Multinational, investigator-initiated study of oral anticoagulation versus no anticoagulation for the prevention of stroke and other adverse cardiovascular events in patients with transient perioperative atrial fibrillation after noncardiac surgery and additional stroke risk factors.
Atrial fibrillation (AF) is the most common atrial arrhythmia. Ablation of AF is a recent technique, nevertheless, the success rates of ablation vary between 50% and 70% depending on the paroxysmal or persistent nature of AF. These rates are difficult to assess in routine practice because they are based on the recurrence of fibrillation. The Vitaphone is a non-invasive device, with which the patient can record a single-track ECG as his or her symptoms take place. The plot is then transmitted via the internet to the centre, which can thus diagnose a relapse of AF. The aim of our study is to correlate the rhythm and symptoms of 20 patients with Vitaphone 6 months after AF ablation and to compare them with 20 other patients receiving conventional monitoring.
This is a prospective, non-randomized, comparative, single-arm, open label, multi- centre, post-market clinical investigation involving an expected 74 subjects (minimum 40, maximum 118) suffering from paroxysmal AF with the aim to determine the accuracy of "definitive" AF detection (≥30 seconds) of the Cardioskin™ as compared to a 3-lead Holter recorder in patients with known paroxysmal AF.
A single-center, real word study of consecutive subjects who undergo radiofrequency ablation for paroxysmal AF using THERMOCOOL SMARTTOUCH®SF (STSF) Catheter guiding by Ablation Index (AI). Prospectively or retrospectively record 150 eligible subjects since 1st Jan 2019 to evaluate effectiveness and safety of STSF with AI.
Post-operative atrial fibrillation (POAF) is frequently observed after open-heart surgery. Despite numerous attempts to predict POAF, it remains a challenge to correctly identify the patients at risk. New technologies are available but not yet in cooperated in clinical guidelines and prediction models. We aim at identifying patients at risk of AF occurrence/recurrence after open-heart surgery by use of signal processed surface ECG (wavECG). The study is an explorative, prospective cohort study of 100 patients undergoing first-time elective open-heart surgery in the Left Atrial Appendage Closure by Surgery-2 (LAACS-2) trial (NCT03724318). Patients are examined by electrocardiogram (ECG), wavECG, transthoracic echocardiography and continuous heart rhythm monitoring. Primary endpoint is occurrence/recurrence of AF. Left ventricular diastolic dysfunction as evaluated by wavECG will be used to predict incidence of primary endpoint.
Atrial fibrillation is the most common rhythm disorder, affecting 2 to 3 percent of the population. One of the major complications is the occurrence of thromboembolic events, the thromboembolic risk can be predicted by the ChadsVasc score. Anticoagulant treatment is therefore almost always indicated, however, in view of the target population, anticoagulant treatment is sometimes contraindicated, justifying the appearance of alternative treatment such as occlusion of the left auricle by surgical or percutaneous means, with the placement of a prosthesis in the left auricle. Image fusion is a new imaging technique aimed at improving the spatial view of 2D images (made during a catheterization session) by repositioning in real time a 3D model obtained by reconstruction from scanner images of the structure of interest. Once the model has been redesigned, it follows all the consequences that the hemodynamicist wants to take and thus guides the gesture as well as possible. The purpose of this project is to evaluate the contribution of image fusion to per cutaneous occlusion procedures of the left atrium. This contribution will be evaluated by comparing the procedure time, the irradiation time, the amount of contrast material used between the procedures performed with the image fusion technique and without this new technique.
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.
