Filter by:This study is expected to include 166 subjects and Conducted at 11 research centers；The expected 12 month treatment success rate of using research instruments is 65%. Principle evaluation indexes： 1. Immediate success rate of surgery Immediately success of the surgery: complete pulmonary vein electrical isolation was achieved after ablation. 2. Immediate success rate of surgery=number of patients with immediate success of surgery/number of cases in subjects × 100% 3. Treatment success rate at 12 months after surgery Treatment success: Between 3 months and 12 months after ablation, there were no episodes of atrial fibrillation/atrial flutter/atrial tachycardia (duration ≥ 30 seconds, with clear electrocardiogram confirmation) without the use of antiarrhythmic drugs. Treatment success rate=number of successful cases of postoperative treatment in subjects/number of cases in subjects × 100% Secondary evaluation indexes： 1. The occurrence of hospitalization or emergency treatment due to symptoms caused by atrial arrhythmias during follow-up at 6 and 12 months after surgery; 2. Device performance evaluation; Safety evaluation indexes： 1. The occurrence of death, stroke, or transient ischemic attack; 2. The occurrence of surgical related complications, such as vascular puncture complications (pseudoaneurysm, arteriovenous fistula, etc.), heart perforation, atrial esophageal fistula, phrenic nerve injury, pulmonary vein stenosis (symptomatic), etc; 3. Clinically significant vital signs and related examinations; 4. The occurrence of other adverse events and serious adverse events during the trial period.
This study is a mulitcentre, randomized, parallel-group evaluation of pulse field ablation(PFA) and radiofrequency ablation(RFA) in patients being treated for symptomatic paroxysmal AF. Pulmonary-vein isolation (PVI) is the primary intention of catheter ablation in both groups.
This study aims to investigate the effect of reducing ablation time for a hybrid approach of vHPSD and AI-guided ablation using the QDOT Micro catheter in PVI among patients with PAF.
This is a Prospective, controlled, single-blind, randomized (2:1, Intervention:Control) clinical trial. The purpose of the study is to determine the role of adjunctive renal sympathetic denervation in the prevention of Atrial Fibrillation (AF) recurrence in patients with hypertension scheduled for a redo AF ablation procedure for paroxysmal or persistent AF. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention).
Background: quality of life is impaired in patients with paroxysmal atrial fibrillation. The purpose of this study is to explore the mediating effects of self-efficacy, coping, depression, and anxiety on the quality of life of patients with paroxysmal atrial fibrillation. Methods: It is a cross-sectional study trial. This study aims to enroll 100 patients with paroxysmal atrial fibrillation. Illness perceptions (Brief Illness Perceptions Questionnaire; BIPQ), coping styles (Carver Brief-COPE scale; B-COPE), depression Patient Health Questionnaire-9 ,PHQ-9),anxiety (The Generalized Anxiety Disorder Questionnaire, GAD 7) and quality of life (12-item Short Form Health Survey,SF12) will be analysed. This study intends to use correlation analysis and mediation analyses to assess the mediating effects of self-efficacy, coping, depression and anxiety on the quality of life of patients with paroxysmal atrial fibrillation.
The purpose of this study is to assess the performance and safety of using the investigational catheter.
High Power Short Duration Ablation Compared to Moderate Power Long Duration Ablation for Pulmonary Vein Isolation: safety and acute procedural outcome
Enrolled subjects will be treated with the Synaptic Cryoablation System. Treatment will include cryoablation of the pulmonary veins to achieve PVI. All subjects will be followed for twelve (12) months after completion of the index ablation procedure.
Paroxysmal AF subjects with a documented ECG event of AF will be recruited to the study To assess the efficacy of CardiaCare™ RR2 wearable home-care neuromodulation system in reducing AF burden and symptoms in Paroxysmal AF patients
The goal of this retrospective registry is to evaluate the efficacy and safety of Refralon®, concentrate for solution for intravenous injection, as chemical cardioversion in patients with paroxysmal and persistent atrial fibrillation and flutter in routine clinical practice. The main questions it aims to answer are: - What is the incidence of sinus rhythm restoration within 6 hours in patients with paroxysmal atrial fibrillation (AF)/atrial flutter (AFL) after the first dose of Refralon®? - What is the incidence of sinus rhythm restoration within 24 hours in patients with persistent AF/AFL after the first dose of Refralon®?
