pulse field ablation, PFA, Paroxysmal Atrial Fibrillation, PAF
Brief summary
The purpose of this study is to verify the safety and efficacy of the cardiac pulse ablation system in paroxysmal atrial fibrillation to provide the basis for product registration and clinical application. The trial will be conducted at a clinical center with appropriate clinical cases, and paroxysmal atrial fibrillation ablation procedures will be performed by an authorized investigator using the trial product. The effectiveness and safety of the cardiac pulse ablation system in the treatment of paroxysmal atrial fibrillation will be verified by collecting the treatment success rate, immediate ablation success rate, procedure time and device use evaluation within 12 months after the procedure.
Interventions
DEVICEPulsed electric field ablation device;Cardiac Pulsed Electric Field Ablation Catheter
Routinely placing a coronary sinus electrode catheter, puncturing the interatrial septum, placing one sheath into the left atrium, confirming that the catheter is well in place, and setting the treatment time of the pulse ablation system in advance. Pulmonary vein-by-pulmonary vein ablation using a circular pulse catheter, waiting for the end of the pulse ablation phase and immediate effect confirmation.

Inclusion criteria
* ≥18 and ≤75 years of age. * Paroxysmal atrial fibrillation diagnosed by electrocardiogram or Holter ECG (including single-lead ECG recorder, lasting≥30s) within 1 year prior to enrollment. * Clinical diagnosis of paroxysmal atrial fibrillation. * Symptomatic patients who are ineffective or intolerant to at least one antiarrhythmic medication; or patients who are willing to undergo ablation despite not being on medication. * Fully understand the treatment protocol and voluntarily sign the informed consent form and be willing to undergo the tests, procedures and follow-ups required by the protocol.
Exclusion criteria
* Patients who have undergone left atrial surgery * Left atrial thrombosis * Patients of childbearing age who are unable to use effective contraception during the 12-month period after enrollment * Anterior and posterior left atrial diameter ≥ 50 mm * Left ventricular ejection fraction (LVEF) ≤ 40% * Previous atrial septal repair or atrial mucinous tumor * Active implants (e.g. pacemakers, ICDs, etc.) in the body * NYHA class III-IV cardiac function \[Appendix 1\] * Clear cerebrovascular disease within the last 6 months (including cerebral hemorrhage, stroke, transient ischemic attack) * Cardiovascular events within the last 3 months (including acute myocardial infarction, coronary intervention or heart bypass surgery, prosthetic valve replacement or repair, atrial or ventriculotomy) * Those with acute or severe systemic infections * Patients with severe liver or kidney disease, malignant tumors or end-stage disease that, in the opinion of the investigator, may interfere with the treatment, evaluation and compliance of this trial * Patients with significant bleeding tendency, hypercoagulable state and severe hematologic disorders * Patients who have participated or are participating in other clinical trials within 3 months prior to enrollment * Patients who have other conditions that the investigator considers inappropriate for participation in this trial.

| Rate of Treatment Success at 6-Month Post-Procedure | Refers to the postoperative phase (blank) after 6 months postoperatively | Refers to the postoperative phase (blank) after 6 months follow-up after process, without the use of class I and class III anti-arrhythmic drugs, by ECG, Holter, or Heart rate monitoring method based on equivalent (including a single lead electrocardiogram) confirmed that there are no last 30 s or af/the room/speed events account for the number of participants into the group of the proportion of the total number. |
| Rate of Treatment Success at 3-Month Post-Procedure | Refers to the postoperative phase (blank) after 3 months postoperatively | Refers to the postoperative phase (blank) after 3 months follow-up after process, without the use of class I and class III anti-arrhythmic drugs, by ECG, Holter, or Heart rate monitoring method based on equivalent (including a single lead electrocardiogram) confirmed that there are no last 30 s or af/the room/speed events account for the number of participants into the group of the proportion of the total number. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of Pulse Ablation equipment | 1 Day of surgery | System software operability;System operation stability;Hardware connection validity |
| Immediate success rate: pulmonary vein isolation after ablation | 1 Day of surgery | Refers to the proportion of the number of subjects electrically isolated in each AF patient after surgery to the total number of subjects enrolled. Validation was a 20-minute wait after successful electrical isolation of the pulmonary vein, followed by reconfirmation of pulmonary vein block |
| Evaluation of Pulse Ablation Catheter | 1 Day of surgery | Evaluation of catheter operation performance;Catheter ablation parameters |
Other
| Measure | Time frame | Description |
|---|---|---|
| The incidence of early onset (within 7 days of ablation) adverse events | Within 7 days after the surgery | The primary safety endpoint |
| Incidence of adverse events and serious adverse events associated with the study device | Within 12 months after sign the informed consent form | Secondary Security Endpoints |
