Cardiovascular electrophysiology is a core technology in the field of arrhythmia, and catheters, as the core surgical tool, are undergoing a leapfrog development from traditional radiofrequency ablation to intelligent and efficient technologies.

**3D Mapping Systems: “Smart Navigation” for Surgery**

Traditional two-dimensional catheters rely on the surgeon's experience, while 3D mapping systems (such as Abbott's EnSite™ X) use high-precision modeling to present the heart structure in three dimensions, helping surgeons quickly locate lesions. Abbott data shows that, combined with the new generation of catheters, surgical time can be reduced by 70%. The Columbus® system from the domestic manufacturer of minimally invasive electrophysiology has become the first domestically produced magneto-electric dual-positioning mapping system, covering more than 700 hospitals nationwide and having completed over 30,000 3D surgeries.

**Technical Highlights:** * **Dual Magnetoelectric Positioning:** Improves catheter stability and accuracy, reduces radiation exposure, and not only helps reduce the long-term exposure risk for doctors but also reduces the radiation dose received by patients, further enhancing the safety of the procedure. * **Rapid Modeling Algorithm:** Completes 3D cardiac modeling within 5 minutes, improving efficiency by 50%. * **Pulsed Electric Field Ablation:** A Dual Breakthrough in Safety and Efficiency Traditional radiofrequency ablation may damage surrounding tissues, while pulsed electric field ablation (such as the FARAPULSE technique) selectively ablates diseased cells using a non-thermal electric field, protecting healthy tissue. The team at the Second Affiliated Hospital of Xi'an Jiaotong University used this technology in conjunction with left atrial appendage occlusion, requiring only 2.5 seconds per discharge, shortening the procedure time to 27 minutes, and resulting in faster postoperative recovery for patients.

Clinical Advantages:

·Tissue Selectivity: Acts only on abnormal myocardium, avoiding nerve and vascular damage.

·Surgical Efficiency: Treatment time for complex atrial fibrillation is reduced to 1/3 of traditional methods.

Integrated Solution: End-to-End Innovation from Equipment to Service

The success of electrophysiological surgery depends not only on the catheter but also on the overall coordination of mapping systems, physician training, and postoperative support. Abbott's "Total Electrophysiology Solution" encompasses the EnSite™ X system and the TactiFlex catheter, empowering physicians to efficiently complete atrial fibrillation treatment. Minimally invasive electrophysiology provides end-to-end services through a "equipment + consumables + technical support" model and is deploying robot navigation technology to explore an intelligent future.

Industry Trends:

· Accelerated Domestic Substitution: The market share of domestic 3D mapping systems has increased from 10% to 30%.

The iteration of catheter technology is redefining the boundaries of cardiac electrophysiology therapy. As a participant in medical catheter manufacturing, we are committed to empowering clinical practice with innovative technologies and working with industry partners to promote the popularization of precision medicine.
