Scientists from the Institute of Personalized Cardiology at Sechenov University of the Ministry of Health of Russia have developed a technology to evaluate blood flow in the vessels of the heart using CT (computed tomography); this also makes it possible to predict the outcome of vasodilation surgery. The system responds within 10-20 minutes. socialbites.ca was told about this at the university.
Stenosis is a permanent narrowing of a blood vessel that threatens a person’s life. It can be solved using stenting, which is a special frame placement process that widens the blood vessel. An indicator of decreased blood flow in the coronary arteries, the vessels that carry blood to the heart, is used to decide whether it is necessary. However, intravascular sensors used to measure this indicator are expensive, difficult to sterilize, and the procedure itself requires a catheterization laboratory.
To increase the accessibility of blood flow assessment and simplify the procedure, scientists from Sechenov University have created “Virtual PRK”, a digital service for determining the degree of coronary artery stenosis using CT.
To calculate blood flow in a vessel, CT images and patient parameters are loaded into the program: pressure, pulse, stroke volume. With their help, algorithms create the structure of the coronary artery network, which is then used to calculate the pressure in different parts of the vessel.
“The system responds to what kind of blood flow is in each vessel and whether it needs to be repaired. And most importantly, it can create a model of the condition of the blood vessels after surgery, calculating what will happen if the vasoconstriction that is blocking blood flow is removed. Currently, 35% of stenting operations are performed.” does not lead to the expected effect, and the system will increase the efficiency of such operations,” Professor Philip Kopylov, director of the Institute of Personalized Cardiology, shared with socialbites.ca.
The scientists’ method uses a one-dimensional model of blood flow instead of three-dimensional calculations, which distinguishes it from foreign analogues. This replacement has almost no effect on accuracy, but allows you to get the result in 10-20 minutes, and not in 24 hours.
The development has already passed technical testing and is ready for clinical trials. Scientists hope to receive a registration certificate for the technology within six months.
