Filter by:The goal of this Ambispective cohort Study is to compare in patients with paroxysmal atrial fibrillation undergo pulse field ablation and radiofrequency ablation, respectively. The main question it aims to answer are:Comparison of the therapeutic effects of pulse field ablation and traditional thermal ablation on patients with paroxysmal atrial fibrillation and postoperative left atrial reverse remodeling.Participants will Perform pulse field ablation or radiofrequency ablation according to different groups, and cooperate to complete outpatient follow-up 6 months after surgery.
Antecedents: electrical isolation of pulmonary veins is the standard treatment for patients with atrial fibrillation. However, its efficacy is lower in persistent and chronic forms of this arrhythmia compared to paroxysmal atrial fibrillation. Many complementary techniques have been proposed, that added to pulmonary veins isolation, may reduce the recurrence rate of atrial fibrillation. However, none of them has obtained consistent results. Linear ablation aims to parcellate and modify the left atrial substrate responsible for atrial fibrillation maintenance. Previous studies have offered contradictory results using linear ablation. Methods: SUPAFER is a multicenter, 1:1 randomized clinical trial that compares the efficacy of pulmonary veins isolation alone vs pulmonary vein isolation plus an specific protocol of left atrial linear ablation. Contrary to previous studies, the specific SUPAFER linear ablation is systematic, homogeneous and target atrial areas that have not been systematically ablated in previous trials. The trial aims at demonstrating the superiority of the combined ablative approach during 1-year follow-up. Daily transtelephonic ECG samples a 30 days continuous ECG monitoring are used to maximize de detection of recurrences, even asymptomatic.
The goal of this interventional study is to describe the use of Edoxaban via PEG in patients with an indication to anticoagulation therapy. One arm will receive Edoxaban through PEG and the other arm will receive other Direct oral anticoagulants through PEG or subcutaneous heparin or LMWH. Once enrolled, patients will be treated with a single daily dose of Edoxaban (60 or 30 mg according to specific indications). At day 4 after enrollment (steady state), evaluation of anti-FXa activity and thrombin generation assay will be performed on peripheral whole blood samples. At months 6 and 12 patients will be asked to complete the ACTS (Anti-Clot treatment scale) questionnaire specific for anticoagulation. The main endpoint will be: the difference in the results of the Anti-Clot treatment scale questionnaire between the two groups evaluated at 12 months.
Pulsed-field catheter ablation is a promising new treatment method for patients with atrial fibrillation. The mechanism of cell damage here is different from that of classic catheter ablation, in which the ganglion plexuses around the pulmonary veins are also damaged and thus changes in the autonomic nervous system occur. The aim of the work is to find out, using heart rate variability, whether the autonomic system is less affected during pulsed field ablation than in classic radiofrequency ablation.
The purpose of this study is to demonstrate safety and effectiveness of the Biosense Webster (BWI) ablation system (THERMOCOOL SMARTTOUCH surround flow [STSF] catheter and TRUPULSE generator) when used for isolation of the atrial pulmonary veins (PVs) in treatment of participants with paroxysmal atrial fibrillation (PAF), an irregular heart rate that causing abnormal blood flow.
The main goal of this prospective pre-post implementation study is to investigate how a structured testing and treatment program for obstructive sleep apnea using the NOX T3s device and a Fitbit smartwatch with the FibriCheck algorithm impacts the proportion of atrial fibrillation (AF) in an AF population. Participants will wear the NOX T3s respiratory polygraphy device for one night at home. In case of a positive obstructive sleep apnea diagnosis, patients will be referred to the sleep clinic for a polysomnography examination. Patients positively diagnosed with polygraph will be monitored semi-continuously with the Fitbit smartwatch for three months. After the polysomnography examination, the positively diagnosed patients will be monitored semi-continuously for another three months after initiation of treatment (mostly continuous positive airway pressure (CPAP) treatment). Additionally, patients will be administered satisfaction and symptom burden questionnaires twice: right after the polysomnography examination and after the 3-month treatment.
Participants are being recruited at the inpatient department of the National Medical Research Center of Cardiology on a 'all-comers' basis. The enrolled participants will be divided into the main group (diagnosed with atherosclerotic cardiovascular disease (ASCVD)) and control (not diagnosed with ASCVD). The participants will have whole blood and serum collected at enrollment for further biobanking. A genome-wide association study will be carried out to determine the genetic determinants associated with atherosclerosis, coronary heart disease, acute coronary syndrome, etc., including a search for pathogenic variants.
Atrial fibrillation (AF) is the cause of 20% of strokes, and the risk of stroke in a person suffering from this arrhythmia increases by 5 times. Ischemic stroke in patients with AF is often fatal and, compared with stroke of other etiology, leads to the most pronounced disability and more often recurs. Accordingly, the risk of death in patients with AF-related stroke is 2 times higher, and treatment costs increase 1.5 times. The main interventional method of treating AF, available in most medical institutions, is the use of radio frequency and/or cryoenergy to eliminate destructive damage to the left atrium (LA). The aim of this study is to compare two different interventional methods and identify predictors of recurrence in patients with persistent and long-term AF.
SGLT2 inhibitors are oral anti-diabetic medications that were found to improve cardiorenal outcomes in patients with type 2 diabetes mellitus (DM), chronic heart failure with reduced and preserved ejection fraction, and chronic kidney disease. Recent evidence suggested that the use of SGLT2 inhibitors resulted in a significant reduction in atrial fibrillation (AF) over a mean follow-up duration of 2.6 years. Given the possible AF protective benefit with SGLT2 inhibitors use.
The purpose of this prospective randomized study is to assess whether a new treatment strategy consisting of circumferential Pulmonary vein isolation (PVI), left ROof linear (RL), Mitral Isthmus linear (MIL), and left anterior SEptal linear (ASL) ablation and left atrial appendage (LAA) Device occlusion (PROMISED procedure) is superior to the PVI combined LAA closure in enhancing the long-term success rate of catheter ablation in non-paroxysmal atrial fibrillation (AF) patients.
