Southern Medical University Zhujiang Hospital Successfully Completes One of China's First Clinical Cases Using AccuPulse® Adjustable Circular PFA System from Acepulse Medical

Recently,Zhujiang Hospital, Southern Medical UniversityAs one of the first clinical application units in China, at this hospitalDirector of CardiologyUnder the leadership of Professor Yang Pingzhen, Professor Song Xudong and Professor Yu Wenjie from the teamSuccessful Application of AccuPulse by AccuPulse Medical^®Single-use Cardiac Pulsed Field Ablation Catheter and AccuBlator^®Cardiac Pulse Field Ablation System, performed a cardiac pulse field ablation (PFA) surgery on a patient with atrial fibrillation.

CASE: Male, 70 years old, 65kg, Paroxysmal Atrial Fibrillation

The patient in this surgery was a 70-year-old male with paroxysmal atrial fibrillation. Based on the preoperative examination results, the operator selected the AccuPulse adjustable 20-25mm circular pulsed electric field ablation catheter. The total duration of the surgery was 64 minutes, and the procedure went smoothly. The total ablation time was only 16.625 seconds, successfully achieving 100% immediate pulmonary vein isolation.

Professor Yu Wenjie stated that the overall surgical experience using the AccuPulse Steerable PFA Catheter was highly efficient and smooth. The steerable feature of the catheter offers significant advantages when dealing with special anatomical positions or situations requiring multi-angle ablation. During the procedure, it allowed for rapid and precise positioning based on variations in cardiac anatomy, demonstrating clear convenience and flexibility, which effectively improved surgical efficiency. This successful application fully confirms the excellent efficacy and safety of the AccuPulse Cardiac Pulse Field Ablation System in treating paroxysmal atrial fibrillation, and it is hoped that it will better serve patients in the future.

Flexible Adaptation, Precise Contact: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 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 surgeries. 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.

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

AccuPulse Medical Technology Co., Ltd. has received approval for its disposable cardiac pulsed field ablation catheter, overcoming the challenges of catheter stability and anatomical adaptability in the PFA field, providing a precise and reliable solution for pulmonary vein isolation (PVI).

Department of Cardiology, Zhujiang Hospital, Southern Medical University (formerly the First Military Medical University), is a key discipline of Southern Medical University. It was approved as a master's degree authorization point in 1988, a doctoral degree authorization point in 1995, and one of the first doctoral student training disciplines in Guangdong Province. In 2000, it became a postdoctoral mobile station. The department includes outpatient services, wards, electrocardiogram rooms, cardiac catheterization laboratories, and research laboratories. Interventional diagnosis and treatment of cardiovascular diseases are the main features of the cardiology department. In the late 1980s, the department was among the earliest to implement selective coronary angiography (CAG) and percutaneous transluminal coronary angioplasty (PTCA) in Guangdong Province and even South China. The interventional diagnostic and therapeutic techniques encompass coronary stent implantation, radiofrequency ablation, congenital heart disease patching, rheumatic mitral valve balloon dilation, dual- and triple-chamber pacemaker implantation, and peripheral vascular balloon dilation. Among these, more than 2,000 cases of PTCA have been performed with high safety and a success rate of over 95%. Particularly, the hospital leads in China in emergency PTCA for acute myocardial infarction, complex lesions, left main lesions, and stent implantation.
