Active clinical trials for "Atrial Fibrillation"

The primary objectives are to determine the correlation between rate of temperature decline and nadir cryoballoon temperatures rate of temperature decline and nadir esophageal temperatures during pulmonary vein isolation. To accurately measure the distance between the esophagus and the ostium of each pulmonary vein intra-operatively. To attempt to create recommendations for esophageal temperature-guided ablation in order to increase the safety profile of cryoballoon pulmonary vein isolation (PVI) by providing one center's experience. By trending cryoballoon ablation temperatures and subsequent esophageal temperatures, data trends may emerge and be predictive for esophageal ulceration formation. These trends may include: Distance between esophagus and pulmonary vein in patients who developed post-ablation esophageal ulcerations Intra-procedure esophageal temperatures in patients who developed post-ablation esophageal ulcerations Intra-procedure cryoballoon temperatures in patients who developed post-ablation esophageal ulcerations As well as to associate the development of symptoms (including dysphagia, chest pain, fever, "heartburn," or odynophagia) with the presence of ulcerations.

The purpose of the WHISH STAR study is to investigate whether or not those who are randomized to exercise intervention have higher rates of atrial fibrillation on review of medical records and, in a subset, on screening with a cardiac ECG patch monitor. We will also study whether those with a known history of AF have any changes in AF hospitalizations due to exercise.

In this prospective single-center trial, a wearable photoplethysmographic (PPG) sensor coupled with a cloud analytics service will be used to detect and quantify atrial fibrillation (AF) episodes in patients with known paroxysmal AF. Patients will simultaneously receive the PPG sensor in form of a smartwatch or bracelet and a Holter ECG for 48 hours. Correctly identified AF episodes and AF burden determined by both methods will be compared.

Postoperative atrial fibrillation (POAF) is a common complication that occurs in 30-50% of patients after cardiac surgery and increases morbidity and mortality and hospital length of stay. During the perioperative period, the discontinuation of beta-blocker treatment is known to be a risk factor for developing POAF in patient undergoing cardiac surgery. Early beta-blocker reintroduction is associated with lower incidence of POAF. Unfortunately, side effects of currently available beta-blockers (including esmolol), such as low blood pressure and excessive bradycardia and/or their extended duration of action, limit their use in the post-operative period especially for prevention. Landiolol, an ultra-short acting injectable beta-blocker, offers the advantage of significantly limiting low blood pressure events while increasing therapeutic efficacy in the treatment of POAF in cardiac and non-cardiac surgery. Landiolol, when used at low dose in the postoperative period, has been showed to reduce the incidence of POAF with no increased incidence of side effect as compared to standard of care. The limitation is that these promising data come from single center studies with limited samples and conducted exclusively in Japanese population. If landiolol is approved for use in the treatment of atrial fibrillation in non-Asian patients, there are no data on the prevention of POAF in cardiac surgery. The objective of this multicenter, double-blind, randomized, placebo- controlled phase III trial is to confirm that landiolol postoperative infusion is associated with lower incidence of POAF without excess of adverse events as compared to standard of care in a non-Asian population after cardiac surgery with sternotomy.

The goal of this clinical trial is to determine the efficacy of self-pulse monitoring in detecting atrial fibrillation (AF) in adult patients at increased risk of stroke. The main questions it aims to answer are: Is self-screening an effective modality for diagnosis of AF? Are there clinical differences and outcomes for patients who self-screen? Eligible participants will be randomized to either the intervention group or control group. The control group will continue with usual standard of care. Participants randomized to the intervention group will be asked to: View an online educational video to teach them the appropriate way to manually check their pulse for irregularities. Manually check their pulse for 30 seconds twice daily for 14 days. Patients who screen positive for irregularities will be sent a 14-day wearable cardiac monitor to assess for underlying arrhythmias. Researchers will compare the intervention group to the control group to see if there are clinical differences and outcomes.

A Prospective, Open, Multi-Center, Controlled Study to Evaluate the Safety, Performance and Efficacy of the CardiacSense1 for Detection of Atrial Fibrillation. The clinical study is intended to establish the efficacy and safety of the CardiacSense1 wearable device intended to monitor and detect heart arrhythmia, specifically atrial fibrillation (A-Fib) based on a comparison to a control device, which is an off-the-shelf cleared Holter ECG device

In this clinical investigation, the safety, feasibility and performance of the novel EnSite™ HD Grid Catheter mapping system for advanced high-density three-dimensional mapping will be studied in patients undergoing catheter ablation procedures for the treatment of non-paroxysmal atrial fibrillation (AF) or left atrial tachycardia (AT).

Atrial fibrillation (AF) is a major treatable risk factor for stroke, but it may be hard to detect because it is frequently silent and intermittent. New ambulatory cardiac monitoring technologies have the potential to improve early detection of AF. This trial investigates AF screening in primary care patients using the ZIO XT Patch, a wearable adhesive patch monitor that provides continuous ECG recording for up to 14 days, in addition to the WatchBP home blood pressure monitor that has built-in AF screening capability.

Atrial fibrillation (AF) is a frequent heart rhythm disorder, responsible for the formation of cardiac thrombi, which can embolize in the systemic circulation, responsible for strokes (Cerebrovascular accidents). AF increases the risk of stroke and stroke-related disability. Preventing the thromboembolic risk associated with FMD is therefore a public health issue. The reference treatment is oral anticoagulation but this treatment is contraindicated in patients with a history of intracranial hemorrhage. The percutaneous closure of the auricle is a recent technique which makes it possible to exclude this appendix from the left atrium where the majority of thrombi are formed in the framework of the AF. Comparative studies have shown the effectiveness of this technique, appearing to be similar to that of anticoagulation. However, in view of the per-procedural risk, the indication of closure was retained by the health authorities only in the event of a contraindication to oral anticoagulants in patients with non-valvular AF with a high thromboembolic risk. Patients with a history of intracranial hemorrhage are therefore candidates for this technique, but there are few studies where these patients were included. The risk-benefit must be demonstrated over the long term, in terms of ischemic, hemorrhagic recurrence and becoming functional and cognitive.
