thromboembolic events. However, the effect of new oral anticoagulants on activated clotting time (ACT) in response to heparin during AF ablation in Chinese populations remains unknown. The aim of the present retrospective study was to investigate the value of ACTs in response to intraoperative heparin administration in patients using dabigatran or rivaroxaban...

INTRODUCTION: Some patients with atrial fibrillation (AF) develop left atrial appendage thrombus (LAAT) despite receiving anticoagulant treatment. Different scores were proposed to evaluate thromboembolic risk in patients with AF. Risk stratification according to sex is common in clinical practice. OBJECTIVE: We aimed to identify predictors of LAAT separately in men and women treated with dabigatran or rivaroxaban. PATIENTS AND METHODS: This retrospective study included 1256 patients (women, 38%) with AF who underwent transesophageal echocardiography before electrical cardioversion or catheter ablation between January 2013 and December 2019 and received dabigatran or rivaroxaban for at least 3 weeks...

OBJECTIVE: This study aimed to investigate the effectiveness and safety of idarucizumab for periprocedural cardiac tamponade after catheter ablation of atrial fibrillation (AF) in patients treated with dabigatran. METHODS: We retrospectively studied 28 patients who received catheter ablation of AF and developed periprocedural cardiac tamponade. Patients were divided into two groups: control group (14 cases) and the study group (14 cases). Patients in the control group were administered warfarin bridged with low molecular weight heparin, while patients in the study group were given dabigatran for anticoagulation...

BACKGROUND: Idarucizumab, a dabigatran-specific reversal agent, was launched in Japan in 2016. The J-Dabigatran Surveillance 2 study was designed to assess the characteristics and outcomes of dabigatran-treated patients after the launch of idarucizumab. METHODS: Patient characteristics and outcomes, including thromboembolic and bleeding events, of dabigatran-naïve patients with non-valvular atrial fibrillation (NVAF) who received dabigatran etexilate [110 mg or 150 mg twice-daily (b...

BACKGROUND: Atrial fibrillation (AF) and flutter (AFl) increase the risk of thromboembolism. The aim of the study was to assess the prevalence of left atrial thrombus (LAT) in AF/AFl in relation to oral anticoagulation (OAC). METHODS: LATTEE (NCT03591627) was a multicenter, prospective, observational study enrolling consecutive patients with AF/AFl referred for transesophageal echocardiography before cardioversion or ablation. RESULTS: Of 3109 patients enrolled, 88% were on chronic, 1...
