ENTERPRISE
Recently, the Department of Cardiovascular Medicine at Huaiyuan County Hospital of Traditional Chinese Medicine, under the leadership of Director Liu Kai, successfully applied ShineyoMedical's RhythPulse in collaboration with the catheterization laboratory medical team.®Pulsed Field Ablation Catheter Successfully Performs Pulsed Field Ablation (PFA) for an Atrial Fibrillation Patient. The successful implementation validates the comprehensive advantages of PFA technology in terms of tissue selectivity, efficiency, and safety, offering a safer and more efficient new treatment option for patients with atrial fibrillation.
Surgical Procedure
The patient is a 72-year-old male with a clinical diagnosis of persistent atrial fibrillation. The surgery was performed under local anesthesia. After routine vascular puncture, the transseptal sheath was advanced via the inferior vena cava to the right atrium, and the atrial septum was successfully punctured to establish access to the left atrium. ShineyoMedical's RhythPulse was used.® A 20mm catheter was used for left atrial modeling and substrate mapping with the support of a three-dimensional system.
Surgical Ablation Line
Bilateral Pulmonary Vein Isolation Procedure
After the modeling is completed, RhythPulse®The PFA catheter was delivered to the left upper pulmonary vein, and the voltage map indicated good substrate in the left atrium. Bilateral pulmonary vein isolation was then performed, starting from the left upper pulmonary vein. A total of 14 applications were delivered to the right pulmonary veins, and 18 applications to the left pulmonary veins. Pacing verification was conducted after pulse delivery, confirming bidirectional block of the pulmonary vein potentials. Post-procedure voltage maps showed successful isolation of both pulmonary veins. The overall ablation process took approximately 30 minutes.

Interpretation of Technical Advantages
In this surgery, Director Liu Kai of the Cardiovascular Department at Huaiyuan County Hospital of Traditional Chinese Medicine successfully performed a pulsed ablation procedure on the patient, thanks to his extensive experience and excellent technical skills. Atrial fibrillation (AF), one of the most common types of arrhythmia in clinical practice, is characterized pathologically by uncoordinated atrial electrical activity and ineffective atrial contractions, which impair normal blood-pumping function. In addition to symptoms such as chest tightness and palpitations, patients also face serious risks of complications like stroke and heart failure, significantly reducing their quality of life and threatening their health.
Pulse Field Ablation Breaks Through the Limitations of Traditional Radiofrequency Thermal Ablation
Surgical Highlights
1、Shorten Operation Time:The average operation time is shorter than traditional radiofrequency ablation, reducing the physical burden on patients;
2、Multiple Models, Multiple Choices:Ablation catheters with different diameters offer more procedural options.
3、Three-Dimensional Precision Positioning:Achieve precise targeted ablation through 3D, improving success rates.

【ShineyoMedical RhythPulse®-PFA System】
ShineyoMedical's RhythPulse®-PFA System is the first approved Pulse Field Ablation (PFA) system in China that integrates multi-channel, large focal points, and targeted ablation, primarily used for treating drug-refractory and recurrent atrial fibrillation and other rapid arrhythmias. Its core advantages include:
Large Focal Design:Using the world's first 10mm ring ablation catheter, a single discharge can cover a lesion area with a diameter of 10mm, increasing the ablation efficiency more than three times compared to traditional technology.
Targeted Ablation Technology:Equipped with an intelligent contact detection module, it monitors the contact status between the electrode and myocardial tissue in real time, reducing the risk of hemolysis caused by ineffective discharges, and decreasing postoperative plasma free hemoglobin levels by 50%.
Clinical Validation Excellence:In a clinical trial involving 151 cases, the immediate success rate was 100%, and the success rate for atrial fibrillation treatment at 12 months post-operation reached 85.07%, achieving an internationally leading standard.
