Recently,The First Affiliated Hospital of Soochow UniversityCardiovascular MedicineDirector Jiang Tingbo, Director Zou CaoLed the team to successfully complete the clinical application of AccuPulse Cardiac Pulse Ablation System, one of the first batch in China. With multiple technological breakthroughs such as 7.5F ultra-thin adjustable loop diameter, intelligent impedance contact indication, and integrated mapping, modeling, and ablation, the AccuPulse Cardiac Pulse Ablation System is redefining the new standard for atrial fibrillation pulse field ablation treatment and providing an optimal solution for atrial fibrillation interventional therapy.
Case Summary
Female, 57 years old, 80kg, Paroxysmal Atrial Fibrillation
Catheter Model: AEPP0107
Voltage Comparison Before and After Ablation and Schematic Diagram of Pulmonary Vein Potential Isolation
The total duration of the surgery from preparation to completion was 125 minutes. The surgical procedure went smoothly, with good patient response during the operation and rapid postoperative recovery. The recorded voltage comparison charts before and after ablation, along with the schematic diagram of pulmonary vein potential isolation, clearly showed uniform and transmural ablation effects on the myocardial tissue. The pulmonary vein potential completely disappeared after ablation, achieving a 100% immediate isolation effect.
The ablation process involved pulsed electric field ablation at the ostia and vestibule regions of four pulmonary veins: LSPV, LIPV, RSPV, and RIPV. For each site, after six in-situ discharges, the catheter was rotated to perform overlapping discharges at the same location, accumulating 12 discharges per site. The total number of discharges for all four pulmonary veins (including ostia and vestibules) was 96. On the basis of completing the above standard ablation procedure, extended vestibular ablation of the top and bottom areas was performed by integrating three-dimensional electrical signals with catheter contact indications to achieve more complete electrical isolation.
Expert Commentary
Director Zou CaoPostoperative evaluation stated: "The adjustable loop diameter design of AccuPulse can adapt to pulmonary veins of different sizes. By adjusting the loop diameter, excellent contact can be achieved. The contact indication, combined with optional electrode discharge, enables precise localized ablation, providing operators with greater flexibility and further improving the success rate and safety of the procedure."
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.
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 improving the adaptability and safety of the operation.
Intelligent docking, real-time feedback:The system is equipped with AccuPulse's independently developed impedance contact prompting technology, which can monitor the catheter-tissue contact quality in real time, clearly indicate the contact status, assist operators in achieving stable and reliable catheter manipulation, 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, precisely locating lesions, and significantly reducing reliance on additional high-density mapping catheters in traditional procedures. This not only decreases surgical complexity but also saves on consumable costs, providing atrial fibrillation patients with a safer, more effective, and less invasive treatment option.
The successful application of PFA technology this time is an important achievement of AccuPulse in the continuous innovation and meticulous development within the atrial fibrillation treatment field. The system's efficiency, safety, and potential cost-effectiveness demonstrated during the procedure show broad clinical application prospects and market potential. In the future, AccuPulse will continue to deepen clinical collaboration with the First Affiliated Hospital of Soochow University, promote the standardized application and popularization of PFA technology, and commit to providing internationally leading one-stop atrial fibrillation diagnosis and treatment solutions for arrhythmia patients across China.
