Department of Macrovascular Surgery Acute aortic coarctation is the most dangerous disease in cardiac surgery, with rapid onset and high mortality. Under the leadership of Director Chen Xin, the mortality rate has been reduced from 50% to less than 10% after days and nights of hard work in recent years. Several families have been saved. This technology is leading in Jiangsu Province and advanced in China. Minimally invasive cardiac surgery technology With the development of technology, cardiac surgery now enters the era of minimally invasive, which is not only small incision, beautiful incision, but also small trauma, avoid splitting the sternum, reduce blood loss, and fast recovery after surgery. Our department has carried out more than 200 cases of minimally invasive cardiac surgery. Valvuloplasty technology Conventional valve replacement surgery requires long-term or short-term anticoagulation therapy after surgery, which is prone to complications such as bleeding or embolism, and patients have poor quality of life. As people’s standard of living improves and life expectancy increases, there are more and more degenerative valve lesions in clinical practice, and such patients are suitable for valvuloplasty. Valvuloplasty preserves the own valve, does not require lifelong anticoagulation, has a better long-term survival rate than valve replacement surgery, and has a high quality of life. Our department has been performing this technique for many years and has accumulated a wealth of clinical experience. Routine mitral valvuloplasty, tricuspid valvuloplasty and aortic valvuloplasty. Surgical atrial fibrillation ablation Most patients with severe cardiac surgery have atrial fibrillation, which leads to a serious decline in cardiac function and the formation of thrombus in the heart, which can easily lead to stroke, paraplegia or even coma if the thrombus is dislodged, and is extremely dangerous. The success rate of atrial fibrillation ablation in conjunction with heart surgery can reach 80% if the patient’s left atrial diameter is below 60 mm. This removes the risk of atrial fibrillation and improves the patient’s quality of life. Our department has been performing this technique for eight years and has accumulated clinical experience of about 1000 cases. Transfusion-free cardiac surgery Cardiac surgery deals directly with blood, and many patients used to lose blood intraoperatively and need blood transfusion after surgery. Blood transfusions are prone to infectious diseases. In the past three years, we have adopted various blood conservation and recovery techniques in cardiac surgery, and now 90% of cardiac surgery patients do not need blood transfusion. Significant medical resources have been saved. Real-time intraoperative esophageal ultrasound assessment techniques The accurate diagnosis and precise correction of cardiac lesions or malformations is the key to successful cardiac surgery. Real-time intraoperative esophageal ultrasound evaluation technology provides cardiac surgeons with another “eye” that can clearly diagnose, judge the effectiveness of surgery, evaluate the function of the heart, and remedy abnormalities, if any, on the operating table. This prevents catastrophic events from occurring after surgery. We are the first unit in the country to develop this technology, and it is routinely used in cardiac surgery. The 3D ultrasound, which is now in use, is an even better protection for valvuloplasty surgery.
