Filter by:This is a cohort study to evaluate algorithms for mapping atrial fibrillation by mapping atrial structure and mapping electrical activity to detect focal and rotational activity.
According to current guidelines for non-valvular atrial fibrillation treatment, the first line drugs are non-vitamin K oral anticoagulants (NOACs), which are preferred over vitamin K antagonists (VKAs). However, it is not clearly confirmed, how the success of NOACs approval trials (ROCKET-AF (rivaroxaban), RE-LY (dabigatran) and ARISTOTLE (apixaban) reflects on real-life clinical practice. The aim of this study is to assess treatment of AF patients with oral anticoagulants (OACs) in an academic and district hospital, with regard to inclusion/exclusion criteria used in the clinical trials.
The aim of this prospective randomized study was to assess the efficacy of ablation of the ganglionated plexi localized in the epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.
The aim of this prospective randomized double-blind study was to compare the efficacy of new pharmaceutical composition containing botulinum toxin injection in epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.
Preliminary data suggest that: 1. a different risk of mortality, as assessed by the Multidimensional Prognostic Indices (MPI), may influence the anticoagulant prescription in older subjects with Atrial Fibrillation (AF); 2. the presence of multidimensional impairment, disability and multi-morbidities are usually not included in the decision algorithm of the more appropriate treatments in older patients with AF; 3. considering the prognostic information, as calculated by the MPI, can be useful to physicians in identifying older patients with AF that can benefit from anticoagulant treatment in term of increased survival.
There are 10 million atrial fibrillation (AF) patients in China, and the patients are risk of stroke, heart failure and sudden death. Persistent AF is still a refractory disease, and single catheter ablation only has a success rate around 30-50%. Hybrid strategy consisting of thoracoscopic epicardial ablation and transvenous endocardial ablation seems to be an attractive procedure to improve the treatment of persistent AF. However, only a few centers reported their preliminary results, and the conclusions are controversial. The investigator previously reported a minimally invasive surgical ablation from left thoracoscope only and achieved good results. Recently, the investigator successfully explored a hybrid procedure combing this unique surgical technique and transvenous catheter ablation. Here, the investigator present a study to evaluate the efficacy and safety of this novel hybrid procedure. The hypothesis is that a hybrid approach is more efficient than surgical ablation alone in the treatment of persistent AF. This study is a non-randomized controlled study within a single institution. Isolated persistent AF patients admitted to the cardiovascular surgery department of Shanghai Xinhua Hospital will be screened for enrollment of this study. The study will recruit 180 patients in total. Based on their own willingness, the patients will be divided into hybrid group and minimally invasive (MIS) group. The MIS group patients only have surgical ablation surgery from left thoracoscope as the investigator reported before, while the hybrid group patients will have additional transvenous catheter ablation after the surgical ablation is done during the same operation. The ratio of hybrid to MIS group is expected to be 1:1, so that each group contains 90 patients. The perioperative data is collected, and the patients will be followed for 6 months. The primary outcome is the rate of sinus rhythm at 6 months post operation. The secondary outcomes include off antiarrhythmic drug rate, perioperative complications, major cardiovascular events, stroke, left ventricular systolic function, medical expense, serum brain natriuretic peptide level and quality of life. The aim is to evaluate the efficacy and safety of this novel hybrid procedure, therefore to provide more evidence of the hybrid strategy in the treatment of persistent AF.
The goal of this pilot study is to explore the efficacy of chloroquine in terminating persistent AF and assess its potential role as a pharmacological cardioversion agent for the management of AF.
This randomized prospective study compared three ablation strategies in patients with longstanding persistent atrial fibrillation (LPeAF). It also explored the best procedural endpoint from among the following: circumferential pulmonary vein isolation (PVI)+left atrial (LA) linear lesions (roof line, mitral isthmus)+complex fractionated atrial electrogram (CFAE) ablation, PVI+LA linear lesions +cavotricuspid isthmus (CTI) ablation +CFAE ablation, and PVI+CFAE ablation.
Rationale: Adult patients with congenital heart disease (CHD) with atrial tachyarrhythmias need to be anticoagulated. It is not known whether non-vitamin K antagonist oral anticoagulants (NOAC) in this patient group are efficient and safe. Aim: The purpose of the NOTE registry is to evaluate the efficacy and safety of NOACs for thromboembolic prevention in atrial tachyarrhythmias in adult patients with congenital heart disease (CHD). Methods: In this multicenter prospective registry adult CHD patients with atrial tachyarrhythmias on NOACs (switch from VKA or new on anticoagulants) will be followed for a minimum of two years. Primary efficacy endpoints are defined as thromboembolism, i.e. the composite of ischemic stroke, systemic and pulmonary embolism and intracardiac thrombosis, and as the composite of stroke and systemic embolism. Primary safety endpoint is defined as major bleeding according to the ISTH criteria. Secondary endpoints include each thromboembolic or bleeding event analysed separately, all-cause mortality, therapy adherence, quality of life, risk assessment of stroke and evaluation of natural history of atrial tachyarrhythmia in adult CHD patients. Primary endpoint assessment will be performed with a per protocol analysis, and demonstrated as Kaplan Meyer estimates of event free survival and event rates per year.
The purpose of this study is to compare DUA (discrete uptake accumulations) of mIBG activity in patients with different forms of atrial fibrillation and within a sub-group of healthy subjects.
