Cryoballoon antral pulmonary vein isolation vs contact force-sensing radiofrequency catheter ablation for pulmonary vein and posterior left atrial isolation in patients with persistent atrial fibrillation

The role of cryoballoon ablation (CBA) for antral pulmonary vein isolation (APVI) has not been well established in persistent atrial fibrillation (PerAF). Isolation of the left atrial posterior wall (BOX) after APVI has been suggested to improve the efficacy of radiofrequency catheter ablation (RFA) in PerAF.

Publication date: Available online 16 November 2019Source: Journal of Pharmacological SciencesAuthor(s): Xin Cao, Yoshinobu Nagasawa, Chengshun Zhang, Hanxiao Zhang, Megumi Aimoto, Akira TakaharaAbstractAtrial dilation is an independent risk factor for the development of atrial fibrillation (AF) and modulates the efficacy of anti-AF drugs, leading to the unsatisfactory control of AF. Pre-clinical studies showed anti-AF effects of acehytisine, a multi-ion channel inhibitor, in atria without structural and/or electrophysiological abnormalities, but information is limited regarding its anti-AF efficacy in dilated atria. We ev...

This study aimed to indicate the risk factors of atrial fibrillation (AF) in thyrotoxic patients receiving radioactive iodine (RAI) therapy after antithyroid drug and other medication. Methods This study was a retrospective cohort study. Thyrotoxic patients were divided into two groups, with or without AF. Clinical features were retrospectively analyzed. Univariate and multivariate analyses of data from thyrotoxic patients were performed to evaluate the probability of AF. Results The following clinical factors were found to be correlated with AF: age, gender, duration of hyperthyroidism, coronary artery disease, hype...

ConclusionsMost patients with POAF were asymptomatic but their presentation or outcomes were similar with symptomatic patients. One in four discharged patients was prescribed anticoagulation and the CHADS2-VASC score was not associated with this decision. These findings have important implications for practice and future research. There is a need to better delineate the risk associated with transient versus persistent POAF, symptomatic versus asymptomatic POAF, as well as for clinical trials to determine optimal strategies to improve their outcomes.

Non –vitamin K antagonist oral anticoagulants (NOACs), such as dabigatran, are widely used to prevent ischemic stroke in patients with nonvalvular atrial fibrillation. Nonetheless, stroke occurs in 1–2% of patients, and the use of NOACs may increase the bleeding risk for patients who are receiving a cute treatment of intravenous thrombolysis (IVT) or endovascular thrombectomy (EVT). Idarucizumab, a monoclonal antibody developed to bind dabigatran, has been proven safe and effective for patients with uncontrolled bleeding or for patients planning to receive emergent procedures.

Atrial fibrillation (AF) is the most common arrhythmia and poses a substantial economic burden due to associated thromboembolic complications. Screening for AF may theoretically be effective, but there is no consensus regarding the optimal screening method because the available tools are either invasive or not cost-effective. Recently, smartwatch industry has received a surge of interest for this purpose by introducing technologies such as photoplethysmography, artificial intelligence, and actual electrodes taking an electrocardiogram to measure and analyze heart rate and rhythm with relatively acceptable accuracy. Combine...
