Zhejiang Provincial People's Hospital Successfully Completes First Clinical Cases with AccuPulse® Pulsed Field Ablation System from AcoMed

Recently,Zhejiang Provincial People's HospitalAs one of the first clinical application units in China,CardiovascularDirector Wang Li's Team at AccuPulseProfessor Xu QiangApplication of AccuPulse by AccuPulse Medical^®Single-use Cardiac Pulse Electric Field Ablation Catheter and AccuBlator^®AccuPulse Medical Technology Co., Ltd.'s cardiac pulsed field ablation system successfully performed a pulsed field ablation (PFA) procedure on a patient with atrial fibrillation.

Substrate Mapping Before and After Ablation

The patient in this surgery was a 79-year-old female with recurrent atrial fibrillation after radiofrequency ablation. Based on preoperative examinations, the anteroposterior diameter of the left atrium was 46mm. An AccuPulse 20-25mm adjustable-loop cardiac pulse ablation catheter was selected for the ablation. The patient was in a state of atrial fibrillation at the start of the procedure. The total duration of the ablation surgery was only 40 minutes, including 1 minute for catheter modeling and mapping, 24 minutes for pulmonary vein ablation, and a total discharge time of 19.6 seconds. After the ablation, a 29mm occluder was successfully used to perform left atrial appendage closure.

Electrocardiogram Before and After Ablation

This surgery was for recurrent atrial fibrillation, and the procedure adopted a verification and supplementary ablation approach based on the recovery of pulmonary vein potentials. The operator particularly praised the design and operational performance of the AccuPulse PFA catheter: First, the catheter's flexibility was acknowledged, offering excellent handling; second, the combination of "A sheath + PFA catheter" was proven suitable for the delivery and operational needs of this case; third, and most importantly, the adjustable loop diameter design received strong approval. The operator recognized the practicality and design advantages of the AccuPulse variable loop PFA catheter in complex atrial fibrillation ablation procedures, noting its clear benefits in adapting to different pulmonary vein anatomical structures, achieving effective contact and ablation.

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 improving the adaptability and safety of the operation.

Intelligent docking, real-time feedback:The system is equipped with AccuPulse's self-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 the 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 stability and anatomical adaptability in PFA ablation catheters. It provides a precise and reliable solution for pulmonary vein isolation (PVI). The unique 7.5F adjustable loop diameter design of the AccuPulse cardiac pulsed field ablation catheter flexibly adapts to different anatomical structures of the pulmonary veins. Intelligent contact indication and flexible electrode selection give operators complete control, enabling accurate pulsed field ablation!

The Department of Cardiology at Zhejiang Provincial People's Hospital is a key clinical specialty in Zhejiang Province, a key discipline of traditional Chinese medicine in Zhejiang Province, a core unit of the Clinical Research Center for Cardiovascular and Cerebrovascular Diseases in Zhejiang Province, and a top-priority discipline within the hospital. It serves as the chair unit for both the Cardiac Rhythm Committee of the Zhejiang Biomedical Engineering Society and the Coronary Heart Disease Rehabilitation Committee of the Zhejiang Rehabilitation Medicine Association. The department was the earliest in Zhejiang Province to simultaneously qualify as a national- and provincial-level training base for three major cardiac interventional procedures: "coronary intervention, radiofrequency ablation, and congenital heart disease intervention." With strong technical expertise, advanced research equipment, and distinctive clinical features, it ranks among the leading departments in the province in terms of comprehensive strength. The department primarily treats various cardiovascular diseases, such as hypertension, coronary heart disease (angina pectoris, myocardial infarction), congenital heart disease (atrial septal defect, patent foramen ovale, ventricular septal defect, patent ductus arteriosus, etc.), arrhythmias (atrial fibrillation, atrial flutter, ventricular arrhythmias, paroxysmal supraventricular tachycardia, etc.), heart failure, and cardiomyopathy (dilated cardiomyopathy, hypertrophic cardiomyopathy, etc.). In recent years, the department has applied for six National Natural Science Foundation projects, 15 provincial and ministerial-level projects, over 50 department-level projects, and published more than 100 SCI papers.
