On October 29th, 2022, during the 33rd Great Wall International Congress of Cardiology, Asia Heart Society Congress 2022, in order to popularize the concept of coronary functional evaluation and promote the clinical application of computational coronary physiological indicators, RainMed Medical successfully held a satellite symposium of computational coronary physiology. The well-known experts in the field of cardiovascular were invited, and they discussed and prospected the latest progress of coronary functional evaluation technology, and shared the clinical experience of innovative computational physiology indicators caFFR and caIMR. It is worth noting that it is the first time that RainMed shared clinical cases of caIMR in satellite symposiums in such a national academic congress, which has attracted widespread attention and aroused heated discussion among participants.

Prof. Hui Chen: RainMed’s caFFR system and caIMR system can provide complete coronary functional evaluation conveniently and quickly, promoting the precise diagnosis and treatment of coronary heart disease

Prof. Hui Chen shared the new progress of functional evaluation in the diagnosis and treatment of coronary heart disease. He pointed out that FFR has become the "gold standard" for functional evaluation of coronary artery stenosis, and the importance of coronary microcirculation dysfunction in myocardial ischemia has gradually attracted attention. Compared with traditional guide wire evaluation techniques, both caFFR and caIMR can provide a convenient and rapid assessment of myocardial ischemia, thereby improving the clinical application rate of coronary functional analysis. In addition, the combination of caFFR and caIMR can evaluate myocardial ischemia conveniently and quickly, improve the application rate of coronary functional analysis and precisely guide the treatment of coronary heart disease.

Prof Xinjun Lei: RainMed Medical’s caIMR system overcomes the application difficulties of traditional guidewire-based IMR measurement technology, and is a powerful alternative to guidewire-based IMR

Professor Xinjun Lei made a special report on the clinical application of the index of coronary microcirculation resistance (IMR). He pointed out that IMR is an important index to evaluate microvascular function. Compared with CFR, IMR can specifically reflect coronary microcirculation function, and its repeatability is higher than CFR. RainMed’s caIMR system directly calculates IMR based on angiograms. Compared with guidewire-based IMR technology, there is no need of pressure guidewire, hyperemic agents, repeated injection of normal saline, which has outstanding advantages of safety, convenience and efficiency. RainMed’s caIMR system can replace the guidewire-based IMR and can be widely used in the diagnosis of coronary microcirculation function in patients with coronary heart disease and in the prognosis evaluation of coronary heart disease.

Prof. Hu Li: The simple and fast caIMR system of RainMed Medical can be widely used in the precision diagnosis and treatment of various types of coronary heart disease and promote the research progress of CMVD

Prof. Hu Li shared six clinical cases of his initial use of RainMed Medical caIMR system. The case types included CMVD of obstructive coronary artery disease, CMVD of complicated obstructive coronary artery disease, CMVD during emergency PCI, and a variety of situations, demonstrating the application potential of this system in the precision diagnosis and treatment of CHD. Prof. Hu Li said that compared with guidewire-based IMR, RainMed’s caIMR system is convenient and fast and provides a good diagnostic tool for CMVD, which can be widely used in the precision diagnosis and treatment of various types of coronary heart disease and promote the research progress of CMVD.

Prof. Xianglong Wei: RainMed’s caFFR system can better carry out preoperative diagnosis, intraoperative strategy formulation and postoperative effect evaluation of coronary heart disease. It is recommended for daily use

Prof. Xianglong Wei systematically demonstrated the application of RainMed’s caFFR system in precise intervention of coronary heart disease through abundant clinical cases. The 7 cases shared by Professor Wei involved the preoperative diagnosis and postoperative effect verification of three-vessel/multi-vessel lesions and bifurcation lesions, which helped us use caFFR system in a better and wide range. He said that compared with the conventional guidewire-based FFR measurement technology, caFFR system does not require interventional operation and the use of hyperemic agents. It can make a functional evaluation of multiple vessels conveniently and timely, and can better perform preoperative diagnosis, intraoperative strategy formulation and postoperative effect evaluation. It is recommended to use this system daily to guide interventional therapy.

The satellite symposium of RainMed Medical discussed the latest progress of coronary function evaluation technology, demonstrated the diagnosis and treatment advantages of non-interventional coronary function measurement system caFFR and caIMR, and shared its clinical experience. In this sharing, experts focused on displaying 6 clinical cases of caIMR system for the first time, which attracted the attention and aroused discussion of the participants. Experts said that RainMed’s caFFR system and caIMR system are functional evaluation indicators with pioneering significance. Their clinical application will improve the clinical application rate of coronary physiology evaluation indicators and improve the development level of precision medicine.

In the future, caIMR system will combine with caFFR system, which is an important part of functional diagnosis module and will be integrated on FlashBot vascular interventional surgery robot. It will build an integrated solution of cathlab diagnosis and treatment, and contribute Chinese wisdom to promoting precise coronary diagnosis and treatment.
