Active clinical trials for "Atrial Fibrillation"

It's hypothesized that a mean and range distance from the cavo-atrial junction to the area where there is complete loss of conductive tissue can be measured to better inform surgeons performing the Cox-Maze procedure. A patient scheduled for any cardiac surgery where visualization and mapping of cavo-atrial junction is possible could be entered into the study if they meet the inclusion/exclusion requirements.

This study shall determine whether XAPPORT - a mobile device app based on different guidelines, the summary of product characteristics of rivaroxaban, and clinical facts and practice - provides adequate guidance to physicians attending patients undergoing elective surgery, who have to interrupt treatment with rivaroxaban for surgery, in deciding how to approach the pre- and postoperative management of anticoagulation.

Question: Can atrial fibrillation (AF) cases in patients ≥ 65 years be easily detected in a primary healthcare environment using a smartphone device and iECG application as an opportunistic screening tool? Objectives: Detection of AF through cardiac rhythm abnormalities in patients ≥65 years old in an opportunistic screening program using a smartphone device/application Define the predictable value of the smartphone device with electrocardiogram (ECG) confirmation to detect AF in patients 65 years and older Correlate screened patients cardiovascular risk profile and those that register cardiac rhythm irregularities for a better description of the general characteristics of Colombian population

Atrial Fibrillation (AF) is a form of rapid irregular heart rhythm that starts in the upper chambers of the heart (called atria) and is often associated with many health problems. It can cause stroke, palpitations and heart failure. The management of long standing (chronic) AF may require additional medications and blood thinners, potentially for life. It may also require procedures where the heart is shocked with an electrical current to restore normal rhythm. Some patients require a procedure called radiofrequency ablation to address the arrhythmia. The purpose of this registry is to collect information on patients undergoing this combination of procedures into a database, and to then use this information for scientific study to improve the treatment of atrial fibrillation.

Single center investigator initiated sponsored by Guidant Boston Scientific Corp. to evaluate the benefit of ventricular rate regularization (VRR) in patients with congestive heart failure (CHF) and significant atrial fibrillation (AF) burden.

Study of patients with nonvalvular atrial fibrillation (NVAF) who are newly prescribed NOACs (Novel Oral Anticoagulants) in routine clinical practice in England

This study is an observational study without any hypothesis testing. It intended to observe the clinical application of electrophysiological mapping and catheter ablation of atrial tachycardia post atrial fibrillation ablation or cardiac surgery guided with Rhythmia System.

Purpose The primary purpose of the current project is to characterize unselected patients undergoing surgery developing post-operative atrial fibrillation (POAF), ultimately leading to a new risk-stratification model. Background and rationale According to rather scarce existing reports, it is estimated that 10% will develop POAF following abdominal surgery. It remains a challenge for the clinicians to predict which patients are at risk. POAF can be difficult to diagnose, as symptoms are often vague. Hence, the diagnosis may remain underreported leaving many patients without adequate treatment. Untreated atrial fibrillation is associated with increased morbidity and mortality, especially due to an increased risk of ischemic stroke. Methods Three-hundred adult patients admitted for surgery at the Digestive Disease Center at Bispebjerg Hospital will be examined by heart rhythm monitoring during hospitalization, i.e. pre-, peri- and postoperatively in the main SECAFIB-SURG study. Twenty study participants who develop POAF and 20 without POAF matched with these on sex, age and co-morbidity, will undergo additional cardiovascular examinations three months after surgery in the current sub-study. All patients will be followed for at least one year after surgery. The study is scheduled for completion within two years, commencing in January 2020. Perspective Creating a POAF risk-stratification model for patients undergoing abdominal surgery, could ensure timely diagnosis and treatment, hence, preventing complications associated with POAF.

In a population of patients with non-valvular atrial fibrillation (NVAF), and treated with oral anticoagulants (OAC) in routine clinical practice in England, this study will describe patients treated with each OAC, and to estimate and compare event rates of treatment discontinuation, bleeding, and healthcare resource utilisation (HCRU) across OAC treatments.

To compare heart function, symptoms, exercise capacity and quality of life in patients with Congestive Heart Failure (CHF) and Atrial Fibrillation (AF)before and after catheter ablation. Hypothesis: Restoration and maintenance of sinus rhythm by catheter ablation, without the use of antiarrhythmic drugs, in AF and CHF improves heart failure status.
