Shulou( Report--, December 19, the first affiliated Hospital of Xi'an Jiaotong University recently issued a press release announcing that the team, led by Professor Yuan Zuyi, dean of the Cardiovascular Hospital, completed the first case of percutaneous coronary intervention (PCI) based on ultra-high definition dual-frequency intravascular ultrasound (IVUS) imaging system on December 12.

Ultra-high definition dual-frequency intravascular ultrasound imaging system and interventional catheter. (photo provided by the National Chuangchuang Center) quoted media reports that this is the world's first clinical experimental study of human coronary intervention surgery based on a dual-frequency intravascular ultrasound imaging system whose working frequency exceeds 100MHz, marking the official shift of ultra-high frequency IVUS technology from scientific research to a new stage of clinical application.

The UHD dual-band IVUS system is jointly developed by the National High performance Medical device Innovation Center (hereinafter referred to as "National Innovation Center") and Shenzhen Haoying Medical Technology Co., Ltd. (hereinafter referred to as "Huitai Medical holding Company") and Shenzhen Advanced Technology Research Institute of Chinese Academy of Sciences (hereinafter referred to as "Shenzhen Advanced Institute").

The previous intravascular ultrasound imaging technology has some limitations, single-frequency traditional IVUS technology can not achieve both imaging depth and resolution, clinicians need more safe, accurate and comprehensive guidance of PCI surgery.

Picture source: the first affiliated Hospital of Xi'an Jiaotong University has successfully broken through the innovative technologies such as the development of nanosecond high-voltage pulse ultrasonic circuit, ultra-high frequency ultrasonic transducer based on single crystal material and dual-probe imaging catheter for automatic image registration after two years of collaborative research and technological innovation.

Finally, we successfully developed a dual-frequency intravascular ultrasound imaging system and catheter with a working frequency of more than 100m with completely independent intellectual property rights.

Through a single acquisition, this product can obtain dual-frequency IVUS imaging with both high resolution and large imaging depth. Compared with the traditional IVUS, the resolution of the ultra-high frequency IVUS technology is nearly doubled, and it is expected to approach the OCT technology.

Before the intervention, interventional doctors were provided with more detailed details of the structure, abnormalities and lesions of the blood vessel wall, such as coronary artery dissection, distribution of calcified lesions, etc., so as to provide more targeted information for the formulation of treatment plans.

After the intervention, the effects of stent adhesion and expansion can be shown more clearly, which provides comprehensive guidance for the optimization strategy after stent implantation.
