Ganglion Plexus Ablation in Persistent Atrial Fibrillation
Efficacy and Safety Study of Adjunctive Ganglionated Plexus Ablation in Patients With Persistent Atrial Fibrillation: A Randomized Controlled Trial
Study Overview
Status
Intervention / Treatment
Detailed Description
Study Design:
The study employs a parallel-group design with a 1:1 randomization ratio. Eligible patients meeting the specified criteria will be randomly assigned to either the conventional ablation group (pulmonary vein isolation + linear ablation) or the intervention group receiving additional ganglionated plexus ablation.
Intervention:
Control Group: Conventional ablation (pulmonary vein isolation + linear ablation) Intervention Group: Conventional ablation + ganglionated plexus ablation (left superior, left inferior, right anterior, and right inferior ganglionated plexi)
- Randomization and Sequence Generation:
To ensure randomness and comparability, a computer-generated random sequence will be utilized. Specific steps include:
- Pre-matching the numbers 1-50 with 50 random numbers.
- Allocating each random number equally to 2 groups, with the assigned numbers representing the order of patient enrollment.
Performing the above steps using R.
5. Data Collection: Baseline data, including demographics, medical history, and laboratory parameters, will be collected at the start. Intraoperative electrophysiological and ablation-related parameters, as well as postoperative adverse events, will be documented. Follow-up data will include postoperative survival, quality of life (assessed using the Atrial Fibrillation Effect on Quality-of-Life questionnaire), dynamic electrocardiogram recordings, recurrence of atrial fibrillation or other arrhythmias, rehospitalization for arrhythmia, and medication usage.
6. Endpoints:
- Primary Endpoints:
Recurrence of atrial tachyarrhythmias; Echocardiographic parameters; Procedure-related adverse events
- Secondary Endpoints:
Atrial fibrillation burden; Radiofrequency ablation time; Patient postoperative quality of life; Healthcare resource utilization
The trial's initiation date will be documented, and all procedures will be conducted at the Cardiovascular Department of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. The study will adhere to ethical guidelines and regulations, and informed consent will be obtained from all participants.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: GP Ablation Group
Participants in this group will undergo a combined intervention, including standard ablation (pulmonary vein isolation and linear ablation) and additional ablation targeting the autonomic ganglionated plexus (GP).
|
This intervention involves the targeted ablation of ganglionated plexus sites, specifically focusing on the left superior ganglionated plexus (LSGP), left inferior ganglionated plexus (LIGP), right anterior ganglionated plexus (RAGP), and right inferior ganglionated plexus (RIGP).
|
No Intervention: Standard Ablation Group
Participants in this group will undergo standard ablation treatment, which includes pulmonary vein isolation (PVI) and linear ablation.
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Recurrence of Atrial Tachycardia and Time to Recurrence
Time Frame: 91 to 365 days post-catheter ablation.
|
The first occurrence of sustained atrial arrhythmias (excluding atrial premature beats) lasting ≥30 seconds recorded between 91 to 365 days post-catheter ablation, including atrial fibrillation and atrial flutter, etc.

91 to 365 days post-catheter ablation.
|
Left Atrial Dimensions
Time Frame: 1 to 365 days post-catheter ablation.
|
Measurement of left atrial size, a key indicator of atrial remodeling, assessed as a primary outcome to evaluate the impact of the intervention on atrial structure.
|
1 to 365 days post-catheter ablation.
|
Left Ventricular Ejection Fraction, LVEF
Time Frame: 1 to 365 days post-catheter ablation.
|
Assessment of left ventricular ejection fraction as a primary outcome measure, providing crucial insights into post-intervention cardiac function and guiding the evaluation of the treatment's efficacy on overall heart performance.
|

|
Procedure-Related Adverse Events
Time Frame: 1 to 365 days post-catheter ablation.
|
Occurrence of adverse events related to the procedure during the perioperative or follow-up period, including but not limited to death, myocardial infarction, cardiac tamponade, and stroke.
|
