Recently,Tongji Hospital, Tongji Medical College, Huazhong University of Science and TechnologyAs one of the first clinical application units in China,Professor Wang Yan, Department of CardiologyLead its teamApplication of AccuPulse by AccuPulse Medical®Single-Use Cardiac Pulsed Field Ablation Catheter and AccuBlator®AccuPulse Medical Technology Co.Ltd's cardiac pulse electric field ablation instrument successfully performed a cardiac pulse electric field ablation (PFA) surgery on a patient with atrial fibrillation.

The successful completion of the surgery not only marks the official entry of this innovative domestically produced PFA system into the clinical application stage but also, with its three core advantages of integrated circular catheter mapping and modeling, efficient ablation, and excellent safety, provides a better option for atrial fibrillation interventional treatment.

Case Summary

Preoperative Substrate Mapping

The patient in this surgery was a 67-year-old female with paroxysmal atrial fibrillation. According to preoperative examinations, the left atrial diameter was 52mm. Ablation was performed using AccuPulse's 20mm fixed-loop cardiac pulse ablation catheter. The total surgery duration was 2 hours and 27 minutes, including 12 minutes for mapping and modeling and 62 minutes for pulmonary vein ablation.

Postoperative Substrate Mapping

The core strategy of the surgery was bilateral pulmonary vein isolation (PVI). During the procedure, a pulsed electric field ablation catheter was used. Based on the model and mapping information, electrodes were selected for ablation at the pulmonary vein ostium and vestibule areas. Additional points were added and the ablation isolation circle was expanded as needed. The specific ablation discharge details are as follows: LSPV discharged 28 times (6 times at the ostium, 22 times in the vestibule), LIPV discharged 30 times (6 times at the ostium, 24 times in the vestibule), RSPV discharged 71 times (23 times at the ostium, 48 times in the vestibule), RIPV discharged 78 times (30 times at the ostium, 48 times in the vestibule). After the ablation, detailed voltage mapping was performed to confirm complete electrical isolation of the bilateral pulmonary veins. The ablation line (large loop isolation) was intact with thorough blockage, and the surgery was successfully completed.

Expert Commentary

This surgery was performed under local anesthesia, thanks to the rapid pulse energy release time of the AccuPulse Cardiac Pulse Field Ablation System—single ablation energy release <0.2s. Performing atrial fibrillation pulse ablation without general anesthesia saved costs for the patient and avoided the occurrence of "anesthesia-related accidents" due to general anesthesia. The contact indication function of the AccuPulse Cardiac Pulse Ablation System proved to be stable and reliable, with its real-time monitoring of catheter-tissue contact quality and clear indication of contact status effectively supporting the smooth implementation of the predetermined ablation strategy: “PVI isolation + spot supplementation consolidation and expansion of isolation lines.” Despite the complexity posed by the significant enlargement of the patient’s left atrium, which increased the difficulty of accessing certain areas, the system demonstrated excellent controllability and stability during the main ablation process. The operator also praised its clear and intuitive 3D modeling function, which worked smoothly in conjunction with the Johnson & Johnson 3D system, further enhancing the precision of the surgical operation.

About AccuPulse Cardiac Pulse Ablation System

Flexible Adaptation, Precise Adherence:Its unique 7.5F adjustable loop diameter design can flexibly match the pulmonary vein anatomy of different patients, achieving personalized adaptation and significantly enhancing the adaptability and safety of the operation.

Intelligent docking, real-time feedback:The system is equipped with AccuPulse's self-developed impedance contact提示 technology, which can monitor the contact quality between the catheter and tissue in real time, clearly indicate the contact status, assist operators in achieving stable and reliable catheter control, and provide a solid guarantee for precise ablation.

Efficient Integration, Streamlined Processes:The circular catheter integrates mapping, modeling, and ablation functions, rapidly constructing a three-dimensional electroanatomical model of the heart during surgery, accurately locating lesions, and significantly reducing reliance on additional high-density mapping catheters in traditional surgeries. This not only decreases surgical complexity but also saves on consumable costs, providing a safer, more effective, and less invasive treatment option for patients with atrial fibrillation.

Safer:7.5F Ultra-thin Catheter, Reducing Tissue Damage

More Stable:Smart Snap Tips for More Precise Operation

More flexible:Adjustable loop diameter (15-20mm or 20-25mm) to meet different clinical choices.
