In recent years, the number of people with cardiovascular diseases in China has increased dramatically. The gradually increasing burden of cardiovascular diseases has become a major public health problem in China, making it urgent to prevent and treat cardiovascular diseases. In order to further promote and popularize Transcatheter Aortic Valve Implantation (TAVI) in China and the Asia-Pacific region, on October 25, 2019, 2019 PCR-CIT China Chengdu Valves was held in Chengdu, under the sponsorship of Sichuan International Medical Exchange & Promotion Association (SCIMEA), and joint-organization of West China Hospital of Sichuan University, PCR and CIT (China Interventional Therapeutics). Upholding the purpose of "joint learning, sharing experience and serving patients", the conference was based on the successful experience of PCR London Valves and focused on TAVI. Through hands-on basic training practice, live demonstration of surgery, academic lectures, step-by-step explanation of recorded cases and clinical case discussions, the attending medical workers could talk to top domestic and foreign experts, standardize their operation procedures, learn operation skills and prevention of complications, and improve their understanding of TAVI.

Professor Mao Chen, Professor Nicolo Piazza and Professor Christoph Naber acted as the executive chairmen of the conference, which attracted nearly a thousand well-known experts and medical research representatives in cardiovascular field from major medical and scientific research institutions in China and the Asia-Pacific region.

In the "Innovation Forum of Transcatheter Valve Therapy" held in the morning, the current status and outlook of TAVI were highlighted. In spite of the late start of TAVI technology in China, it has made rapid progress in recent years. Since TAVI valve was launched in China, its development has been greatly accelerated. The conference also demonstrated innovative solutions of Qiming Medical, CardioFlow, Peijia Medical, and Edwards Lifescience, accompanied by in-depth discussion and exchange.

Discussion and exchange during the conference

At the conference, topics were discussed such as case introduction, surgical strategy and key operation steps through TAVI live streaming. Details were shared with focus on the surgeon's introduction of live case learning goals, surgical strategies, and key points of equipment and technque. New progress, new technology and new equipment of valve intervention treatment in various fields such as aortic valve, mitral valve and tricuspid valve were demonstrated one by one in a systematic manner.

 Main venue

In the afternoon, the main venue conference demonstrated the CT assessment on site and analyzed the CT impact of live cases by distribution analysis mainly through live streaming. Through live streaming of ultrasound evaluation, demonstration and explanation of typical clinical cases, the participants understood the importance of ultrasound in TAVI preparation, intraoperative guidance and postoperative follow-up, as well as the existence of ultrasound in the diagnosis of aortic stenosis. They were also acquainted with the reason for difficulties in diagnosing aortic stenosis with ultrasound, and the step-by-step ultrasound evaluation method before TAVI.

By demonstrating selected TAVI images, the conference also introduced types of TAVI difficult anatomical structures and their impact on surgical strategies and results, shared the skills of handling difficult anatomical cases, penetrated into the learning of how to simplify and optimize the TAVI process, analyzed how to choose the appropriate patients for simplified TAVI, and discussed the balance between TAVI process simplification and safety. In addition, the main venue conference also set up an interactive case corner and invited experts to provide guidance and hands-on training, which effectively improved participants' transcatheter heart valve interventional treatment technology.
