Source: Medical Device FrontlineRecently,The First Affiliated Hospital of Henan University Successfully Conducts One of the First 3D Atrial Fibrillation Pulse Ablation Surgeries in ChinaThe implementation of this surgery represents another significant breakthrough in the field of arrhythmia treatment for the hospital's cardiovascular medicine department, reaching an advanced level in the industry.
It is understood that,This surgery was performed under local anesthesia guided entirely by the LEAD-Mapping® 3D system, which was launched by Jinjiang Electronic.The comparative test results with foreign-funded competitive products showed that Jinjiang Electronic's products are substantially equivalent to foreign-funded competitive products in terms of safety and effectiveness.
China's First Batch of 3D Atrial Fibrillation Pulse Ablation Surgeries Successfully Performed
It is understood that three months ago, Ms. Ma suddenly experienced palpitations, followed by syncope and loss of consciousness, causing her to fall to the ground. She visited another hospital but the cause of the condition was not identified. Subsequently, she had several episodes and sought medical advice from various sources without a clear diagnosis. As Ms. Ma’s symptoms have occurred frequently over the past three months, after consulting multiple sources, she specifically sought treatment at the First Affiliated Hospital of Henan University.
Ms. Ma was seen by the experienced Dr. Zhenhua Xia. After Director Wei Teng and his team from the Internal Medicine Department thoroughly reviewed the patient's medical history and the details of this episode, and ruled out other potential causes, they recommended that Ms. Ma undergo a long-term dynamic electrocardiogram (ECG) test. Three days later, when Ms. Ma experienced another episode, the dynamic ECG monitoring indicated paroxysmal atrial fibrillation, identifying the cause and confirming the diagnosis.And decided to adopt the innovative technology of pulsed field ablation (PFA) under local anesthesia for treatment.Under the meticulous guidance and coordination of Vice President Song Zhiming, this atrial fibrillation pulse field ablation (PFA) surgery was successfully completed by the team led by Director Teng Wei, in collaboration with Director Gong Guihong from the Cardiology Department, Director Tang Qiwei from the Third Ward of Cardiovascular Medicine, Director Wang Guoliang from the Cardiovascular Intensive Care Unit, Director Zhang Haibo from the Fifth Ward of Cardiovascular Medicine, as well as the nursing team from the Catheterization Laboratory.
The entire surgery was performed under local anesthesia guided by the LEAD-Mapping® 3D system.Young surgeon Xia Zhenhua, after completing the atrial septal puncture, first constructed a left atrial model under three-dimensional guidance. He performed a treatment strategy involving PVI (pulmonary vein isolation) and muscular sleeve potential intervention on the patient's pulmonary veins, achieving bilateral pulmonary vein isolation with verified bidirectional block. Subsequently, considering the influence of the superior vena cava trigger, pulse ablation was used to intervene in the superior vena cava. Post-ablation verification indicated good results, reaching the endpoint. The total operation time was 68 minutes, with an ablation time of 15 minutes and a total X-ray exposure time of 3 minutes.The patient remained fully awake throughout the procedure, tolerated it well, experienced no significant pain or discomfort, and the surgery was successfully completed.
3D Cardiac Electrophysiology Mapping SystemAtrial fibrillation is the most common elderly arrhythmia. According to statistics, there are currently about 20 million atrial fibrillation patients in China, and with the intensification of social aging, the number of atrial fibrillation patients will further increase.It is reported that in the field of cardiac electrophysiology treatment technology, pulsed field ablation (PFA) technology is based on the characteristic that the ablation threshold of myocardial cells is lower than that of other adjacent tissues. By delivering high-voltage pulsed electric fields, it causes irreversible electroporation (IRE) in cells, ultimately achieving a non-thermal ablation effect and blocking the conduction of abnormal electrical signals. Compared with ablation methods such as radiofrequency and cryoablation, PFA technology offers advantages such as tissue selectivity, fewer complications, faster ablation speed, higher surgical efficiency, simpler procedures, and shorter learning curves for operators, effectively addressing the clinical pain points of existing cardiac electrophysiology techniques.Jinjiang Electronic's latest generation LEAD-Mapping® Cardiac Electrophysiology Three-Dimensional Mapping System is a highly integrated, fully functional three-dimensional mapping system product.When used in conjunction with the company's self-developed配套导管, it can fully meet the clinical application needs of cardiac electrophysiology procedures, including cardiac electrophysiological mapping, catheter positioning and navigation, 3D modeling, feature point marking, and ablation information recording.
LEAD-Mapping 3D Cardiac Electrophysiology Mapping SystemIn terms of positioning and navigation functions, Jinjiang Electronic's LEAD-Mapping® Cardiac Electrophysiology 3D Mapping System builds upon the electrical positioning technology used in the first-generation 3D mapping system by further incorporating magnetic-electric fusion technology.By combining the current ratio with the magnetic field position through the electric field positioning module and the magnetic field positioning module, and calibrating via magneto-electric fusion, the three-dimensional spatial position of the catheter in the patient's heart can be accurately determined.And realize real-time visualization of catheter position and movement direction, solving the interference problem caused by biological activity on the electric field position, and improving the accuracy of positioning and navigation. The positioning accuracy of this product reaches the 1mm level.In terms of mapping and modeling functions,Used in conjunction with mapping catheters and surface electrodes, this product can rapidly acquire the 3D coordinate positions and ECG signals of various parts of a patient's heart.Through the built-in modeling algorithm, it can be converted into a three-dimensional equipotential map. Combined with the positioning and navigation function, it realizes the visualization of the patient's three-dimensional cardiac chamber structure and the real-time position of the catheter. At the same time, based on the built-in electrophysiological recording function, real-time and accurate waveform display output and background recording can be achieved, allowing for data traceability of various sites. The above functions can assist the surgeon in accurately locating the target tissue that causes abnormal heart rhythms, helping the surgeon perform ablation operations in a targeted manner.Pulse Field Ablation (PFA) is a novel, non-thermal, ultra-short duration, tissue-selective technology for rapid arrhythmia treatment.Its mechanism of action involves the phenomenon of irreversible electroporation (IRE) generated by high-voltage pulsed electric fields between cell membranes, which ablates local cardiac tissue and blocks abnormal cardiac electrical signal conduction pathways to treat arrhythmias.The successful implementation of this three-dimensional pulsed electric field ablation surgery not only provides a new option for catheter treatment of patients with arrhythmia but also sets a new benchmark for the First Affiliated Hospital of Henan University in atrial fibrillation treatment.More exciting content
