The study will try to access the efficacy of atrial pacing, medication and radiofrequency ablation in treating patients with paroxysmal atrial fibrillation and sinus node dysfunction; to identify the response to these treatments in patients with "functional" and organic sinus node dysfunction respectively; to explore the necessity of pacemaker implantation in patients with "functional" sinus node dysfunction. Patients who meet the inclusion criteria will receive pacemaker implantation followed by trial pacing, medication and radiofrequency ablation of AF. Device data will be analyzed to answer the question. And after follow-up of 1 year, lower rate of pacemaker will be set as 40 bpm for patients without AF. The proportion of pacing and patients' tolerance will be analyzed.
Prospective randomized open-label blinded endpoint (PROBE) 2x2 factorial study of metformin extended release up to 750 mg BID and lifestyle and risk factor modification (LRFM) in CIED patients with at least 1 ≥5 minute episode of AF over the prior 3 months. Randomization will be stratified by pacemaker vs. ICD and rhythm at enrollment (sinus rhythm/atrial paced vs. AF).
People: The absolute prevalence of undiagnosed atrial fibrillation in individuals over 60 years of age is 2.2%, equivalent to 20.1% of the overall prevalence of AF and there is not sufficient evidence regarding the procedures that may be most effective for achieving an early diagnosis of AF and reducing the associated stroke risks. Intervention: Characterize the ideal population for searching unknown atrial fibrillation and develop an understanding of actions that could be taken today to improve the diagnosis and management of AF. C: Compare two large populations with and without opportunistic screening of AF about stroke incidence. Outcome: MAIN OBJECTIVES 1. Compare two large populations with and without opportunistic screening of AF. 2. Relate the incidence of stroke episode with the AF diagnosis 3. Characterize the ideal population for searching unknown atrial fibrillation by making a multivariate predictor model. 4. Develop an understanding of actions that could be taken today to improve the diagnosis and management of AF. 5. Evaluate whether intervention results in improved outcomes
Vine™ is a permanent carotid filter designed to provide protection against embolic stroke in people with atrial fibrillation. It is implanted bilaterally in the common carotid arteries from a thin needle under ultrasound guidance. The procedure is performed without general anesthesia and takes minutes. The safety, feasibility and tolerability of Vine™ will be evaluated. Patients who are eligible will receive Vine™ and will be followed-up for a year after device implantation.
The current study will evaluate the potential of stimulating the R.auricularis of the vagus nerve located at the Fossa triangularis to ameliorate or suppress AF in the study Population!
The overall goal of this study is to assess the effectiveness of screening for undiagnosed atrial fibrillation (AF) using simple, efficient, and portable electronic health and mobile technologies in a healthcare system. The investigators propose to perform population-based screening for undiagnosed AF as part of usual care in patients ≥ 65 years when their vital signs are checked (spot-check) at scheduled outpatient visits in adult Massachusetts General Hospital (MGH) primary care clinics. Patients will receive routine care by their primary care provider (PCP) based upon the results of the screening during the visit. The investigators hypothesize that rates of AF detection among individuals ≥ 65 years in the MGH primary care network will be greater among patients in clinics assigned to the spot-check arm compared to patients in clinics assigned to the usual care arm of the study.
This study examines non-inferiority of pulmonary vein isolation (PVI) for persistent atrial fibrillation (AF) to extensive ablation; and reveals the effect of the presence or origin of AF trigger on outcomes of catheter ablation.
The purpose of the Confirm Rx SMART Registry is to collect real world data to assess the safety and performance of the Confirm Rx Insertable Cardiac Monitor (ICM) and system over a 12 month period. A sub-set of subjects enrolled in the Confirm Rx SMART Registry will meet the Post Market Clinical Follow-Up (PMCF) requirement for CE mark.
The objective of this registry is the characterization of patients with atrial fibrillation (AF) and/ or atrial flutter (AFL) with confirmed VHD who are prescribed edoxaban in a real life clinical setting.
