Release date: 2017-10-30 On October 22, 2017, at the International Symposium on Computational Science and Clinical Applications, the heart surgery team led by Professor Qiao Bin, a famous Chinese cardiac surgery expert, used the world's leading computer simulation technology to design Fontan surgery as an example. Through live broadcast, the “Fattan surgery for improving extracardiac catheters†was successfully implemented for a patient with complex congenital heart disease, and the world’s first computer-aided design of difficult Fontan surgery was unveiled for the first time in the world. The latest achievements in the integration of science and clinical medicine.

Live broadcast of Asia's first computer-aided design for difficult Fontan surgery
A single ventricle is a rare congenital complex heart malformation. The child has only one functional ventricle. The incidence is about 1:6500 in live infants, which is about 1.5% of congenital heart disease. Most single-ventricular patients have obvious congenital heart disease in early years, mainly due to congestive heart failure and arrhythmia, or sudden death due to unknown causes.
According to statistics, in the past 20 years, there are tens of thousands of single-ventricular patients who are still waiting for treatment because of ineffective treatment or traditional surgery. However, most patients and families are deterred from the high risk of surgery and poor prognosis of surgery. The traditional mid-thoracic thoracotomy is used to treat congenital heart disease, which is traumatic and difficult to stop bleeding, which seriously affects the physiological and mental health of the patient, and also increases the burden on the family. After Fontan invented a functional single-chamber surgical approach, in 1988 Deleve invented an extracardiac catheter for the treatment of a functional single ventricle. In China, Professor Wang Zengqi first reported the success of the Fontan surgery in the extracardiac catheter in 1992. There are many different surgical methods for functional single ventricles, many long-term complications, and unsatisfactory surgical results.
After 30 years of clinical research, Professor Qiao Bin's medical team applied a virtual and simulation technique based on computational fluid dynamics to design a new method for functional single-ventricular surgery, which achieved true physiological correction, systemic circulation and pulmonary circulation. There is no diversion between them, blood oxygen saturation is the same as that of healthy people, and there is no significant difference in quality of life and healthy people. At present, preoperative surgical planning, surgical implementation, and postoperative treatment and management are all standardized and standardized. Many patients have regained their health and the long-term surgical results are satisfactory. The "Fotan surgery to improve extracardiac catheterization" under the computer-aided design successfully implemented in Wuxi is a technical innovation. Before the operation, the doctor conducted a comprehensive examination of the patients. They collected the patient information and used modern fluid mechanics (CFD) to perform big data analysis and modeling on the computer. Based on the simulation data, the patient was designed according to the simulation data. The program aims to achieve the goal of "precise" treatment. The goal of precision science is to simplify the problems of nature through numerical operations to determine the physical quantity. At present, CFD has been developed from automotive and engine, industrial manufacturing, civil engineering, environmental engineering, and marine vessels to become a powerful tool for predicting and evaluating surgical outcomes, optimizing surgical design, and applying CFD to cardiovascular surgery. Design is a leap from natural science to medicine, a successful demonstration of interdisciplinary cooperation, a manifestation of the "artisan spirit" of medical practitioners, a new milestone in the development of single-ventricular treatment, and an opportunity to promote the development of integrated medicine and translational medicine. .
