Professor Yu Bo, Dean of the Cardiovascular Disease Branch of the Second Affiliated Hospital of Harbin Medical University, used his own IVUS-OCT dual-mold imaging system and imaging catheter to lead the team to complete the world's first myocardial infarction surgery using its whole process. With this high -resolution and high -penetration "fire eye gold eye", the patient's blood vessels, vascular structure and lesions are clearly appeared in front of the surgeon, making the diagnosis and treatment of coronary heart disease not only more accurate but also "streamlined", and can be even more "streamlined". Coronary heart disease intervention surgery is really met, which truly meets clinical personalization.

According to reports, as a common detection technology for intravascular imaging, an ultrasound (IVUS) and optical coherent cutting layer imaging (OCT) are regarded as the "gold standard" of the diagnosis of coronary heart disease; Blood has a deeper imaging depth, but the disadvantage is that the spatial resolution is poor; the latter uses the principle of near -infrared light imaging, with higher resolution, and you can ideally compare plaque components, such as lipids, calcification, fiber tissue and thrombosis, etc. And its imaging penetration depth is limited. Therefore, it is difficult for a single IVUS or OCT to fully provide complete anatomy information inside the blood vessels and plaques. Sometimes in order to diagnose the cause and severity of coronary heart disease, patients have to accept two internal vascular images of IVUS and OCT, respectively.

Can we integrate the above two test technologies to innovate together to achieve the purpose of "marriage" for perfect penetration and resolution? Along this scientific research idea, as early as 2015, Yu Bo and his team set up and carried out the "IVUS-OCT dual-mode imaging system and imaging catheter development". After 7 years, it finally developed the first "IVUS-OCT all-in-one" to be used in the world. This new type of vascular imaging technology integrates optical imaging, acoustic imaging, hardware and software, and can obtain two internal imaging examination diagnostic data with a catheter and scanning imaging. Among them, the ultrasound scanning speed in the blood vessels reaches 40 mm per second, which is more than 20 times higher than before; and the length of the OCT scan also doubles, up to 150 mm per second, ensuring the accurate operation and simplicity, reducing the use of patient filmmaking agents , Shorten the surgery time, make the surgery more secure and effective. In late May this year, the "IVUS-OCT all-in-one" was a registered certificate issued by the State Drug Administration and was officially listed.

Mr. Wang, 76, suffered from hypertension and diabetes for many years. He suddenly had severe chest pain at home a week ago. He felt painful pain in the front area of ​​the heart. Local hospitals give static drug disposal. After the pain is slightly relieved, the cardiovascular disease branch of the Second Hospital of Harbin Medical University will be referred to it. After a comprehensive inspection of Professor Bo's team, Mr. Wang has a serious coronary stenosis and acute myocardial infarction. Accompanied by a small amount of blood thrombus, the plaques have a large load. According to the degree of condition, experts believe that interventional therapy is the preferred method for solving narrowing.

After communicating with the family members of the patient, Dean Yu Bo decided to implement the "IVUS-OCT all-in-one machine under the guidance of the whole process" for him. During the surgery, under the blessing of the IVUS-OCT all-machine machine, a catheter was pulled back at once to make the full view of the vascular, vascular structure, and lesion. More accurate coronary intervention treatment. In only 20 minutes, two brackets were precisely implanted for the patient's front -decreasing lesion blood vessel position. After the operation, Mr. Wang turned back to the general ward. He happily said to the doctor: "After doing the operation so quickly, my heart felt a lot bright, and it was not blocked at all!"

In an interview with reporters after surgery, Professor Yu Bo said that the IVUS-OCT all-in-one machine was independently designed and developed by our country, reflecting the ability and equipment level of my country's innovative medical devices, and realized the curve created from China to China created. Super -vehicle, which has contributed to the progress of coronary pulse in the world's scientific and technological innovation, serving economic and social development, and also contributed the global coronary intervention.
